Latest Patents

One of his latest patents is a bi-directional PLC transceiver device. This integrated device is designed for multiple wavelength optical signals, featuring a high level of wavelength isolation at the receivers and low cross-talk of light between an external laser transmitter and the receivers. The invention includes a WDM planar light wave circuit (PLC) assembly that combines high spatial light confinement waveguide structures with a variable thickness dielectric wavelength selective filter (WSF). This allows the device to reflect a first wavelength signal while passing a second wavelength signal. Additionally, the patent describes optical waveguide structures where the light confinement strength varies along the direction of light propagation. These waveguides consist of a core that propagates light along a defined path and a cladding material that partially surrounds the core. By varying the refractive index profile or lateral core dimensions, the degree of light confinement can be tailored, enabling applications such as mode-matching and compact directional couplers.
