Description
We propose development of Photonic-Integrated Scalable-Trimming for Optical Networks (PISTON), a platform for the adjustment of optical phase-delays in optical-phased arrays (OPAs) and other photonic integrated circuits (PICs). The PISTON platform uses patterned GeSe3 films on SiN optical waveguides for low-loss, non-volatile phase delay adjustment that is compatible with the 700–900 nm wavelength range. We will address phase trimming elements using a scanning confocal microscope in a one-time adjustment during or before PIC packaging. Our approach can be integrated into a foundry CMOS-photonics process, providing a path toward cost-effective phase trimming of PICs for a wide variety of applications.
