Title: The Innovations of Ram Jambunathan
Introduction
Ram Jambunathan is a notable inventor based in Allentown, PA (US). He holds a total of 8 patents that showcase his contributions to the field of technology and engineering. His work primarily focuses on advanced optical devices and electroabsorption modulators.
Latest Patents
One of his latest patents is the "Grating Dispersion Compensator and Method of Manufacture." This invention includes a substrate, a dielectric grating layer, a planar waveguide, and a passivation layer. The dielectric grating layer is formed on the substrate and features a variation in refractive index, which defines a grating period that can vary along the longitudinal axis of the GDC according to a predetermined function. This design allows for the creation of a selected center wavelength and dispersion curve, with the chirp of the grating period controlled by current, voltage, temperature, or pressure. Another significant patent is the "Method of Fabricating a Monolithic Expanded Beam Mode Electroabsorption Modulator." This method involves a waveguide layer with two expansion/contraction sections and an electroabsorption section arranged along a longitudinal axis. The process includes forming a patterned growth retarding layer on the substrate and selectively growing the waveguide layer, which has a different index of refraction than the substrate.
