"Nonlinear integrated photonics for deployable clocks and quantum sensors" Speaker: Kartik Srinivasan, JQI & NIST Abstract: "The deployment of photonic quantum technologies outside of laboratories and into application environments involves new components and system architectures, many of which are based on photonic integrated circuits (PICs). In this talk, I will present our lab’s research on PIC components that harness nonlinear optical processes in the context of optical atomic clocks and quantum sensors. For such applications, nonlinear frequency conversion can generate the coherent visible and short near-infrared light needed to probe atomic transitions and create a frequency comb that phase-coherently divides an atomically-stabilized optical frequency down to a detectable microwave frequency. I will present results on microresonator optical parametric oscillators operating across the visible and octave-spanning microresonator frequency combs suitable for optical clockworks, and discuss opportunities and challenges associated with building systems based on these technologies."
