Abstract

In this paper we report the generation of narrow line-width laser from a laser diode (LD) by using a fiber Bragg grating (FBG). When slipping an FBG onto the pigtail of the LD, the spectral line width becomes narrower (only including a single longitudinal mode). And the spectral bandwidth is below 0.2 nm. The corresponding intensity with a side-mode-suppression ratio (SMSR) of about 22 dB is observed. In addition, tuning the reflection wavelengths of the FBG, we can get a serial of single mode laser with wavelength spacing 0.94 nm (the tuning range about 10 nm). The spectral widths of lasers at different wavelengths are almost the same.
