A micromechanically controlled Gires-Tournois interferometer (micro-GTI) is
proposed for a tunable dispersive medium for use in optical-pulse compress
ion. Its dispersive properties, which are controlled by comb-drive micromir
ror actuation, were theoretically and experimentally evaluated to verify it
s capability to generate ultra-short optical pulses. Pulse compression perf
ormed using this micro-GTI generated nearly transform-limited pulses with a
duration of 0.43 ps. (C) 2000 Elsevier Science S.A. All rights reserved.
