我们提出了一种用于光子任意波形产生的架构，其中12.4 ghz基本锁模外腔半导体激光器的锁相纵向模式被单独调制。我们报道了在37.2 GHz（受光电探测器带宽限制）下，线宽< 100 Hz，动态范围为50 dB的微波音调的光子合成。我们展示了叠加正弦和脉冲RF调制的光子合成12.4 ghz正弦波，展示了利用所提出的架构产生光子任意波形的潜力。
We propose an architecture for photonic arbitrary waveform generation where the phase-locked longitudinal modes of a 12.4-GHz fundamentally modelocked external cavity semiconductor laser are individually modulated. We report photonic synthesis of microwave tones at 37.2 GHz (limited by photodetector bandwidth) with linewidth < 100 Hz and dynamic range 50 dB at 100-Hz resolution bandwidth. We show photonically synthesized 12.4-GHz sine waves with superimposed sinusoidal and pulsed RF modulations, demonstrating the potential for photonic arbitrary waveform generation with the proposed architecture.
