An Optical Device

An improved optoelectronic device is described, which employs optically responsive nanoparticles and utilises a non-radiative energy transfer mechanism. The nanoparticles are disposed on the sidewalls of one or more cavities, which extend from the surface of the device through the electronic structure and penetrate the energy transfer region. The nanoparticles are located in close spatial proximity to an energy transfer region, whereby energy is transferred non-radiatively to or from the electronic structure through non-contact dipole-dipole interaction. According to the mode of operation, the device can absorb light energy received from the device surface via the cavity and then transfer this non-radiatively or can transfer energy non-radiatively and then emit light energy towards the surface of the device via the cavity.; As such, the deice finds application in light emitting devices, photovoltaic (solar) cells, displays, photodetectors, lasers and single photon devices.
