We demonstrate a high-performance optical arbitrary waveform shaper based on a single 10 GHz arrayed-waveguide grating with 64 loopback waveguides and integrated amplitude and phase modulators on each waveguide. The design is compact and self-aligning and allows for bidirectional operation. The device's complex transfer function is manipulated and measured over the full 640 GHz passband. To demonstrate optical arbitrary waveform shaping, high-fidelity 15-line shaped waveforms are measured with cross-correlation frequency-resolved optical gating.
我们展示了一种基于单个10 GHz阵列波导光栅的高性能光学任意波形整形器，该光栅具有64个回送波导，并且在每个波导上集成了幅度和相位调制器。该设计紧凑且自对准，支持双向操作。在整个640 GHz通带上对该器件的复传递函数进行了操控和测量。为了演示光学任意波形整形，使用互相关频率分辨光学门控测量了15线的高保真整形波形。
