摘要： An optical receiver is provided with an optical-signal-receiving section and a controlling section. The optical-signal-receiving section incorporates a photodetector. The photodetector has an APD. Through a passivation film, a photoconductor is placed on a portion of a surface of the APD which remains unoccupied by an optical-signal-receiving area of the APD. When this structure is employed, the signal for controlling the avalanche multiplication factor of the APD can be obtained from the photoconductor. Consequently, the signal can be obtained with a simple structure. Furthermore, the photoconductor has a good linearity of the output current even to a weak lightwave. As a result, the output current I for controlling the avalanche multiplication factor of the APD can be obtained with high accuracy.

摘要： An optical receiver includes a PIN photodiode (PIN-PD) having an incident surface for receiving signal light, the PIN-PD transmitting a part of the signal light to the surface opposite to the incident surface, and an avalanche photodiode (APD) having an incident surface for receiving light transmitted through the PIN-PD. In the optical receiver, the ratio of the quantity of signal light detected by the PIN-PD and the ratio of the quantity of signal light detected by the APD are not affected by the polarization state of the signal light incident on the optical receiver, and accordingly the avalanche multiplication factor of the APD is suitably controlled on the basis of the signal light detected by the PIN-PD.

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.
