摘要	A dual-ring-modulated laser includes a gain medium (202) having a reflective end coupled to an associated gain-medium reflector and an output end, which is coupled to a reflector circuit through an input waveguide to form a lasing cavity. The reflector circuit comprises: a first ring modulator (216); a second ring modulator (217); and a shared waveguide that optically couples the first and second ring modulators together. The first and second ring modulators have resonance peaks that are tuned to be offset in alignment from each other to provide an effective reflectance having a flat-top response, which is aligned with an associated lasing cavity mode. The first and second ring modulators are driven in tandem based on the same electrical input signal, whereby the resonance peaks of the first and second ring modulators shift wavelengths in the same direction during modulation, and an effective reflectance stays within the flat-top wavelength range.
其他摘要	双环调制激光器包括增益介质（202），该增益介质具有耦合到相关增益介质反射器的反射端和通过输入波导耦合到反射器电路以形成激光谐振腔的输出端。该反射器电路包括：第一环形调制器（216）;第二环形调制器（217）;以及将第一和第二环形调制器光学耦合在一起的共享波导。第一和第二环形调制器具有谐振峰值，所述谐振峰值被调谐成彼此对准地偏移以提供具有平顶响应的有效反射率，该有效反射率与相关激射谐振腔模式对准。基于相同的电输入信号串联驱动第一和第二环形调制器，由此第一和第二环形调制器的谐振峰值在调制期间在相同方向上移动波长，并且有效反射率保持在平顶波长范围内。
