Abstract
An injection-seeded whispering gallery mode optical amplifier. The amplifier includes a micro or nanoscale whispering gallery mode resonator configured to amplify a whispering gallery mode therein via a gain medium separated from the whispering gallery mode resonator but within the evanescent field of the whispering gallery mode resonator. A pump stimulates the whispering gallery mode. A plasmonic surface couples power into the whispering gallery mode resonator.
