    摘要: An optical field concentrator includes a plurality of waveguide layers comprising high index materials having a first defined thickness. At least one nano-layer structure is positioned between said waveguide layers. The at least one nano-layer structure comprises low index materials having a second defined thickness that is smaller than the first defined thickness. A plurality of cladding layers are positioned between the waveguide layers and the at least one nano-layer structure. The cladding layers have a third defined thickness that is larger than the first defined thickness.

    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.

    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 fabrication method produces Si compatible light-emitting materials showing sizeable optical gain by thermally annealing thin film layers of Si-rich nitride (SiNx) By utilizing the Si compatible light-emitting material, light emitting devices can be fabricated that are compatible with CMOS processes. The Si compatible light-emitting material is a high index (refractive index ranging from 1.6 to 2.3) material allowing flexible design of high confinements photonic devices with strong structural stability with respect to annealing treatments. The Si compatible light-emitting material realizes broad band light emission by allowing resonant coupling with rare earth atoms and other infrared emitting quantum dots and better electrical conduction properties with respect to SiO2 systems. The Si compatible light-emitting material also realizes high transparency (low pumping and modal losses) in the visible range.

    摘要: A thin film quaternary compound semiconductor comprising arsenic (As), selenium (Se), tellurium (Te) and copper (Cu) atoms with adjustable molar concentrations during processing, whose atomic arrangement is predominantly amorphous, glassy or polycrystalline, and dominated by covalent chemical bonds between the said atoms. The amorphous nature of the atomic arrangement gives predominance to short range atomic order, eliminating the constraints of lattice constant mismatch and polarity mismatch with the substrate, which opens the way to wide chemical compositional adjustments and to lower-cost deposition processes such as thermal evaporation or sputtering.
