Stable 100 GHz Pulses Generated by injection locking of multiple lasers to an optical frequency comb

摘要

Optical frequency combs (OFCs) can generate a wide bandwidth of regularly spaced modes with high frequency stability. Besides frequency and time metrology, OFCs can also have applications in arbitrary waveform generation and telecommunications by manipulating individual comb modes. We have previously demonstrated using optical injection locking to selectively amplify individual comb modes which are closely spaced (250 MHz) [1]. Over 50 dB of gain was achieved with low phase noise associated with the locking process [2]. The injection locking process maintains the coherence properties of the master laser and therefore by combining multiple lasers locked to different frequencies of a common OFC, pulses can be generated.
