摘要： A light emitting diode (100 or 150) includes a diode structure containing a quantum well (120), an enhancement layer (142), and a barrier layer (144 or 148) between the enhancement layer (142) and the quantum well (120). The enhancement layer (142) supports plasmon oscillations at a frequency that couples to photons produced by combination of electrons and holes in the quantum well (120). The barrier layer serves to block diffusion between the enhancement layer (142) and the diode structure.

摘要： A lens is described which includes a substrate having a first side and an opposite second side. A first guided mode resonance grating is supported by the first side of the substrate and a second guided mode resonance grating is supported by the second side of the substrate. The second guided mode resonance grating can be offset from the first guided mode resonance grating. The second guided mode resonance grating can shape and reflect a wave front of an incident optical beam within the substrate towards the first guided mode resonance grating. The first guided mode resonance grating can redirect the reflected incident optical beam out of the second side of the substrate.

The given layer of given material can comprise an aligning seat to receive an optical transmitter to provide the optical signal. The aligning seat can also align the optical transmitter such that the optical transmitter provides the optical signal in a direction that is substantially non-oblique relative to a longitudinal axis of the optical waveguide. The optical engine can also include an optical signal redirector to tilt the optical signal by a tilt angle. The optical waveguide can comprise a grating coupler to diffract the optical signal provided at the tilt angle into the optical waveguide.
