Engineering broadband and anisotropic photoluminescence emission from rare earth doped tellurite thin film photonic crystals

Opt Express. 2012 Jan 30;20(3):2124-35. doi: 10.1364/OE.20.002124.

Abstract

Broadband and anisotropic light emission from rare-earth doped tellurite thin films is demonstrated using Er3+-TeO2 photonic crystals (PhCs). By adjusting the PhC parameters, photoluminescent light can be efficiently coupled into vertical surface emission or lateral waveguide propagation modes. Because of the flexibility of light projection direction, Er3+-TeO2 is a potential broadband light source for integration with three-dimensional photonic circuits and on-chip biochemical sensors.
