摘要	An optical amplifier with a flattened wideband response is obtained by coupling counter-propagating pumping energy into an optical waveguide to cause Raman amplification in the optical waveguide, and by reflecting an amplified signal received from the optical waveguide into an output waveguide using a reflector having a spectral characteristic that is complementary to the spectral gain characteristic of the Raman amplification.
其他摘要	通过将反向传播的泵浦能量耦合到光波导中以在光波导中引起拉曼放大，并且通过使用具有反射器的反射器将从光波导接收的放大信号反射到输出波导中，获得具有平坦宽带响应的光放大器。光谱特性与拉曼放大的光谱增益特性互补。
主权项	An optical amplifier comprising: an optical waveguide having a first end and a second end, wherein a signal is received through the first end, is amplified by Raman amplification as it propagates within the optical waveguide from the first end to the second end, and is transmitted through the second end; a pumping energy source optically coupled to the optical waveguide to provide pumping energy that causes the Raman amplification to have a spectral gain characteristic; and a reflector having an input optically coupled to the second end of the optical waveguide and having an output, wherein the reflector receives the amplified signal through the input and reflects it through the output, and wherein the amplified signal is modified by the reflector according to a property that is complementary to the spectral gain characteristic of the Raman amplification.
