Acoustically-driven Near-infrared on-Chip Optical Isolator for photonic Circuits (ANECHOIC)

Laser systems are ubiquitous in high-data rate communication and sensor systems in which unwanted back-reflections from optical components can cause instabilities in the laser spectrum leading to poor system performance or damage to the laser itself. As photonic technologies miniaturize with advancements in photonic integrated circuit (PIC) technology, the development of on-chip optical isolators are of critical importance. To address these issues Physical Sciences Inc. (PSI) will develop an Acoustically driven Near-infrared on-Chip Optical Isolator for photonic Circuits (ANECHOIC) to achieve high optical isolation contrast (IC) in a compact footprint that is able to be incorporated easily into (PIC)-based systems for ultra-sensitive applications in thin-film lithium niobate (TFLN).
