[0061] Please refer to Figure 4A and Figure 4B , which respectively show a schematic cross-sectional view of the photoelectric module 100 according to an embodiment. The photoelectric module 100 includes a first substrate 110 , a photoelectric conversion element 120 , an optical waveguide layer 130 and a light guiding element 140 . The photoelectric conversion element 120 is, for example, disposed on the electrode 121 of the first substrate 110 in a flip-chip manner and opposite to the reflective surface 112 for transmitting or receiving an optical signal L. Referring to FIG. Wherein, the reflective surface 112 is an inclined surface, which can reflect the optical signal L at the transmitting end to the light guide element 140 through the reflective surface 112 , so as to transmit the optical signal L to the receiving end through the optical waveguide layer 130 and the light guide element 140 . Similarly, the photoelectric module at the receiving end can also use the above...

[0068] Next, please refer to Figure 5A and Figure 5B , which shows a schematic diagram of a photoelectric module 101 according to another embodiment of the present invention. Similarly, this embodiment utilizes the first groove 113 and the second groove 115 of the stepped groove structure 111 described above, so that the center position of the optical waveguide layer 130 and the center position of the light guide element 140 correspond to each other, and also That is to say, the light waveguide layer 130 is aligned with or matched with the core 141 at the center of the light guide element 140 so that the height H of the center of the light waveguide layer 130 and the center of the light guide element 140 is substantially equal. The same elements are denoted by the same symbols and will not be described in detail here.
[0069] The only difference between this embodiment and the above embodiments is that the photoelectric conversion element 120 is disposed on a second subst...

[0071] Next, please refer to Figure 6 , which is a schematic diagram of a photoelectric module 102 according to another embodiment of the present invention. This embodiment also uses the first groove 113 and the second groove 115 of the above-mentioned stepped groove structure 111 to make the center position of the optical waveguide layer 130 correspond to the center position of the light guide element 140, that is to say The light waveguide layer 130 is aligned or matched with the core 141 at the center of the light guide element 140 , so that the height H of the center of the light waveguide layer 130 is substantially equal to the center of the light guide element 140 . The same elements are denoted by the same symbols and will not be described in detail here.
[0072] The difference between this embodiment and the above embodiments is that: the photoelectric module 102 includes a coating layer 134, which is formed in a groove 111' of a predetermined depth in the first sub...
