We report on a chip scale parametric amplifier based on a GaInP photonic crystal waveguide. The amplifier operates with both pump and signal in the 1550 nm wavelength range and offers an on-chip gain of 11 dB (5 dB including the 6 dB coupling losses) when pumped at only 800 mW. It enables us, therefore, to incorporate the many advantages of parametric amplification within photonic chips for optical communication applications.
我们报告了一种基于 GaInP 光子晶体波导的片上参量放大器。该放大器在 1550nm 波长范围内同时使用泵浦光和信号光工作，当仅以 800mW 的功率泵浦时，在芯片上提供 11dB 的增益（包括 6dB 耦合损耗在内为 5dB）。因此，它使我们能够在光子芯片中集成参量放大的许多优点，用于光通信应用。
