The direct correspondence between the noise and the linewidth in an ideal oscillator was first introduced by Schawlow and Townes [ 1 ]. Identification of a linewidth of a laser characterized with a pure white frequency noise spectrum (1/f0) was extended in later works [ 2, 3 ]. The case of the flickering and drifting lasers ...

NettetAPSK is found to offer higher tolerance mm-wave phase noise compared to OFDM, ultimately easing optical linewidth restrictions to ∼30 kHz. The model is extended to include a novel millimetre wave phase noise cancelling receiver, which is shown to significantly alleviate these restrictions even further—enabling phase noise free … NettetWe propose a precision measurement method of laser linewidth based on short-delay self-homodyne, using the second peak-valley difference (SPVD) feature of the coherent power spectrum to fit laser linewidth. The SPVD model of the self-homodyne coherent envelope spectrum was established.
