Abstract

We demonstrate the first optical parametric oscillator (OPO) based on chalcogenide glass. The parametric gain medium is an As(2)Se(3) chalcogenide microwire coated with a layer of polymer. The doubly-resonant OPO oscillates simultaneously at a Stokes and an anti Stokes wavelength shift of >50 nm from the pump wavelength that lies at λ(P) = 1,552 nm. The oscillator has a peak power threshold of 21.6 dBm and a conversion efficiency of >19%. This OPO experiment provides an additional application of the chalcogenide microwire technology; and considering the transparency of As(2)Se(3) glass extending far in the mid-infrared (mid-IR) wavelengths, the device holds promise for realizing mid-IR OPOs utilizing existing optical sources in the telecommunications wavelength region.

摘要

我们展示了首个基于硫系玻璃的光学参量振荡器（OPO）。参量增益介质是一根涂有一层聚合物的As₂Se₃硫系微丝。双共振OPO在斯托克斯波长和反斯托克斯波长处同时振荡，相对于位于λ(P)=1552nm的泵浦波长，波长偏移大于50nm。该振荡器的峰值功率阈值为21.6dBm，转换效率大于19%。此OPO实验为硫系微丝技术提供了一项新应用；考虑到As₂Se₃玻璃在中远红外（mid-IR）波长范围内具有很宽的透明度，该器件有望利用电信波长区域现有的光源实现中红外OPO。
