 The principle of operation of the optoelectronic node can be as follows.

 In the initial state (see Fig. 1, 10), the external optical fibers 60, 61, 63 and 64 of the optoelectronic node are connected through fiber-optic connectors 28 with windows 19, 20, 22, 18 connected to open optical switches 40, 29, 29 and 23, respectively, and the external fiber 62 is connected through a fiber optic connector 28 with a window 21 connected to a closed optical switch 40.

 The luminous flux 65 through the light guide 60, window 19, the open optical switch 40, the light guide 3 and the open optical switch 29 is fed to the photodiode 26, from which information is collected in electronic form. To exclude the passage of optical information into the splitter 5 in the optical switch 29 by applying from the control module 2 a control voltage, for example 2.5 V, an optically opaque zone 39 is formed.

 With the optical switches 29 open, installed at the inputs of the couplers 5 and 6 connected to each other and connected to the windows 17 and 20, respectively, the information light flux 66 is supplied from the LED 27 to the optical fiber 61. To exclude the passage of optical information to the optical fibers 3, 4 and 62 in optical switch 29 of the splitter 5, in the optical switch 29 and 40 of the splitter 6 are formed optically opaque zones 67, 68 and 44, respectively, by applying from the control module 2 a control voltage, for example 2.5 V.

 With the optical switches 29 and 23 of the light guide 4 open, the light flux 67 through the light guide 63, the window 22, the light guide 4 and the window 18 enters the light guide 64 for further transmission of optical information to an external telecommunication system. To exclude the passage of optical information into the splitter 6 in the optical switch 29 of the optical fiber 4 by applying from the control module 2 a control voltage, for example 2.5 V, an optically opaque zone 69 is formed.

 To change the state of the optoelectronic node, the state of the optical switches is changed, which, in turn, allows you to change the conditions for switching light fluxes from external telecommunication networks.

 To supply the light flux 70 from the fiber 61 through the window 20 to the photodiode 26, close the optical switch 40 of the fiber 3 (see Fig. 1, 10, 11) by forming an optically opaque zone 44 using a 2.5 V control voltage supplied from the control module 2, turn off the optically opaque zones 39 and 67 in the optical switches 29 of the light guide 3 and the splitter 5 by removing control voltages and form the optically opaque zone 72 in the optical switch 29 of the splitter 5 by applying a control voltage from the control module 2 to Example 2.5, thereby forming an optically transparent optical information transmission channel in the form of the luminous flux 70 from the fiber 61 to the photodiode 26.

 To supply the light flux 66 from the LED 27 to the optical fiber 63, an optically opaque zone 73 is formed and the optically opaque zone 68 is turned off in the optical switch 29 of the splitter 6 by supplying a control voltage, for example 2.5 V, from the control module 2, the optically opaque zone 69 is turned off in the optical switch 29 of the optical fiber 4 by removing control voltages, block the passage of light fluxes through the optical switch 23 by shifting a length of the optical fiber 25 beyond the optical fiber 4. As a result, miruetsya optically transparent optical data transmission channel in the form of the luminous flux 66 from the LED 27 to the light guide 63.

 Using the proposed switching technology in the optoelectronic node of the light fluxes in the infrared and visible optical ranges to the photodiodes or LEDs, optical fibers of the optoelectronic node, it is possible to carry out logical operations with incoming optical information, to amplify optical signals by connecting amplification devices and their joint switching to the corresponding photodiodes and LEDs, to store information by connecting information storage devices to the photodiodes, ive processor information processing by connecting to the optoelectronic assembly of electronic processors, retransmission light information flows with their switching in telecommunications systems.

 In the first mode, an optical light flux 332 is supplied to the input of the fiber 330, which at a certain angle of reflection, depending on the deflection angle of the first output of the V-shaped liquid crystal coupler 303 relative to the internal reflection surface of the fiber 330. The condition for the light flux 332 to enter the first output of the splitter 303 is equality of the angle of reflection of the light flux to the angle of deviation of the first output of the splitter 303 relative to the reflective surface of the fiber 330.

There is no reflective coating of the fiber at the points of connection with the optical switches 482-485. The convex fragments 479-482 of the optical fiber 478 are actually V-shaped couplers made of fiber optic material. In turn, the optical liquid crystal switches 482 to 485 are connected to a laser 486, a photodiode 487, a laser 488, and a photodiode 489, respectively.

After passing through the zigzag splitter 478, the light information stream enters the output of the optoelectronic node in the optical fiber 499.

 The second mode of operation of the optoelectronic node (Fig. 56) is associated with the formation of the light information stream 507 by one of the lasers 488 of this optoelectronic node, the operation of which is controlled by the control module 496. In the splitter 481, which represents the convex part of the zigzag splitter 478, the light information stream 507 is divided into two directions that go to the output optical fibers 498 and 499 of the optoelectronic node. The passage of the light information stream 507 inside the zigzag splitter 478 is controlled by photodiodes 487 and 489.

The zigzag liquid crystal splitter 511 is made of four V-shaped liquid crystal splitters 513-516 connected in series with each other with their side outputs (Fig. 58) with one input om and three outputs each. The zigzag shape of the splitter 511 is formed by turning the splitter 514 relative to the splitter 513 by 180 ^° , the splitter 515 relative to the splitter 514 by 180 ^° and the splitter 516 relative to the splitter 515 by 180 ^° .

The optical switch 518 (Fig. 58), made in the form of a group of control transparent electrodes 522, 523, located opposite each other with the placement of liquid crystal material 524 between them and installed with the possibility of forming between these electrodes control voltages supplied from the control modules 525, 526 ( Fig. 57, 58) of an optically opaque zone 527 in the liquid crystal material 528. The optically opaque zone 527 is made reflective. The control electrodes 522, 523 are located on the internal reflective surfaces 517 of the V-shaped coupler 513, as well as in the cross section of the central output 529 of the coupler 513, in the form of a multilayer structure in the sequence: liquid crystal layer 530, electrode 523, liquid crystal layer 528, electrode 522.

 The optical liquid crystal switch 518 (Fig. 58) also contains a second group of control transparent electrodes 531, 532, which are superimposed on the control electrode 523 overlapping with each other to form a common overlap zone in which a dielectric layer 533 is placed between the electrodes.

Optically opaque zones 558 are made reflective. In a constructive embodiment, the optically opaque zones 558 formed between the electrodes 551 and 553-557 can be made in the form of a diffraction grating controlled by the voltages supplied by the control modules 525 and 526.

 Modes of operation of the laser system.

 The first mode of the laser switching system. In the initial state, the optically opaque zone 558 (Fig. 59) of the light emitting matrix 540 installed at the output "1" and "6" completely turns off the lasers 545-549 and the output fibers 544 and 570 (Fig. 60). The optical liquid crystal switches 536, 571, 572 and 573 are closed. The optical liquid crystal switches 518 and 521 are fully open (FIG. 58). The optical liquid crystal switches 519 and 520 are open only in the direction of passage of the light information flows into the optical fibers 568 and 563, respectively. When the light information stream 576 is input to the input “10” of the optical fiber 509, it is switched to the output “8” of the optical fiber 568. When the light information stream 577 is input to the input “5” of the optical fiber 510, it is switched to the output “3” of the optical fiber 563.

 The second mode of operation of the laser system. In the initial state, the optical switches 518 and 536 (FIG. 61) forming the laser cavity are open. In this case, the optically opaque reflective zones 534 and 535 are formed by control voltages supplied from the control modules 525 and 526 to the control electrodes 522 and 531, 532, respectively (Fig. 57). Optically opaque reflective zones 558 are formed by control voltages supplied from the control modules 525 and 526 to the control electrodes 554-556 of the light-emitting matrix 540 installed at the outputs "1" and "9" (Fig. 61, 62). The optical laser resonator is configured to accommodate optically opaque zones 534 and 535 at a distance between them that is a multiple of half the wavelength of the radiation of the lasers 545-549. In addition, the optical laser resonator is configured to accommodate optically opaque zones 558 of the light emitting matrix 540 of the output "1" and 558 light emitting matrix 540 of the output "9" at a distance between them that is a multiple of half the wavelength of the radiation of the lasers 545-549. In the first use case, the width of the optically opaque zones 534 and 535 is greater than the width of the optically opaque zones 558 of the light emitting matrices 540 mounted at the outputs "1" and "9". The transparent electrodes 553, 557 and 551 do not supply control voltage from the control modules 525 and 526.

 When the in-phase radiation of light information flows 578, the lasers 545, 546, 549, 550 (with a radiation power of several mW) begin to operate in the resonant mode. When the radiation power in resonance is reached (radiation power from several hundred mW to several W), exceeding the limit value of the power barrier 580, corresponding to the thickness of the optically opaque zones 558, a spontaneous pulse signal 579 passes through the barrier 580 of the optically opaque zone 558 in the direction of exits "1 "and" 9 "(Fig. 61.62).

 In the event that the width of optically opaque zones 534 and 535 is less than the width of optically opaque zones 558, when the lasers 547, 548 are in-phase (with a radiation power of several mW), their laser radiation power is increased in the form of light information flows 578 followed by the passage of a spontaneous pulse signal 581 (radiation power from several hundred mW to several W) through the power barrier 582 of optically opaque zones 534 and 535 to the side branches of the laser resonator 583, 584 (Fig. 63, 64).

 The third mode of operation of the laser system. In the initial state, the optical liquid crystal switch 536 is closed (Fig. 58, 65). An optically opaque reflective zone 587 is formed between the transparent electrodes 523 and 537. The optically opaque zone 558 blocks the passage of light information flows from lasers 548-550. No transparent voltage is applied to the transparent electrodes 553-555 and 551 from the control unit 526. Optically opaque zones that block the passage of light information flows from lasers 545-547 are not formed. When the lasers 545-547 are turned on, the in-phase light information streams 585 passing through the transparent electrodes 553, 554 and the liquid crystal layer 586 are reflected from the optically opaque light-reflecting zone 587 and enter the light guide 541 of the output "9" (Fig. 58) in the form of a light flux 588 (Fig. 65).

 The fourth mode of operation of the laser system. In the initial state, the optical liquid crystal switch 518 is open in its central part (Fig. 66). The optically opaque retro-reflective zones 534 and 535 are formed by control voltages from the control module 526. The optical liquid crystal switch 536 is open. Optically opaque zones 558 of the light-emitting matrix 540 located at the output "9" are formed only at the outputs of the lasers 547, 548 and the optical fiber 541 (Fig. 62) by the control voltages supplied from the control module 526 to the transparent electrodes 554-556 and 551. To the transparent electrodes 553, 557, and 551 do not supply control voltage from the control module 526. Optically opaque zones blocking the passage of light information flows from lasers 545, 546, and 549, 550 to the optical liquid crystal switch 536 are not formed. Optically opaque zones 558 of the light-emitting matrix 540 located at the output "1" are formed at the outputs of the lasers 545-550 (Fig. 67) by control voltages supplied from the control module 525 to the transparent electrodes 553, 554 and 556, 557 and 551. To the transparent electrodes 555 and 551 do not supply control voltage from the control module 525. An optically opaque zone that blocks the passage of light information flows from the optical switch 518 to the output "1" is not formed. The light information streams 589 (Fig. 66) from the switched-on lasers 545, 546, 549, 550 of the output "9" first go to the optical switch 536, then to the optical switch 518 and then in the form of a light information stream 590 to the light guide 544 of the output "1" .
