Semiconductor Optical Amplifier Pattern Effect Suppression Using a Birefringent Fiber Loop [PDF]
IEEE Photonics Technology Letters, 2010 The capability of a birefringent fiber loop to suppress the pattern effect in a semiconductor optical amplifier is experimentally demonstrated. The results verify that compared to direct signal amplification this scheme achieves reduced amplitude modulation, enhanced eye diagram extinction ratio, pulse reshaping, tolerance to long string of spaces, low

High-birefringence fiber loop mirror sensor using a WDM fused fiber coupler
Optics Letters, 2013 An intensity-based highly birefringent (Hi-Bi) fiber loop mirror (FLM) sensor is proposed which uses a wavelength-division multiplexing (WDM) fiber coupler. The effect of integrating the WDM coupler in a FLM configuration is first studied. A section of Hi-Bi (bow-tie) fiber of length 0.26 m is then placed in the fiber loop, making the spectral response

High-Birefringent Fiber Loop Mirror Sensors: New Developments [PDF]
, 2012 The fiber loop mirror based on a ring configuration is one of the devices in optical fibers most used in communications and sensors (Mortimore, 1988). The device is formed when the two output ports of a directional coupler are spliced. In this configuration, the two waves at the coupler outputs travel in opposite directions but following the same ...
