Integrated Optical Phase Shifter Using Buried Electrodes
Published Patent Application Number: 18/902,229
Problem
Efficiently incorporating thermo-optic phase shifters into air-clad integrated photonics.
Invention
We demonstrate the use of a buried heater layout for thermo-optic tuning of integrated photonic devices. Our method places heater electrodes underneath the photonic device layer, rather than the traditional approaches of placing electrodes on the sides of air-clad devices or on top of fully clad devices. This approach is particularly useful in applications requiring air-clad photonic elements and is compatible with all the high-temperature processing required for integrated photonic devices.
Potential Commercial Applications
Applications in areas such as optical communications, optical sensors, integrated photonics, atomic clocks, and quantum computing.
Competitive Advantage
Placing heaters underneath the photonic device layer allows for more flexibility in the device layout, easier integration into air-clad geometries, and more efficient heating.
