Journal ArticleDOI
Self-Stabilization of the Optical Frequencies and the Pulse Repetition Rate in a Coupled Optoelectronic Oscillator
TL;DR: In this paper, a coupled optoelectronic oscillator (COEO) based on a laser with a high finesse intracavity etalon is presented, which produces a 10.24 GHz spaced optical frequency comb by selecting a single optical supermode.
Journal ArticleDOI
Noise Characterization of an Injection-Locked COEO With Long-Term Stabilization
TL;DR: In this paper, a semiconductor-based coupled opto-electronic oscillator using continuous-wave optical injection for the generation of an optical frequency comb with 10.24 GHz spacing is presented.
Journal ArticleDOI
Multiheterodyne Detection for Spectral Compression and Downconversion of Arbitrary Periodic Optical Signals
TL;DR: In this article, the correlation between photodetected white light at different times can generate RF interference that is sensitive to the optical phase, and the analysis is extended to the heterodyning and sampling of bandlimited incoherent light sources.
Journal ArticleDOI
Characterization of Semiconductor-Based Optical Frequency Comb Sources Using Generalized Multiheterodyne Detection
TL;DR: In this paper, a spectrally efficient multiheterodyne scheme is applied for the independent measurement of the spectral phase profiles of three distinct semiconductor frequency combs, and the amount of quadratic and cubic phase is quantified for each source, providing insight on the dispersive properties of the semiconductor gain and the fiberized laser cavity.
Proceedings ArticleDOI
Stabilization of an injection locked harmonically mode-locked laser via polarization spectroscopy for frequency comb generation
TL;DR: Stabilization of an injection-locked optical frequency comb is achieved through polarization spectroscopy of an active laser cavity, eliminating optical PM sidebands inherent in previous stabilization methods as mentioned in this paper, achieving optical SNR of 35 dB.
