Multiwavelength Lasers Based on Semiconductor Optical Amplifiers
IEEE PHOTONICS TECHNOLOGY LETTERS, VOL. 14, NO.5, MAY 2002，-0001，（）：
Stable multiwavelength lasing is demonstrated with a novel laser, in which a semiconductor optical amplifier offers optical gain and cascaded sampled fiber gratings serve as a comb filter. Five lasing lines are obtained with a fixed wavelength spacing of 0.8 nm. Optical power fluctuations among the lasing lines are improved by adjusting reflectivity profile through the cascade of two sampled gratings.
