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.

摘要： The present invention provides an optical receptacle having a superior insertion/extraction performance of the ferrule, and an optical sub-assembly applying the optical receptacle. The optical receptacle 1 includes a stub, a bush 4, a sleeve, and a sleeve cover. The stub having a lower portion covered by the bush, and an upper portion covered by the sleeve. The sleeve may be a rigid sleeve without any slit along the optical axis in its outer surface. The sleeve cover covers the sleeve and the bush. In the present optical receptacle, the bush is press-fitted into the gap formed between the stub and the sleeve cover. Accordingly, in addition to the application of the rigid sleeve, not only the sub is hard to slide out from the sleeve, but also the insertion/extraction performance of the ferrule to be inserted into the sleeve may be enhanced.

摘要： A transmitting and receiving module helps reduce electrical crosstalk and noise during transmitting and/or receiving signals. Electrical isolation among metallized electrodes in a surface-mounted module with an optical fiber and an optical device can be achieved by using a low resistivity Si substrate, providing ground terminals on the surface of the Si substrate, and grounding the Si substrate. Noise and crosstalk during transmitting and receiving signals can be reduced by providing a copper contact adhered to the bottom surface of the Si substrate and by grounding.
