Abstract:

The primary goal of this fundamental research project was to demonstrate magnet-free on-chip optical isolators, especially near 780 nm wavelength, as these can be important device components in future microsystems based on atomic microsystems technologies. We were successful in developing this new optical isolator using a lithium niobate PIC platform. Instead of magneto-optic materials, this isolator uses an electrical stimulus to piezoelectrically launch acoustic waves through the PIC and produce a non-reciprocal effect. The isolators were proven to operate at both 780 nm and 1550 nm using the same starting substrate, successfully reaching the project goals.
