    摘要: An optical switch operating with an optical pumping source. The switch includes a microcavity structure that is resonant with both the pumping source and the input optical signal. The microcavity structure includes a cavity in between two reflectors. The input optical signal is switched from one to zero, by varying the pump source intensity. The microcavity provides amplification of the pumping energy allowing for a nonlocal optical power source. In addition it also provides a way for fast optical modulation of the input optical signal using continuous wave pumping source.

    摘要: A condensed matter structure includes a substrate having a resonant microcavity formed by reflectors, having a reflectivity R, arranged relative to an optically-active material to form a cavity. The optically-active material has a thickness L, an optical emission line centered at a wavelength &lgr;c, and an optical absorption coefficient &agr;0 at &lgr;c. The magnitude of absorption (&agr;0L) at &lgr;c by the optically-active material is greater than the probability (1−R) that an electromagnetic field having an energy of &lgr;c exits microcavity and thereby results in a strong light-matter interaction between the optically-active material and the electromagnetic field confined in the microcavity.

    摘要: A wavelength converter includes an optical resonator that is optically coupled to a waveguide. The refractive index of the optical resonator is dynamically changed, such as by injecting free carriers into the resonator. This effectively changes that optical path length of the light, thus converting the wavelength.
