A solar cell that has a thin film of active material in which is defined a series or array of diffraction cells, wherein each diffraction unit-cell has a non-periodic series of diffraction features and is adapted to suppress at least one low order diffraction mode.

Thin film solar cell

An optical device including: a waveguide of refractive index nfor carrying at least one mode of at least one wavelength, and at least one resonator with a resonant wavelength. The resonator has a mode volume of less than ten cubic resonant wavelengths. In use light in the waveguide is vertically coupled into the at least one resonator, and the waveguide and resonator(s) are arranged to provide wave-vector matching between at least one mode of the resonator and at least one mode of the waveguide.

Wave vector matched resonator and bus waveguide system

An optoelectronic semiconductor component includes a semiconductor layer sequence having at least one active layer, and a photonic crystal that couples radiation having a peak wavelength out of or into the semiconductor layer sequence, wherein the photonic crystal is at a distance from the active layer and formed by superimposition of at least two lattices having mutually different reciprocal lattice constants normalized to the peak wavelength.

Optoelectronic semiconductor component and photonic crystal

An on-chip micro-fluidic device () fabricated using a semiconductor material. The device has a micro-fluidic channel or chamber () defined within the material and one or more monolithically integrated semiconductor lasers () operate to form an optical trap in the channel or chamber ().
