Mode-locking in vertical external-cavity surface-emitting lasers with type-II quantum-well configurations

Research output: Contribution to journalArticle

Abstract

A microscopic study of mode-locked pulse generation is presented for vertical external-cavity surface-emitting lasers utilizing type-II quantum well configurations. The coupled Maxwell semiconductor Bloch equations are solved numerically where the type-II carrier replenishment is modeled via suitably chosen reservoirs. Conditions for stable mode-locked pulses are identified allowing for pulses in the 100 fs range. Design strategies for type-II configurations are proposed that avoid potentially unstable pulse dynamics.
