nonlinear optics silicon nitride optical parametric oscillator
Project description

Compact, energy efficient and low cost wavelength tunable lasers are of key interest in spectroscopic sensing applications. Unfortunately, up to today there are no technical solutions to make them. In this project we will use advanced symmetry breaking mechanisms to enable second-order nonlinear effects in CMOS-compatible materials. This may allow the realization of an on-chip tunable optical parametric oscillator.
