Pd. Wang et al., Half-symmetric cavity microelectromechanically tunable vertical cavity surface emitting lasers with single spatial mode operating near 950 nm, APPL PHYS L, 75(7), 1999, pp. 897-898
We describe tunable vertical cavity surface emitting lasers with a half-sym
metric cavity structure. The cavity is realized by inducing a curvature (R
similar to 300 mu m) in the top movable dielectric mirror. This half-symmet
ric microcavity forces lasing oscillations in a single fundamental spatial
mode with a side-mode suppression ratio of > 25 dB. Continuous wavelength t
uning of 44 nm was achieved microelectromechanically with a tuning voltage
of 14 V. The device operates near 950 nm with maximum power output of simil
ar to 0.9 mW. (C) 1999 American Institute of Physics. [S0003-6951(99)04833-
