Latest Patents

Zubrzycki's latest patents include an integrated resonant micro-optical gyroscope and a method of fabrication. This innovative gyroscope is based on a photonic integrated circuit (PIC) that features a bidirectional laser source, optical waveguide phase modulators, and waveguide photodetectors. The PIC connects to a passive ring resonator, which can be formed from either optical fiber or coiled optical waveguide. The design allows for the detection of rotation rates by phase modulating the lasing output and directing it around the resonator in two counterpropagating directions.

Another significant patent is for a highly efficient, electrically pumped edge-emitting semiconductor laser. This laser utilizes a one- or two-dimensional photonic bandgap (PBG) structure to form its optical cavity. The design incorporates PBG mirrors that operate within the photonic band gap regime, achieving transverse confinement through the use of lower-index cladding layers surrounding an active semiconductor layer. The active layer can include a quantum well structure, which enhances the extraction of laser light.
