HIGH FREQUENCY RESONATOR MODULATOR APPARATUS, METHOD AND APPLICATIONS

摘要

A ring resonator modulator and a modulation method that uses the ring resonator modulator each are predicated upon a modulation frequency of a ring shaped waveguide comparable to a free spectral range of the ring shaped waveguide. Fulfillment of this condition provides for a comparatively higher frequency optical modulation at a comparatively lower power consumption. A particular ring resonator modulator structure employs as an actuator a p-n diode that includes from about 25 to about 50 percent of the ring shaped waveguide and having a depletion region that is contained within the ring shaped waveguide.
