Johnson Bertrand H A chemical etch to turn a clear glass surface translucent. Improves adhesion of metal layers, can be used to diffuse light or for decorative patterns. To prevent unwanted reflections off the end of an optical fiber, the ends are often polished at an angle- which is slow and unreproducible. This patent describes a way to cleave fibers at an angle, obtaining the same optical effect but with dramatically improved quality and reduced cost. Grimes Gary J A multifiber, plastic splitter to combine signals from many sources and passively redistribute those signals.
Design insure low loss, well mixed combination of signals.
Simple, robust construction with low optical losses. It uses waveguides to couple lasers, fibers and photoconductors into a hybrid optical device. A second silicon member forms a sealing lid. Secondary functions included testing, maintenance, fault recovery, etc. Groove is designed to accept the bare glass fiber at one end, and the plastic coated fiber at the other for strain relief.
