摘要： An optical communications module in which electrical crosstalk is reduced. The term “optical communications module” represents a surface-mounting-type optical tranceiver, transmitter, or receiver module. The optical communications module has a following structure. (a) An Si substrate carries at least one signal-transmitting section comprising an LD, at least one signal-receiving section comprising a PD, or both together with other components. (b) An insulating substrate is bonded to the back face of the Si substrate. (c) A separating groove separates the Si substrate along the or each boundary line between the sections in order to prevent an AC current flowing through the Si substrate. To attain this object, the separating groove is provided from the top surface of the Si substrate to some midpoint of the insulating substrate. This structure reduces the electrical crosstalk between the signal-transmitting section and the signal-receiving section, between the signal-transmitting sections, and between the signal-receiving sections.

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 three-storied structure optical communications module having a top case, a middle case and a bottom case which are piled and coupled in a vertical direction. The middle case has a silicon bench with M (channel number) lightwaveguides, a first WDM1, a second WDM2, M (channel number) laser diodes for generating transmitting signals λ1. The top case has a set of λ2 receiving photodiodes PD1s of the channel number M. The bottom case has another set of λ3 receiving photodiodes PD2s. λ2 signal beams and λ3 signal beams propagating in optical fibers go into the lightwaveguides on the middle case. The λ2 signal beams are reflected midway on the lightwaveguides by the WDM1 upward to the photodiodes PD1s on the top case and are converted into photocurrents by the photodiodes PDs. The λ3 signal beams are reflected halfway on the lightwaveguides by the WDM2 downward to the photodiodes PD2s and are converted into photocurrents by the photodiodes PD2s. The λ1 yielded by the laser diodes make their way in the lightwaveguides, go into a multichannel fiber and propagate in the multichannel fiber. The three-storied structure allows two sets of M-channel receiving signals and a set of M-channel transmitting signals to be received or transmitted. The three-storied structure enables the module to alleviate a necessary area and reduce optical, electrical interchannel crosstalk.

摘要： A device including a fiber/waveguide and a optical device (PD, LD or so). The end of an optical fiber or a light waveguide is cut slantingly. A transparent resin of a refractive index akin to the fiber/waveguide encloses the fiber/waveguide, the optical device and a space between them. The slanting end cutting and the transparent resin cooperate with each other to annihilate the reflection, returning light perfectly without reducing the coupling coefficient.
