Fiber-Coupling Efficiency of Laser Array Beam From Turbulent Atmosphere to Fiber Link
Journal of Lightwave Technology, 2023Free-space optical communication (FSOC) systems are nowadays integrated with fiber optical components developed for fiber-optic communications. In such integrated systems, the collected portion of the incident beam on the receiver lens is coupled into a ...

Optical Interconnects XX, 2020
For miniaturized optical fiber coupled MOEMS systems, fiber coupling on chip level is necessary. Therefore a silicon chip based optical fiber coupling with high position accuracy is introduced. In this paper, we present the fiber chip coupling on two examples: A superconducting single photon detector (SSPD) and a miniaturized fiber Bragg grating sensor.

Fiber-coupled multiplexed confocal microscope
Optics Letters, 2000We describe a new parallel scanning mechanism for confocal microscopy that is inherently fiber-optic compatible and that retains the simplicity of the line scanning confocal microscope. The method works by employing an incoherent fiber-optic bundle that maps a line illumination pattern back on itself on double passing, while separating the fibers that ...

Alignment and efficiency-monitoring method of high-power fiber-to-fiber coupling
, 2020High-power fiber-to-fiber coupling is extensively used in fiber laser applications, and its performance is determined by coupling efficiency. We demonstrate a novel method for alignment and monitoring efficiency by detecting backscattering power at the ...

Remote coupling in Bragg fibers
Optics Letters, 2004We propose a remote directional coupler in Bragg fibers that allows for efficient conversion of the fundamental core mode into an annular mode structure over remote distances. We give design guidelines and confirm the results by finite-difference time-domain calculations.

Modal characterization of fiber-to-fiber coupling processes
Optics Letters, 2013We present a detailed experimental investigation of a fiber-to-fiber coupling process by characterizing the mode content at the output of the system. In our experiment a single-mode fiber is transversally scanned with respect to a multimode fiber, revealing position-dependent higher-order mode excitation. The outlined measurement system can be used for

Coupled-cavity erbium-fiber lasers incorporating fiber-grating reflectors
Conference on Optical Fiber Communication, 1993Narrow-linewidth erbium-doped fiber lasers of monolithic multiple linear cavity configurations that use intracore fiber grating reflectors are demonstrated. Robust single-frequency operation of a miniature coupled-cavity fiber laser with a linewidth of 30 kHz is reported.

Applied Physics Letters, 2004
We demonstrate that in fiber-coupled random laser, the threshold energy is twofold reduced and the slope efficiency is fivefold increased when the tip of the fiber is relocated from the surface to the depth of the powder volume. High absorption efficiency, 85%, and high conversion efficiency of population inversion to stimulated emission, 90%, make ...
