Study on the fiber coupling efficiency for ground-to-satellite laser communication links
SPIE Proceedings, 2010Recently, the amount of the data measured by the satellites becomes increase because the recent satellites have been higher performances. Therefore, the faster communication method is demanded. One of the solutions is to use optical communication systems. When widely available fiber optical devices are used in free-space laser communication systems,

Reflective-refractive microlens for efficient light-emitting-diode-to-fiber coupling
Optical Engineering, 2005We propose a microlens for improving the coupling efficiency between a Lambertian emitter and an optical fiber with small numerical aperture. The nonimaging lens uses refraction in the central part for light rays emitted at small angles, and reflection in the peripheral part for rays emitted at large angles.

Optimization of single-mode fiber coupling efficiency with an adaptive membrane mirror
Optical Engineering, 2002We propose and demonstrate the use of an adaptive membrane mirror to increase the efficiency of coupling light into optical single-mode fibers. The membrane mirror has an active area of 12 mm in diameter and is electrostatically activated by 37 electrodes. Two optimization algorithms are compared.

1.3-μm large spot size laser for efficient fiber coupling
Optical Engineering, 1998Taper and truncation loss calculations, experimental internal reflections, and far-field characteristics and coupling efficiencies into single-mode fiber are reported for a 1.3-?m large spot laser design with laterally tapered active region and a weakly guiding passive waveguide underneath. In the front passive section, the taper is truncated.
