摘要： A semiconductor photodetector comprising a photodiode chip, a header for mounting the chip, a receptacle, and a ferrule for holding an end of an optical fiber. The photodetector does without a lens. A dielectric layer covers a periphery of the photodiode chip for shielding it from incidence of extra light beams by reflecting or absorbing light. Omission of a lens reduces the costs of parts and assembly. Since no light beams enter the peripheral part of photodiode chip, no delayed photocurrent is produced. Reproduced signals are immune from deformation or delay of phase. The photodetector facilitates wide prevalence of optoelectronic communication.

摘要： A semiconductor light source for transmitting light signals of digital or analog data having a laser diode and a photodiode for monitoring the output power of the laser diode. The driving current of the laser diode is adjusted by the photocurrent of the monitoring photodiode. The photodiode has a light receiving region at a center enclosed by an annular electrode and a light non-receiving region outside the annular electrode. If leak light beams entered the non-receiving region, delayed photocurrent is produced. The delayed photocurrent misleads the control of the laser diode. This invention provides a non-receiving region of the photodiode with a dielectric layer for reflecting or absorbing light beams in order to preventing the light beams from producing the delayed photocurrent.

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.

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： 250 μm is the standardized pitch H of the prevalent multichannel ribbonfibers. Current laser diodes and photodiodes have a size larger than 300 μm. Curving lightpaths made on a silicon bench for reconciling the chip size with current ribbonfibers causes bending power loss, optical crosstalk and difficulty of production. Linear parallel lightpaths with a width d for more than one chip site are produced on a bench with a pitch E which is equal to the pitch H of the multichannels. Optoelectronic device chips with a width W satisfying an inequality E
