Strictly all-fiber picosecond Ytterbium fiber laser utilizing chirped-fiber-Bragg-gratings for dispersion control [PDF]
, 2008 A compact, strictly all-fiber, picosecond pulse source based on ytterbium (Yb) doped fiber is described. Stable solitary mode-locking is obtained in a fiber-oscillator utilizing a carefully designed chirped fiber-Bragg-grating (C-FBG) for both dispersion control and spectral filtering.

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 ...

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.
