Abstract

We report on a passively modelocked InP/InGaAsP quantum well semiconductor ring laser which operates at 20GHz repetition rate and at 1.58µm output wavelength. A number of devices with varying relative positions of the absorbers and amplifiers have been realized using active-passive integration technology in the JEPPIX fabrication platform. The 4mm-long laser ring cavity incorporates a 750µm-long optical amplifier section, a separate 40µm-long saturable absorber section, passive waveguide sections and a passive MMI-type 50% output coupler. We investigate operation regimes of the laser and explore conditions for single mode lasing and mode-locked operation.
