Laser phase and frequency noise measurement by Michelson interferometer composed of a 3 × 3 optical fiber coupler.
TL;DR: A laser phase and frequency noise measurement method by an unbalanced Michelson interferometer composed of a 3 × 3 optical fiber coupler is proposed and obtains the noise features of a narrow linewidth laser conveniently without any specific assumptions or noise models.

TL;DR: A commercial distributed feedback diode laser is self-injection locked to the resonance transmission peaks of a fiber Bragg grating Fabry-Perot cavity through a polarization-maintaining fiber ring with the optical path length of 4 m, suitable for advanced applications requiring a narrow linewidth laser with ultralow frequency noise.
Journal ArticleDOI
Precision and broadband frequency swept laser source based on high-order modulation-sideband injection-locking.
TL;DR: A precision and broadband laser frequency swept technique is experimentally demonstrated, using synchronous current compensation to dynamically injection-locked to a specific high-order modulation-sideband of a narrow-linewidth master laser modulated by an electro-optic modulator.
Journal ArticleDOI
Fast optical frequency sweeping using voltage controlled oscillator driven single sideband modulation combined with injection locking.
TL;DR: An ultrafast optical frequency sweeping technique for narrow linewidth lasers is reported that exploits the large frequency modulation bandwidth of a wideband voltage controlled oscillator (VCO) and a high speed electro-optic dual parallel Mach-Zehnder modulator (DPMZM).
Journal ArticleDOI
Research on tunable local laser used in ground-to-satellite coherent laser communication
TL;DR: In this paper, a local laser based on modulation-sideband injection locking is proposed to realize homodyne reception and Doppler frequency shift tracking in ground-to-satellite coherent laser communication.
