Semiconductor Bragg mirrors with embedded quantum wells possess a hyperbolic dispersion of their eigen-modes that is typical for hyperbolic metamaterials. Their optical properties are tuneable by changing the transmittance of embedded quantum wells by application of external bias. This enables to control the group velocity and refraction angle of light.

Abstract
Semiconductor Bragg mirrors with embedded quantum wells possess a hyperbolic dispersion of their eigen-modes that is typical for hyperbolic metamaterials. Their optical properties are tuneable by changing the transmittance of embedded quantum wells by application of external bias. This enables to control the group velocity and refraction angle of light.File in questo prodotto:
