Optical modulator devices exhibiting improved response characteristics are constructed from a ring resonator having a tunable loss element positioned within the ring resonator structure and one or more phase shifters. By tuning and/or controlling the loss within the resonator, desired modulator response characteristics are obtained.
1. An optical apparatus comprising:
an optical modulator having an input waveguide connected to an output waveguide by two waveguide arms, said modulator for modulating an input optical signal; and
an optical resonator optically coupled to at least one of the two waveguide arms of the optical modulator;
CHARACTERIZED IN THAT:
said optical resonator is included in the at least one of the two waveguide arms, and positioned such that it is within the physical waveguide arm and within the light path defined by said arm wherein all light traversing in the arm necessarily traverses the resonator, wherein a plurality of tunable elements positioned within the resonator adjust in a frequency space, a resonance location of the resonator,
such that upon modulating the input optical signal present at the input waveguide, the modulator adjusts the modulation response characteristics of a modulated output optical signal at the output waveguide.
