Method and system for mode stabilization of VCSELS using increased bias current

摘要

The present invention discloses a vertical cavity surface emitting laser (VCSEL). The VCSEL comprises a first and second mirror stack. The VCSEL has an active region positioned between the first mirror stack and second mirror stack. Also, the VCSEL has a contact region in at least one of the active regions. The VCSEL encompasses a module for stabilizing the gains among a plurality of modes included by spatial power instability by increasing the current through the contact.
