Hybrid-mode-family Kerr optical parametric oscillation for robust coherent light generation on chip



Feng Zhou, Xiyuan Lu, Ashutosh Rao, Jordan Stone, Gregory Moille, Edgar Perez, Daron Westly, Kartik Srinivasan


Optical parametric oscillation (OPO) using the third-order nonlinearity (X(3)) in integrated photonics platforms is an emerging approach for coherent light generation, and has shown great promise in achieving broad spectral coverage with small device footprints and at low pump powers. However, current X(3) nanophotonic OPO use pump, signal, and idler modes of the same transverse spatial profile. As a result, such single-mode-family OPO (sOPO) is inherently sensitive in dispersion and can be challenging to scalably fabricate and implement. In this work, we propose using modes of different transverse spatial profiles, which we term as hybrid-mode-family OPO (hOPO), as an alternative, and demonstrate its unprecedented robustness in dispersion versus device geometry, pump frequency, and temperature. Moreover, we show hOPO's capability of emitting a few milliwatts of output signal power at ≈ 8 % power conversion efficiency and without competitive processes. The hOPO scheme is an important counterpoint to existing sOPO approaches, and is particularly promising for robust implementation of coherent on-chip visible and infrared light sources.
