    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 light emitting device is provided that includes at least one first semiconductor material layers and at least one second semiconductor material layers. At least one near-direct band gap material layers are positioned between the at least one first semiconductor layers and the at least one second semiconductor material layers. The at least one first semiconductor layers and the at least one second material layers have a larger band gap than the at least one near-direct band gap material layers. The at least one near-direct band gap material layers have an energy difference between the direct and indirect band gaps of less than 0.5 eV.

    摘要: The invention provides a waveguide with a waveguide core having longitudinal sidewall surfaces, a longitudinal top surface, and a longitudinal bottom surface that is disposed on a substrate. An interface layer is disposed on at least one longitudinal sidewall surface of the waveguide core. A waveguide cladding layer is disposed on at least the waveguide core sidewall and top surfaces, over the interface layer. The waveguide of the invention can be produced by forming a waveguide undercladding layer on a substrate, and then forming a waveguide core on the undercladding layer. An interface layer is then formed on at least a longitudinal sidewall surface of the waveguide core, and an upper cladding layer is formed on a longitudinal top surface and on longitudinal sidewall surfaces of the waveguide core, over the interface layer.
