Abstract :
The presented VCSELs demonstrate the possibility of fabricating cavities with extremely large Q-factors by using InP/air-gap DBRs. At the same time, the deployed technologies permits to fabricate potentially tunable VCSELs. Photo-pumped and electrically pumped VCSELs and their tunability when working as resonant cavity light emitting diodes are presented. Output powers of up to 110 μW at room temperature and a maximum wavelength tuning of 22 nm have been achieved.
