Journal ArticleDOI
Ultrahigh Scanning Speed Optical Coherence Tomography Using Optical Frequency Comb Generators
TL;DR: In this paper, a novel optical coherence tomography system without any moving parts for depth scanning was proposed and demonstrated using two optical frequency comb generators, as broad-band spectrum generators, instead of moving parts.
Journal ArticleDOI
Absolute frequency measurement of the saturated absorption lines of methane in the 1.66 μm region

TL;DR: In this article, the absolute frequencies of the R(0) and Q(1) transitions of the 2 ν 3 band of 12 CH 4 in the 1.66-μm region were determined.
Journal ArticleDOI
12-THz frequency difference measurements and noise analysis of an optical frequency comb in optical fibers
TL;DR: In this article, a span up to 50 THz of optical frequency comb (OFC) has been obtained by self-phase modulation in an optical fiber by detecting the sidebands offset by up to 12 THz from the carrier.
Journal ArticleDOI
3.17-THz frequency-difference measurement between lasers using two optical frequency combs
TL;DR: In this paper, two laser beams were combined into the optical frequency comb generator (OFC-G), and many sidebands that contribute to the beat signal generation were generated, achieving a signal-to-noise ratio of 30 dB when the frequency difference between two lasers was 3.17 THz.
Journal ArticleDOI
Accurate relative frequency cancellation between two independent lasers
TL;DR: A simple and novel feed-forward method with an acousto-optic modulator that can be used in optical phase-locked loops and accurately stabilized and maintained is described.
