Abstract:
A tunable optical resonator comprising:an optical cavity having a first mirror and a second mirror, said first mirror and said second mirror separated by a distance, said first mirror and said second mirror being mounted with respect to one another such that a force applied to said second mirror will cause said distance between said mirrors to change, said resonator having a resonance characterized by a resonance response curve centered at a wavelength &lgr;0; a light source for generating a tuning light signal having a wavelength within said response curve; and a light input port for receiving said tuning light signal, said tuning light signal being introduced into said optical cavity such that said tuning light signal is reflected between said first and second mirrors, said tuning light signal having sufficient power to shift said wavelength of said resonance response curve to &lgr;1, wherein &lgr;1>&lgr;0.
