Abstract
Wavelength references in the telecom spectrum have applications in communications and dimensional metrology. However, they typically consist of bulk optics and vapor cells. Photonic integration of these components may lead to low cost, portable devices. Here we demonstrate the incorporation of a photonic Rb spectrometer with an AlN microresonator frequency doubler. Light at 1560 nm is coupled onto a chip containing the AlN microresonator frequency doubler. The resulting 780 nm light is sent to the photonic Rb spectrometer, which consists of an apodized grating beam expander and microfabricated MEMS vapor cell. We perform Doppler broadened spectroscopy of the D2 line and demonstrate preliminary laser stabilization to these features.
