摘要： An optical device is provided including an optically localising region comprising a first region having a first refractive index and an array of sub-regions having a second refractive index, the sub-regions in the array positioned at each of the vertices of the triangles in a pinwheel tiling structure. Light passing through the optical device is localised by multiple scattering events within the localising region. The localising region is isotropic so that transmission in the same in all directions and strong localisation occurs for a relatively broad band of frequencies. This is beneficial in a number of applications. The structure can be easily replicated and that there is always a set minimum spacing between the sub-regions.

摘要： The invention provides a photonic structure comprising a first region (3) formed from a material having a first refractive index; and an array of sub-regions (5) formed in the first region, each sub-region having a refractive index different to the first refractive index; wherein the array of sub-regions (5) can be defined by a plurality of rows and columns, wherein the position of each sub-region relative to adjacent sub-regions in each row and the properties of the sub-regions across each row are defined by parameters of a first type, and the position of each row relative to adjacent rows, and the properties of the sub-regions along each column are defined by parameters of a second type; and wherein at least one parameter of a first type and at least one parameter of the second type is varied systematically and independently across the array. The present invention gives rise to structures with photonic band structures that can be tailored to a particular application. A variation in the first type of parameter has a different effect to a variation in the second type of parameter. Variation in a first type of parameter alters the diffracting properties of each row in the stack of rows. Variation in a second type of parameter affects the reflective properties of the structure. According to another aspect of the invention, a method for manufacturing photonic structures is provided including a computer optimisation process in the design stage.

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.

An upper surface of the first layer has a tiling arrangement of inverted pyramidal or inverted frustro-pyramidal indentations in the semiconductor material filled by a material of different refractive index and which together comprise a photonic band structure. The indentations 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.
