Semiconductor Laser White Noise Suppression by Optical Filtering with Ultra-Narrowband FBG
Semiconductor lasers Fiber Bragg gratings
2015/5/21
The white frequency noise of semiconductor lasers is attenuated significantly by optical filtering with an ultra-narrowband fiber Bragg grating. This noise reduction will improve carrier phase estimat...
Suppression of SBS in a photonic crystal fiber with periodically-varied core diameter
Suppression SBS photonic crystal fiber periodically-varied core diameter
2015/5/20
We experimentally demonstrate 7dB improvement in Brillouin suppression in a photonic crystal fiber by periodically varying the size of the air-hole-structure by only 7% amplitude while keeping a low a...
Simple suppression technique for higher-order mode amplification in bent large mode area triple-cladding fibers
Fiber design fabrication iber properties
2015/6/4
A novel technique to suppress the higher-order mode in bent LMA triple-cladding fibers is proposed. It is shown that the higher-order mode can be coupled to a cladding mode with only an adjustment of ...
Solid low-bend-loss transmission fibers using resonant suppression of higher-order modes
transmission fibers resonant suppression higher-order modes
2015/7/30
Ring-assisted fibers suppress unwanted modes, improving the tradeoff that limits bend loss. Fabricated fibers achieve low bend loss and compatibility with standard fibers required for fiber to the hom...
