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.

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 standard multichannel optical fiber has a pitch 250 &mgr;m (P1), whereas mounting of optoelectronic device chips can require a pitch P2 larger than P1. The pitch of element fibers should be enlarged for coupling a multichannel ribbon fiber to a multichannel photodiode (PD) or laser diode (LD) module having photodiodes or laser diodes for M channels. The module includes a connector maintaining M fibers with tails extending backward and a bench having M V-grooves aligned at the larger pitch P2 for receiving the tails of the fibers. M light waveguides are aligned at the pitch P2 following the V-grooves. The module also includes M photodiodes or laser diodes following the light waveguides. A package includes the connector at a front part, the fiber tails at a width enlarging region for converging the pitch from P1 to P2, and the bench at a back part.
