Optical comb laser

A comb laser is a light source with a spectrum composed of equidistant lines, each line corresponding to a longitudinal cavity mode, but emitting spectral lines with the same modulation frequency. The uniqueness of comb laser lies in its superior time stability of spectral lines.

Ordinary multi frequency semiconductor lasers suffer from mode splitting noise (MPN), which causes significant temporal fluctuations in spectral lines and affects their application in optical communication. The compact single-chip comb shaped laser diode chip is based on InAs/InGaAs quantum dot technology. The relative intensity noise (RIN) of each spectral line in a quantum dot comb laser is low enough to transmit broadband data without errors or signal loss. Due to these characteristics, comb lasers can also serve as low-noise optical generators (OFCs) with high accuracy, which can be used to measure unknown frequencies or adjust lasers to match specific frequencies.

Main characteristics of comb laser:

High stability:The quantum dot comb laser has been optimized to minimize the occurrence and impact of mode hopping, prevent phase jitter and mode segmentation noise. This makes optical frequency comb technology more widely applicable.

high-precision:Quantum dot comb lasers have very high precision in the development and manufacturing process, and can provide high-precision measurements for a long period of time. This ensures precise results and minimizes the need for adjustments.

Low intensity noise:Due to optimized stability and constant power flow, the relative intensity noise of the spectral lines emitted by comb lasers is close to the edge. This is crucial for its use in data communication and telecommunications applications.
