Title: Innovations of Robert Edward Smith
Introduction
Robert Edward Smith is a notable inventor based in Albuquerque, NM (US). He has made significant contributions to the field of optical devices, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Tapered rib fiber coupler for semiconductor optical devices." This invention features a monolithic tapered rib waveguide designed to transform the spot size of light between a semiconductor optical device and an optical fiber. The tapered rib waveguide is integrated into the guiding rib atop a cutoff mesa type semiconductor device, such as an expanded mode optical modulator or an expanded mode laser. This design effectively forces the guided light down into the mesa structure of the semiconductor optical device, allowing for coupling losses of 1.0 dB or less.
Another significant patent is the "Cutoff-mesa isolated rib optical waveguide for III-V heterostructure." This invention provides single-mode performance regardless of any deep etches used for electrical isolation between integrated electro-optic devices. By utilizing a principle of a cutoff slab waveguide with an asymmetrical refractive index profile, this design achieves single-mode operation with a wide range of rib widths, eliminating reflection effects and reducing high order mode propagation and crosstalk compared to conventional rib waveguides.
