    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.

    摘要: A waveguide structure includes a SOI substrate. A core structure is formed on the SOI substrate comprising a plurality of multilayers having alternating or aperiodically distributed thin layers of either Si-rich oxide (SRO), Si-rich nitride (SRN) or Si-rich oxynitride (SRON). The multilayers are doped with a rare earth material so as to extend the emission range of the waveguide structure to the near infrared region. A low index cladding includes conductive oxides to act as electrodes.

    摘要: A method for enhancing photoluminescence includes providing a film disposed over a substrate, the film including at least one of a semiconductor and a dielectric material. Light emission may be activated by thermal annealing post growth treatments when thin film layers of SiO2 and SiNx or Si-rich oxide are used. A first annealing step is performed at a first temperature in a processing chamber or annealing furnace; and, thereafter, a second annealing step is performed at a second temperature in the processing chamber or annealing furnace. The second temperature is greater than the first temperature, and the photoluminescence of the film after the second annealing step is greater than the photoluminescence of the film without the first annealing step.

    摘要: An optical waveguide structure includes an air-via region that receives an optical signal from an optical source. A photonic crystal cladding region is formed on the surface of the air-via region. The photonic crystal cladding region confines the optical signal within the air-via region and propagates the optical signal along the axial direction while ensuring near complete transmission of the optical signal.
