Abstract

We present theoretical results of a low-loss all-optical switch based on electromagnetically induced transparency and the quantum Zeno effect in a microdisk resonator. We show that a control beam can modify the atomic absorption of the evanescent field which suppresses the cavity field buildup and alters the path of a weak signal beam. We predict more than 35 dB of switching contrast with less than 0.1 dB loss using just 2 μW of control-beam power for signal beams with less than single photon intensities inside the cavity.

All-optical-switching demonstration using two-photon absorption and the Zeno effect

Low-contrast all-optical Zeno switching has been demonstrated in a Si${}_{3}$N${}_{4}$ microdisk resonator coupled to warm atomic vapor. 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.

Microresonator-based all-optical transistor

B. D. Clader, S. M. Hendrickson

We present theoretical estimates for a low-loss, all-optical transistor using a microresonator device whose fields interact evanescently with rubidium vapor. We use a four-level, electromagnetically induced absorption scheme to couple the light fields of the transistor. We show results indicating that a weak control beam with less than single-photon intensities can switch a much stronger signal beam with switching contrast of greater than 25 dB and loss less than 0.5 dB.
