Power enhanced and fast swept source for phase conjugate optical coherence tomography

FTuY - Coherence Tomography: Paper FTuY1We have developed a wavelength-swept source based on fiber parametric amplification and Fourier domain mode locking with increased power and speed to take full advantage of 2x resolution enhancement and dispersion cancellation of phase-conjugate OCT.postprintFrontiers in Optics 2010 / Laser Science XXVI (FiO/LS 2010), Rochester, N.Y., 24 October 2010.

Efficient generation of tunable photon pairs at 0.8 and 1.6 micrometer

We demonstrate efficient generation of collinearly propagating, highly nondegenerate photon pairs in a periodically poled lithium niobate cw parametric downconverter with an inferred pair generation rate of 1.4 X 10(7)/s/mW of pump power. Detection of an 800-nm signal photon triggers a thermoelectrically cooled 20%-efficient InGaAs avalanche photodiode for the detection of the 1600-nm conjugate idler photon. Using single-mode fibers as spatial mode filters, we obtain a signal-conditioned idler-detection probability of similar to3.1%. (C) 2002 Optical Society of America.</p
