Title: Giovanni Barbarossa: Innovator in Optical Communications
Introduction
Giovanni Barbarossa is a notable inventor based in Tucker, GA (US), recognized for his contributions to optical communications technology. With a total of 3 patents, Barbarossa has made significant advancements in the field, particularly in the design and functionality of optical devices.
Latest Patents
One of his latest patents is the "Waveguide grating router employing transmissive Echelle gratings." This invention describes an optical router that utilizes a pair of transmissive Echelle gratings coupled by a waveguide grating. This innovative arrangement allows for substantial design freedom, as it includes various dispersive parameters such as the shapes of the Echelle gratings and the path length differences among the waveguides. Notably, this device eliminates the need for reflective surfaces in the Echelle gratings.
Another significant patent is the "Optical device having modified transmission characteristics by localized thermal treatment." This invention modifies the transmission characteristics of an optical device made from multiple layers of silica-based glass on a silicon substrate through localized thermal treatment. By using a carbon-dioxide (CO2) laser, the core and/or cladding material of a waveguide structure can be selectively softened, which alleviates strain and reduces birefringence. The CO2 laser can also be operated at different power levels to modify the index of refraction, thereby changing the speed of light through the waveguide and affecting the phase shift associated with it.
