    摘要: A method of making a holographic light guide comprising, in sequence, a substrate, a light guiding layer and a holographic recording layer that partially replaces the light guiding layer is disclosed. The substrate is made of a first bismuth sillenite group substance. The light guiding layer is made of a second bismuth sillenite group substance that has a higher refractive index than the first bismuth sillenite group substance and absorbs little of the light being guided. The holographic recording layer is made of a third bismuth sillenite group substance that has a higher refractive index than the first bismuth sillenite group substance and has a degree of photosensitivity.

    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 jointing holder for an optical module for single-fiber bidirectional communication comprises a unitarily structured cylindrical body that has the following portions: (a) an optical fiber-fixing portion for securely holding an optical fiber for transmitting multiwavelength light bidirectionally, (b) a semiconductor laser-fixing portion for securely holding a semiconductor laser for emitting outgoing light λ1, (c) a photodiode-fixing portion for securely holding a photodiode for receiving incoming light λ2, (d) an optical path-forming space for optically coupling the optical fiber, the semiconductor laser, and the photodiode, and (e) in the optical path-forming space, an optical filter-fixing face for securely holding an optical filter for separating multiplexed wavelengths. The jointing holder enables the optical module to reduce the number of components, to be miniaturized, and to reduce the dimensional deviation at the time of the assembly, enabling high-precision assembly. An optical module for single-fiber bidirectional communication incorporates the jointing holder.

    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
