Integrated photonics is making strides towards hosting an increasing range of functionalities on a chip. Examples include information processing and computation as well as optical sensing and ranging applications. This has spurred advances in integrated laser light sources, which are needed for photonic chips to become truly autonomous devices. Thus, on-chip isolation likewise becomes important for suppressing feedback detrimental to their operation.
