| Abstract: | Tunable wavelength lasers are generated by using a laser diode (LD) with a fiber Bragggrating (FBG).The spectral characteristics of different feedback rates have been investigated.Wavelength tuning has been realized by applying compressive and tensile strain to the fiber grating and a tuning range of 10nm has been obtained.The serial of single mode lasers with wavelength spacing 0.94nm has <0.2nm spectral line width and about 35dB side mode suppression ratio.Both the wavelength and power of lasers are stable. |
