We present the applications of a Vernier effect based on cascading two Mach - Zehnder interferometers (MZIs) as a selectable comb filter and saturable absorber (SA) in an erbium -doped fiber laser (EDFL). Each MZI is composed of bi-tapered polarization -maintaining fibers (PMFs) constructed by fusio...
