Abstract

We report on the design and experimental evaluation of AlGaInAs/InP multi-quantum-well epi-structures for mode-locked emission at 1.5-μm. We show that mode-locked lasers fabricated on an optimized 3 quantum-well active region with a low optical confinement factor deliver pulses with increased peak power and stability over a much wider biasing range than those fabricated using a standard 5 quantum well design. Sonogram measurements indicate that sub-ps symmetrical pulses with a substantially reduced linear blue chirp are generated up to nearly three times the laser current threshold.
