Toward integrated tantalum pentoxide optical parametric oscillators

Optics 2023-10-13 v1

Abstract

We present a hybrid waveguide-fiber optical parametric oscillator (OPO) exploiting degenerate four-wave mixing in tantalum pentoxide. The OPO, pumped with ultrashort pulses at 1.55 μ\mum wavelength, generated tunable idler pulses with up to 4.1 pJ energy tunable between 1.63 μ\mum and 1.68 μ\mum center wavelength. An upper bound for the total tolerable cavity loss of 32 dB was found, rendering a chip-integrated OPO feasible as a compact and robust light source.
