| Abstract: | An optical device includes a microdisk optical resonator element. The
microdisk resonator element is formed on a substrate and has upper and
lower portions respectively distal and proximal the substrate. An arcuate
semiconductor contact region partially surrounds the microdisk resonator
element. A first modulator electrode is centrally formed on the upper
portion of the microdisk resonator element, and a second modulator
electrode is formed on the arcuate contact region. A laminar
semiconductor region smaller in thickness than the microdisk resonator
element separates the arcuate contact region from the microdisk resonator
element and is formed on the substrate so as to electrically connect the
arcuate contact region to the lower portion of the microdisk resonator
element. |
