An optical resonator with intracavity Kerr nonlinearity can exhibit dispersive bistability suitable for alloptical switching. With nanophotonic elements it may be possible to achieve attojoule switching energies, which would be very attractive for ultra-low power operation but potentially problematic because of quantum fluctuation-induced spontaneous… CONTINUE READING
