摘要	An optical transmitter includes a reflective semiconductor optical amplifier (RSOA) coupled to an input end of a first optical waveguide. An end of the first optical waveguide provides a transmitter output for the optical transmitter. Moreover, a section of the first optical waveguide between the input end and the output end is optically coupled to a ring modulator that modulates an optical signal based on an electrical input signal. A passive ring filter (or a 1×N silicon-photonic switch and a bank of band reflectors) is connected to provide a mirror that reflects light received from the second optical waveguide back toward the RSOA to form a lasing cavity. Moreover, the ring modulator and the passive ring filter have different sizes, which causes a Vernier effect that provides a large wavelength tuning range for the lasing cavity in response to tuning the ring modulator and the passive ring filter.
其他摘要	光发射器包括耦合到第一光波导的输入端的反射半导体光放大器（RSOA）。第一光波导的一端为光发射器提供发射器输出。此外，输入端和输出端之间的第一光波导的一部分光学耦合到环形调制器，环形调制器基于电输入信号调制光信号。无源环形滤波器（或1×N硅光子开关和一组带反射器）被连接以提供镜子，该镜子将从第二光波导接收的光反射回RSOA以形成激光腔。此外，环形调制器和无源环形滤波器具有不同的尺寸，这引起游标效应，其响应于调谐环形调制器和无源环形滤波器而为激光腔提供大的波长调谐范围。
