    摘要: An optical system includes a delay region having a photonic band structure, a modulated optical signal source, an optical input, and an optical output. The optical input couples modulated input optical signals into a predetermined mode in the delay region such that group velocity of the optical signal is reduced. The optical output includes a wavelength selective element. Input optical signals are coupled into a highly dispersive mode in the delay region in which the group velocity of the optical signal is reduced. The input signal, which has been delayed and dispersed, is recovered at the output of the device using the wavelength selective element.

    摘要: A light emitting device having a plurality of light extracting elements defined on an upper surface of a semiconductor layer of the device, wherein the light extracting elements are adapted to couple light out of the device and to modify the far field emission profile of the device. Each element comprises an elongate region having a length at least twice its width and also greater than the effective dominant wavelength of light generated in the device. The elongate region extends orthogonal to the upper surface but not into the light emitting region of the device and may be oriented at an angle of less than 45° relative to one of a pair of basis axis defining a plane parallel to the semiconductor layer. Each elongate region is spatially separated from neighboring elongate regions such that it perturbs light generated in the light emitting region independently of the neighboring regions.

    摘要: A planar optical platform for generating a Raman signal from a foreign object comprises an input region and an output region, for receiving and extracting optical radiation, optically coupled to a plasmonic band structure region. The plasmonic band structure region comprises a layer of a first material, having a first refractive index, patterned with an array of sub-regions of a second material, having a second refractive index, wherein a side-wall of each sub-region is coated with a metallodielectric layer. The array of sub-regions gives rise to a plasmonic band structure and, in use, each sub-region confines a plasmon resonance excited by optical radiation coupled into the plasmonic band structure region, which gives rise to a Raman signal from a foreign object placed proximate the plasmonic band structure region. The platform may be incorporated into a spectroscopic measurement system and is particularly useful for surface-enhanced Raman spectroscopy of analyte molecules.

    摘要: Light emitting diode (LED) structures are described that include a first layer and a light-generating layer, wherein light generated in the light-generating layer generally emerges from the LED structure through the upper surface of the first layer. The coupling out of light generated by spontaneous emission is enhanced by the presence of patterning in the first layer, which may take the form of an embedded photonic quasicrystal, a photonic structure comprising an amorphous array of subregions, or a zone plate structure. The invention provides the benefit of improved light extraction from the LED without undesirable far field illumination patterns.

    摘要: A light-emitting device (LED) is described which exhibits high extraction efficiency and an emission profile which is substantially more directional than from a Lambertian source. The device comprises a light generating layer disposed between first and second layers of semiconductor material, each having a different type of doping. An upper surface of the first layer has a tiling arrangement of pyramidal or frustro-pyramidal protrusions of semiconductor material surrounded by a material of different refractive index which together comprise a photonic band structure. The protrusions and their tiling arrangement are configured for efficient extraction of light from the device via the upper surface of the first layer and in a beam that is substantially more directional than from a Lambertian source An enhanced device employs a reflector beneath the second layer to utilize the microcavity effect. A method for fabricating the device is also described which employs anisotropic wet etching to produce the pyramidal or frustro-pyramidal protrusions
