Description
Technical field
The present invention relates to the hollow packaged type transmitter module in a kind of bi-directional optical transceiver module, relate in particular to a kind of sensitive surface side at this luminescence component, encapsulate a matrix snoot, with a branch of optical fiber of the beam condenser ground directive that this luminescence component is emitted inlet, and prevent the emitted light beam of this luminescence component once more fold back postback optical assembly.
Background technology
Be applied to transmitted in both directions optical transmitting and receiving module at present, as United States Patent (USP) the 6th, 188, shown in No. 495 (OPTICAL TRANSMISSION-RECEPTION APPARATUS0), in the module that is disclosed, mainly contain a branch of optical fiber 11, a luminescence component 3, a reflector plate 6 and a light-receiving module 4, and between this optical fiber 11 and light-receiving module 4, can install lens 8, the inlet of this reflector plate 6 beam reflection ground directive optical fiber 11 that luminescence component 3 can be produced wherein, and this light-receiving module 4 of refraction of optical beam ground directive that is penetrated by optical fiber 11 outwards can be exported to convert electric signal to.Said structure though can output beam and input beam be reflected to diverse location respectively via the reflection of this reflector plate, reaches the purpose of transmitted in both directions, yet has following shortcoming:
1, luminescence component 3 and light-receiving module 4 must install on diverse location, are installing very trouble, have increased and have made difficulty.
2, in order to the reflector plate 6 of deflecting light beams, owing to very accurate, so unit price is also very expensive, causes the cost of product to heighten, and is difficult to generally be accepted by market.
3, because must therefore install with the refraction of optical beam to certain tram, the relevant position of each assembly also must be very accurate, thereby increased the difficulty of making, and product children yield can't effectively be improved, and show its shortcoming.
In view of this this case inventor studies, and discloses a kind of hollow packaged type transmitter module with matrix snoot that is applied in the bi-directional optical transceiver module finally.
Summary of the invention
The object of the present invention is to provide the hollow packaged type transmitter module in a kind of bi-directional optical transceiver module, it comprises: a light-receiving module; A luminescence component is packaged on this light-receiving module; And matrix snoot, system is from the printing opacity material, contain a dish portion, bridge in the periphery of this luminescence component, and being arranged with a recess in the bottom surface of this dish portion, this recess slightly is the hemisphere face shape, to be nested with this luminescence component identically, thereby a branch of optical fiber of the beam condenser ground directive that this luminescence component is emitted inlet, and prevent the emitted light beam of this luminescence component once more fold back postback optical assembly.
Feasible embodiment shown in the present can obtain distinct elaboration by following explanation and accompanying drawing.

Embodiment
As shown in Figure 1 to Figure 3, the present invention relates to the hollow packaged type transmitter module 100 in a kind of bi-directional optical transceiver module, it comprises: a light-receiving module 1; A luminescence component 2 is packaged on the sensitive surface 11 of this light-receiving module 1; And matrix snoot 3, system is from the printing opacity material, containing a dish portion 31 bridges in the periphery of this luminescence component 2, and be arranged with a recess 32 in the center bottom of this dish portion 31, this recess 32 is the hemisphere face shape, being nested with this luminescence component 2 identically, thus the inlet 41 of a branch of optical fiber 4 of light beam L2 optically focused ground directive that this luminescence component 2 is emitted, and prevent the emitted light beam L2 of this luminescence component 2 once more fold back postback optical assembly 2.
Above-mentioned this light-receiving module 1 can be a photodiode (PD:Photodiode), after this photodiode is subjected to illumination, make the Electron absorption luminous energy in the covalent bond and break away from, produce free electron and electric charge carrier, the backward current that this photodiode is produced increases with the increase that absorbs luminous energy, to produce different output signals, outwards export from a terminal 12.And the luminescence component 2 desirable self-luminous diode (LED)s of device on light-receiving module 1, the present invention also will not be from limit.
As shown in Figure 1 and Figure 2, disclosed matrix snoot 3 can be made transparent material such as glass, plastics freely, and the present invention also will not be from limit.The recess 32 of this matrix snoot 3 has a central axial line 30, these central axial line 30 projections align the central authorities of this luminescence component 2, and projection is aligned with the inlet 41 of a branch of optical fiber 4, outside when luminous through triggering when luminescence component 2, its light beam L2 can be by the inlet 41 of these recess 32 optically focused ground directive optical fiber 4.
Because the hollow packaged type transmitter module 100 in the disclosed bi-directional optical transceiver module, wherein this luminescence component 2 is because of being subjected to the shielding of matrix snoot 3, and the interference that significantly reduces reverberation and caused, therefore the present invention can be with these hollow packaged type transmitter module 100 on-line equipments over against optical fiber 4 places on using, make directly directive light-receiving module 1 of light beam L1 that this optical fiber 4 imported, and the also direct inlet 41 of directive optical fiber 4 of the light beam L2 that luminescence component 2 is throwed, promptly between this optical fiber 4 and light-receiving module 1 and light-receiving module 2, must not install water chestnut mirror or deflecting plate again additional, to import with output beam and refract to diverse location respectively, make the photoelectricity receiver module on making, can save the very part of costliness of unit prices such as water chestnut mirror or refracting plates, so that use the manufacturing cost of bi-directional optical transceiver module of the present invention significantly to reduce.
Disclosed hollow packaged type transmitter module 100, can be as shown in Figure 3, application implementation is in a bi-directional optical transceiver module, disclosed hollow packaged type transmitter module 100 devices are at first end of a body 5, second end of this body 5 connects a branch of optical fiber 4 with a connector 51, the central axial line 30 of the recess 32 of this matrix snoot 3 of inlet 41 axial alignment of this optical fiber 4 simultaneously, thereby when this optical fiber 4 behind outgoing beam L1 of the present invention, this light beam can pass this light-receiving module 1 of dish portion 31 directives of matrix snoot 3, to be converted to an electric signal, outwards export from a terminal 12, and after triggering this luminescence component 2, light beam L2 from luminescence component 2 ejaculations, can be by the recess 32 of this matrix snoot 3, the inlet 41 of this optical fiber 4 of directive with along the outside signal of output of this optical fiber 4, and is two-way (Duplex) optical transmitting and receiving module.
Hollow packaged type transmitter module in the disclosed bi-directional optical transceiver module can be applicable to as digital camera, video camera, network etc. in the transmission of audio-visual or signal, and the present invention of its range of application also will not be from limit.
