Fiber Based Multiple-Access Optical Frequency Dissemination [PDF]
, 2013 We demonstrate a fiber based multiple-access optical frequency dissemination scheme. Without using any additional laser sources, we reproduce the stable disseminated frequency at an arbitrary point of fiber link. Relative frequency stability of 3E10^{-16}

Optimal coupling of entangled photons into single-mode optical fibers [PDF]
Optics Express, 12, 3264-3269 (2004), 2004 We present a consistent multimode theory that describes the coupling of single photons generated by collinear Type-I parametric down-conversion into single-mode optical fibers. We have calculated an analytic expression for the fiber diameter which maximizes the pair photon count rate.

Fiber-Optic Chemical Sensors and Fiber-Optic Bio-Sensors [PDF]
Sensors, 2015 This review summarizes principles and current stage of development of fiber-optic chemical sensors (FOCS) and biosensors (FOBS). Fiber optic sensor (FOS) systems use the ability of optical fibers (OF) to guide the light in the spectral range from ultraviolet (UV) (180 nm) up to middle infrared (IR) (10 μm) and modulation of guided light by the ...
