Optoelectronic Arrangement Provided with a Semiconductor Nanowire with a Longitudinal Section that is Surrounded by a Part of a Mirror

摘要

The optoelectronic arrangement comprises a semiconductor nanowire intended to participate in the processing, notably in a reception and/or an emission, of a light concerned and a mirror reflecting the light concerned. The semiconductor nanowire comprises a first section and a second section, and the mirror surrounds, at least longitudinally, the first section of the semiconductor nanowire, said second section extending out of the mirror.

1. An optoelectronic arrangement comprising:
a semiconductor nanowire to participate in the processing of a light, the semiconductor nanowire comprising a first section and a second section: and a mirror to reflect the light, said mirror surrounding at least longitudinally, the first section of the semiconductor nanowire, said second section extending out of the mirror, wherein: an aperture of the mirror wholly or partly filled by the first section has lateral aperture dimensions less than λ/5n, with n being the refractive index of the material of the first section of the semiconductor nanowire, and λ being the wavelength of the light, the mirror rests on a substrate and comprises a layer that is reflective to the light and a buffer layer that is transparent to the light increasing the reflectivity of the mirror, the reflecting layer being arranged between the substrate and the buffer layer.
