FIBER LOOP MIRROR FILTER WITH TWO-STAGE HIGH BIREFRINGENCE FIBERS [PDF]

open access: yesProgress In Electromagnetics Research C, 2009
A flber loop mirror (FLM) with two-stage high birefrin- gence (Hi-Bi) flbers is theoretically and experimentally studied for var- ious rotation angles and Hi-Bi flber lengths. The experimental spectra are observed to be in good agreement with the theoretical spectra, ver- ifying our theoretical model.

Enhanced performance of semiconductor optical amplifier at high direct modulation speed with birefringent fiber loop

open access: yesAIP Advances, 2014
We employ a birefringent fiber loop (BFL) for enhancing the performance of a semiconductor optical amplifier (SOA) which is directly modulated. By properly exploiting the BFL comb-like spectral response, we show that the SOA can be directly modulated at ...
