Research output: Contribution to journalArticlepeer-review


Single-longitudinal-mode operation of zero-order lateral mode quantum-well GaAs/(AlGa)As Fabry-Perot lasers has been found to occur over a very wide operating current range. Single-longitudinal-mode operation is very stable, typically allowing an increase in optical output power from 0 to Semiconductor lasers, Quantum opticsx003E;20mW/facet before mode-hopping occurs. The mode hop at ~23mW leads to bistable single-longitudinal-mode operation with a very large hysteresis loop.
