Integrated sensing and communications using external cavity laser with laser frequency comb
We propose phase-based vibration sensing using external cavity lasers and frequency combs at coherent transmitters and receivers. Digital signal processing(DSP) eliminates laser phase noise recovered from multiple channels and enables small vibration detection. © 2025 The Author(s)
