Half-wave plates in arm waveguides compensate for birefringence, eliminating polarization dependence across the wavelength band.
Photonic integrated circuit with geometrically arranged active and passive regions reduces fabrication complexity while increasing chip yield.
Hollow-core waveguides reduce resistance losses and accelerate signal propagation by replacing dielectric materials with air-filled paths.
A photonic resonant motor converts optical power into mechanical torque using coupled optical resonators and radiation pressure.
A waveguide crossing structure uses a vertically displaced intermediary layer to transfer optical signals between intersecting guides.
Tuned reflector recirculates optical signals through waveguide photodetectors to boost responsivity.
A resin buffer layer between the modulation electrode and substrate reduces mechanical stress on the optical modulator.
