A signal beam transmitted by a Fabry-Perot cavity is modulated by a control beam which changes the refractive index of the intracavity medium. High finesse at the signal wavelength and strong absorption at the control wavelengths result in efficient optical gating and modulation. Such modulation has been observed using GaAs (and using color filters) with switch-on times of 1 ns (10 μs) and switch-off times of 2–20 ns (1 ms), and a physical length of only 5 μm (60 μm).
