Integrated diode lasers for the generation of sub-GHz repetition rate frequency combs
Anzal Memon, Albert van Rees, Jesse Mak +4
We demonstrate absorber-free passive and hybrid mode-locking at sub-GHz repetition rates using a hybrid integrated extended cavity diode laser around 1550 nm. The laser is based on…
