We report first observation of net-gain from an optical parametric amplifier in a planar waveguide. This was achieved in a low-loss As(2)S(3) planar waveguide, with a strong nonlinearity (gamma approximately 10 /W/m) and tailored anomalous dispersion yielding efficient Raman-assisted four-wave mixing at telecom wavelengths. The experiments were in good agreement with theory, and indicate a peak net-gain greater than +16 dB for the signal and idler (+30 dB neglecting coupling losses) and a broad bandwidth spanning 180 nm.
我们首次报道了在平面波导中光学参量放大器实现净增益的观测结果。这是在低损耗的As₂S₃平面波导中实现的，该波导具有很强的非线性（γ约为10 /W/m）以及经过定制的反常色散，从而在电信波长下实现了高效的拉曼辅助四波混频。实验结果与理论高度吻合，表明信号光和闲频光的峰值净增益大于 +16 dB（忽略耦合损耗时为 +30 dB），并且带宽达180 nm。
