Embodiment Construction

[0012] The following description is to illustrate its functions, and does not limit the composition of the optoelectronic components. For ease of illustration, some common elements are simplified or not illustrated.

[0013] Such as figure 2 , image 3 As shown, the TO-CAN structural assembly is composed of the following parts: laser diode 10, photodetector 30, substrate 40, leads 50, optical silicon platform (SiOB) 100, and also includes RF matching resistor 103, 50Ω characteristic impedance circuit 104 and 105 , the spiral thin film coil 102 and the choke coil 106 .

[0014] The optical silicon platform 100 has a V-shaped groove 101 , which constitutes an intermediate substrate, and is glued on the heat sink 60 , and the heat sink is perpendicular to the TO substrate 40 . The optical silicon platform 100 is conductively connected to the lead wire 50, and the conductive connection is realized through conductive resin or solder such as InSn, PbSn. Wire bonding produces a ...

Description

Technical field: [0001] The invention relates to a photoelectric transmission TO-CAN component, in particular to a high-speed broadband (10GHz) photoelectric transmission TO-CAN component. Background technique: [0002] In the process of modern communication, it is required to transmit a large amount of information and a fast transmission rate. At present, a large number of photoelectric transmission methods are used, and in photoelectric transmission, photoelectric transmission components are necessary devices, and most of the photoelectric transmission TO- CAN components, figure 1 It is a traditional TO-CAN optoelectronic component. Due to the lack of RF compensation and long lead wires, it is generally limited to use within 1 to 2GHz, and cannot be used in high-speed fields such as 10GHz. Invention content: [0003] The purpose of the present invention is to provide a high-speed broadband optoelectronic transmission TO-CAN assembly for the defects of low transmission f...
