摘要： WDMs have been used to separate a plurality of signals spatially by the difference of wavelengths in prior bidirectional multiwavelength optical communication network. For excluding WDMs, linear PD/LD modules adopt eigen-wavelength photodiodes sensing only the light of an eigen wavelength but allowing all the wavelengths longer than the eigen wavelength. An n-member PD/LD module aligns (n-1) eigen wavelength photodiodes, PD1, PD2, PD3, . . . , PDn-1 of .lambda.1, .lambda.2, .lambda.3, . . . ,.lambda.n-1 and an LD of .lambda. n which satisfy inequalities .lambda.1

摘要： An optical receiver, small and inexpensive, is used for a WDM transmission system in place of a wavelength demultiplexer. In the receiver, a light-transmitting medium and a photodiode (PD) are placed on the same substrate, a wavelength-selecting filter is attached perpendicularly or obliquely to the end face of or to a cut section at the midpoint of the medium, the filter transmits only the assigned wavelength included in the incident light having multiplexed wavelengths, and the PD detects only the assigned wavelength. With an optical fiber, the fiber can be housed in a ferrule. In this case, the filter is inserted into a filter-supporting hole provided at a midpoint of the ferrule, the ferrule is fixed in a groove formed on the substrate, and an optical pathway-changing groove formed on the substrate reflects light having emerged from the optical fiber to introduce it into the PD.

摘要： A photodiode (PD chip) includes a substrate, an absorption layer, a p-n junction in the absorption layer, a passivation film for protecting the end of the p-n junction, a p-electrode, and an n-electrode. The passivation film is covered with a protective layer composed of an insulative resin and having a thickness larger than that of the passivation film such that the passivation film of the PD chip fixed to the Si wafer and hence the p-n junction are not damaged or contaminated when an Si wafer including a number of horizontally and vertically arranged chip units, each having a V-groove for fixing an optical fiber, a marker, and a metallized pattern, is diced. Thus, a low-cost optical receiver module that does not generate dark current can be produced.

摘要： In a surface-mounted optical receiver module comprising a substrate, a photodiode serving as a light receiving device for converting an optical signal into an electrical signal, an optical waveguide serving as an optical transmission line for transmitting the optical signal to the photodiode, and an amplifier device for amplifying the electrical signals, the amplifier device is placed at a predetermined position on the upper surface of the optical waveguide element, which is on the same side as an optical waveguide (on the upstream side in the optical-signal transmitting direction) relative to the photodiode. This configuration eliminates the necessity of additionally securing a space to provide the amplifier device, whereby the size of the optical transmission module can be reduced, and this allows the optical receiver module to receive optical signals at high speed.

摘要： An optical communication device (an LD module or an LD/PD module) having a flat substrate, a light waveguide layer formed upon the substrate with a core for guiding signal LD light, an LD bonded upon a part of the substrate without the whole or a part of the light waveguide layer for producing signal front light and monitoring rear light, a path conversion groove being perforated along the core on the substrate behind the LD and having slanting walls for reflecting rear light emitted backward from the LD, a bottom- or top-incidence type PD bonded upon the light waveguide layer over the path conversion groove for monitoring the LD power by detecting the LD rear light reflected by the path conversion groove. Since the PD level is higher than the LD by the thickness of the light waveguide layer, the monitoring PD can sense more than 50% of the LD rear light.

摘要： A multichannel parallel LD/PD module comprising a bench, a plurality of lightpaths having an initial narrow width region, an intermediate width enlarging region and a final wide width region, a plurality of photodiodes or a photodiode array mounted on the narrow width region, a wavelength selective filter formed on the narrow width region for selectively reflecting receiving beams, a plurality of light emitting devices fitted behind rear ends of the lightpaths on the bench. Traveling in element fibers in an outer ribbon fiber, receiving signal beams go into the lightpaths via front ends and are reflected by the wavelength selective filter slantingly upward at the narrow width region. The reflected beams go into the photodiodes and are converted into photocurrents in proportion to the receiving signals. Emanating from the light emitting devices, transmitting signal beams enter the lightpaths via final ends of the wide width region, propagate backward in the width enlarging region, arrive at the narrow width region, transfer to outer element fibers in a connector, and propagate in the ribbon fiber following the connector. Long distances between the transmitting portion (LDs or LEDs) and the receiving portion (PDs) suppress optical, electromagnetic and electric crosstalk between the light emitting devices and the photodiodes.
