Abstract
Continuously tunable lasers are desirable for a variety of wavelength division multiplexing (WDM) networks and scientific instruments. Micromechanically tunable vertical cavity surface emitting lasers (VCSEL) have shown potential as a cost-effective, wide tuning source for these applications [1,2]. However, to date such tunable VCSELs had considerably higher threshold currents and lower output powers than conventional VCSELs.
