The device is based on the suppression of the resonant microcavity field buildup due to nondegenerate two-photon absorption. This experiment used one beam in a resonator and one in free space due to limitations related to device physics. These results suggest that a similar scheme with both beams resonant in the cavity would correspond to input power levels below 150 nW.5 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
