| 英文摘要 | The present invention provides an optical module for light-transmitting a first optical signal with a first wavelength and light-receiving a second optical signal with a second wavelength in bidirectional. The optical module of the invention includes an optical fiber, a laser diode, a photodiode, an optical filter and a holder for securing the optical filter. The laser diode emits the first optical signal, while the photodiode receives the second optical signal. The filter reflects one of the first and second optical signals and transmits the other of first and second optical signals. The holder of the present invention includes first and second lens both built in the surface of the holder. The first lens faces the laser diode and optically couples the laser diode with the optical fiber, while the second lens faces the optical fiber. Since the first and second lenses are built in the surface of the holder, the optical alignment of the laser diode and the photodiode can be automatically carried out by mounting the laser diode and the photodiode on the surface of the holder. |
