Tunable Laser Linewidth Via Phase Wrapping in Optical Phase Random Walk Modulation
A phase wrapping method is proposed to confine FPGA-generated Brownian random walk signals, enabling tunable laser linewidth through phase modulation while effectively mitigating the lowfrequency loss observed in the mirror method.
