The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Example one
Referring to fig. 1, the present embodiment provides an optical module 1, which includes a compact optical transceiver 2, and referring to fig. 2, the compact optical transceiver includes an optical platform 3, and a first optical path module, a first reflector 501, a second reflector 502, and a second optical path module, which are sequentially fixed on the optical platform 3 along an optical propagation path 9. The reflecting surface of the first mirror 501 and the reflecting surface of the second mirror 502 are perpendicular to each other.
It can be understood that, when the reflector surfaces of the first reflector 501 and the second reflector 502 are perpendicular to each other, the propagation path of light will be in a U shape, accordingly, the first light path module, the first reflector 501, the second reflector 502 and the second light path module can also be in a U shape arrangement, compared with the traditional in-line arrangement layout, the U shape arrangement can effectively reduce the length of the light transceiver, and further meet the length requirement of the light transceiver, and the compactness of the device is improved.
The optical platform 3 includes a first strip area 301 for placing the first optical path module and the first reflector 501, and a second strip area 302 for placing the second optical path module and the second reflector 502. The first strip area 301 and the second strip area 302 are located on the same side of the optical bench 3.
It should be understood that, in order to minimize the length of the compact optical transceiver device, different optical path components may be divided into the first optical path module or the second optical path module according to the size of each optical path component itself and the distance between two adjacent optical path components. In this embodiment, the first optical path module includes a chip 401 and a collimating lens component 402, the second optical path module includes a combiner/splitter 601 and a focusing lens 602, at this time, the length of the first strip area 301 is almost equal to the length of the second strip area 302, and the length of the compact optical transceiver can be minimized. In some other embodiments, the first optical circuit module includes a chip 401; the second optical path module comprises a collimating lens, a combiner/demultiplexer 601 and a focusing lens 602; or, the first optical path module includes a chip 401, a collimating lens and a multiplexer/demultiplexer 601; the second optical path module includes a focusing lens 602.
Preferably, an isolator may be disposed in front of or behind the focusing lens 602 according to the requirement of unidirectional light transmission.
In this embodiment, the compact transceiver further includes a package housing 7, a containing groove 701 is disposed on one side of the package housing 7, and the optical platform 3 is located in the containing groove 701, so that the whole structure is square and flat, and is convenient to install.
In the compact optical transceiver and the optical module provided by this embodiment, the two reflecting mirror surfaces are arranged to change the propagation path of light from one type to a U-type, so that each optical component is arranged on the optical platform 3 according to the U-type, the space in the width direction is fully utilized, the length of the compact optical transceiver is reduced, and the requirement on the length of the optical transceiver is reduced.
Example two
Referring to fig. 1, the present embodiment provides an optical module 1, which includes a compact optical transceiver 2, and referring to fig. 3 to 6, the compact optical transceiver includes an optical platform 3, and a first optical path module, a first reflector 501, a second reflector 502, and a second optical path module, which are sequentially disposed along an optical propagation path 9. The reflecting surface of the first mirror 501 and the reflecting surface of the second mirror 502 are perpendicular to each other. The first optical path module and the first reflector 501 are located on one side of the optical platform 3, and the second optical path module and the second reflector 502 are located on the other side of the optical platform 3. Between the first mirror 501 and the second mirror 502 is a light-transmitting space.
Specifically, the first optical path module and the second optical path module are respectively arranged at two sides of the optical platform 3, so that the light needs to be reflected by the first reflecting mirror 501 and the second reflecting mirror 502 with mutually perpendicular reflecting mirror surfaces to enable the light to sequentially pass through each optical component. The difference between this embodiment and the first embodiment is: in the first embodiment, the requirement for the space in the length direction is reduced by fully utilizing the space in the width direction of the compact optical transceiver device, while the requirement for the space in the length direction is reduced by fully utilizing the space in the thickness (i.e., height) direction of the compact optical transceiver device. The same as the first embodiment, when the reflecting mirror surfaces of the first reflecting mirror 501 and the second reflecting mirror 502 are perpendicular to each other, the propagation path of light will be in a U shape, and accordingly, the first light path module, the first reflecting mirror 501, the second reflecting mirror 502 and the second light path module can also be in a U shape arrangement.
Unlike the first embodiment, since the first reflecting mirror 501 and the second reflecting mirror 502 are disposed on two sides of the optical platform 3, a light-transmitting space for light to pass through must be provided between the first reflecting mirror 501 and the second reflecting mirror 502. Specifically, in the present embodiment, the first mirror 501 and the second mirror 502 are both located outside the optical platform 3, so that the optical platform 3 does not block the light transmission between the first mirror 501 and the second mirror 502, i.e. the light-transmitting space is a space outside the optical platform 3. Alternatively, in some other embodiments, the optical platform 3 may also extend into the space between the first reflector 501 and the second reflector 502, and in order to avoid the optical platform 3 blocking the light transmission between the first reflector 501 and the second reflector 502, a through groove may be provided at the area of the optical platform 3 between the two reflectors, and the through groove is a light-transmitting space.
Similarly, in this embodiment, in order to minimize the length of the compact optical transceiver, different optical path components may be divided into the first optical path module or the second optical path module according to the size of each optical path component and the difference between the distance between two adjacent optical path components. Preferably, the first optical path module includes a chip 401 and a collimating lens component 402, and the second optical path module includes a combiner/splitter 601 and a focusing lens 602.
In this embodiment, the package housing 7 is provided with a containing groove 701, the optical platform 3 is located at one end of the containing groove 701, and the first reflecting mirror 501 and the second reflecting mirror 502 are fixed at the other end of the containing groove 701. A limiting boss 702 is arranged at the bottom of the accommodating groove 701, and the height of the limiting boss 702 is smaller than the depth of the accommodating groove 701; the optical platform 3 is fixedly connected with the limiting boss 702, and divides the accommodating groove 701 into a first storage space for storing the first light path module and a second storage space for storing the second light path module.
Optionally, the first optical path module is fixed to the bottom of the accommodating groove 701, and the second optical path module is fixed to the optical platform 3.
It should be noted that the height of the limiting boss 702 should be not less than the height of each optical component in the first optical path module, so as to store the first optical path module in the first storage space. The optical platform 3 is fixed on the limit boss 702, so as to divide the containing groove 701 into two parts, which is beneficial to fully utilizing the height space of the compact optical transceiver.
In this embodiment, a raised boss 703 is further disposed at the bottom of the receiving groove 701, a heat dissipation member 8 is fixed on the raised boss 703, and the chip 401 is fixed on the heat dissipation member 8. Preferably, the heat radiating member 8 is a heat pipe or a ceramic heat radiating fin made of CuW, Cu, Si, AlN or the like. Reverse chip 401 of pasting dress transmits the heat for packaging shell 7 through heat dissipation part 8, compare with the tradition technical scheme who is fixed in chip 401 on optical platform 3, packaging shell 7 has bigger heat radiating area, and optical platform 3 itself just need be other light path subassemblies to dispel the heat moreover, such structural design not only can realize chip 401's quick heat dissipation, can also alleviate optical platform 3's heat dissipation burden, be favorable to improving compact optical transceiver's stability.
Optionally, the optical platform 3 contains a metal material with good heat conductivity, such as Cu or Au, inside, so as to improve the heat dissipation performance of the compact optical transceiver device.
Optionally, a light fixing seat is further fixedly arranged on the optical platform 3, and the diameter of the optical fiber insertion hole in the light fixing seat is matched with the size of the bare optical fiber. Generally, the light skin is the protective layer, so traditional optical fiber jack diameter and protective layer phase-match, and in this embodiment, optical fiber jack and bare fiber phase-match are favorable to reducing optical fiber jack's diameter, improve the radiating efficiency.
The optical module provided by this embodiment is provided with two reflecting mirror surfaces, so that the propagation path of light is changed from one type to a U-type, and thus, each optical assembly is arranged on two sides of the optical platform 3 according to the U-type, and the space in the thickness direction is fully utilized, so that the length size of a compact optical transceiver is reduced, and the length requirement on the optical transceiver is reduced.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
