Abstract: We have proposed and experimentally demonstrated a broadband-adjustable band-rejection filter based on a chirped and tilted fiber Bragg grating (CTFBG). The CTFBG is fabricated using ...

Abstract: We demonstrate a chirped fiber Bragg grating (CFBG) based stretched-pulse mode-locked (SPML) wavelength-swept laser that uses both intra-cavity and post-cavity stretching. The SPML laser ...
