Antimonide semiconductor saturable absorber for mode locking of a 1.5-/spl mu/m Er:Yb:glass laser

We demonstrate the first antimonide (AlGaAsSb) semiconductor saturable absorber mirror (SESAM) based on InP and grown by MOVPE. We achieved self-starting and passive mode locking of an Er:Yb:glass laser at 1535 nm and 61 MHz.
