Single section quantum dash (QDash) mode locked lasers (MLL) can provide a flat and broadband optical frequency comb with low energy consumption, operational simplicity and large-scale low-cost pro…
Single-wavelength fiber ring lasers are demonstrated using rare earth-doped, double-peanut fiber interferometers (RDDPFIs) as the tunable narrow-band filters. With the relatively stronger opto-ther…
