Latest Patents

Tsui is credited with 1 patent: “Multi-tiered Semiconductor Waveguide and Multi-tiered Waveguide Heater.” The patent describes an integrated chip with a semiconductor waveguide formed in two tiers above a base dielectric layer. The first waveguide tier is narrower and positioned higher than the wider second tier. A cladding layer covers the waveguide, while a multi-tiered conductive heater sits above it. The heater includes a tier over the first waveguide tier and two additional tiers positioned over the second waveguide tier, on opposite sides of the first tier. This arrangement integrates waveguide and heater structures within a compact chip design.
