Abstract
An optical resonator having a non-continuous waveguide having first and second confrontingly opposite end faces between which is defined a region and having a continuous optical path defined through the waveguide. The optical resonator can be tuned to a particular resonant wavelength by providing a phase shifter in the region between the first and second end faces and positioning the phase shifter so as to introduce a phase shift in an optical signal propagating through the waveguide and along the optical path. A method for effecting such a phase shift.
