A new approach to spectroscopy of quantum systems using nonlinear integrated photonics

We demonstrate that nanophotonic spectral translation of electro-optic frequency combs is a versatile and compelling approach for addressing high-resolution spectroscopy needs in quantum science and technology.

New results on chip-scale lasers based on nonlinear integrated photonics

In two new papers, we describe how to increase the continuous tuning range of chip-integrated optical parametric oscillators (OPOs) and we demonstrate dense coverage of the so-called 'green gap' spectral region using such OPOs.
