Active submicrometer-wavelength silicon (Si) integrated photonics platform
NINT is developing an active submicrometer-wavelength silicon (Si) integrated photonics platform. Our platform leverages the broadband optical transparency of silicon nitride (SiN) to achieve submicrometer-wavelength operation (λ=400-1000nm), and advanced passive functions are enabled by multiple waveguide layers. Demonstrated active functionalities include efficient optical switches, waveguide-coupled photodetectors, and microelectromechanical systems (MEMS) beam scanners. In collaboration with our photonics foundry partner, Advanced Micro Foundry (AMF), our Si photonics platform is fabricated on 200-mm wafers. Packaged photonic integrated circuits (PICs) are being developed for 3D-sensing, microdisplays, spectroscopy, and biosensing. With each generation of our platform, we aim to integrate additional active functions – toward a fully-active, versatile, mass-manufacturable Si photonics platform addressing a multitude of submicrometer-wavelength applications.
