  • Title: Short-wavelength MEMS-tunable VCSELs.
    Author: Cole GD, Behymer E, Bond TC, Goddard LL.
    Journal: Opt Express; 2008 Sep 29; 16(20):16093-103. PubMed ID: 18825248.
    Abstract:
    We present electrically-injected MEMS-tunable vertical-cavity surface-emitting lasers with emission wavelengths below 800 nm. Operation in this wavelength range, near the oxygen A-band from 760-780 nm, is attractive for absorption-based optical gas sensing. These fully-monolithic devices are based on an oxide-aperture AlGaAs epitaxial structure and incorporate a suspended dielectric Bragg mirror for wavelength tuning. By implementing electrostatic actuation, we demonstrate the potential for tuning rates up to 1 MHz, as well as a wide wavelength tuning range of 30 nm (767-737 nm).
