Tuning a two-dimensional photonic crystal resonance via optical carrier injection

Opt Lett. 2005 Jan 1;30(1):64-6. doi: 10.1364/ol.30.000064.

Abstract

We report on wide wavelength tuning through optical injection of carriers of a photonic resonance observed in reflectivity at 1543 nm in an InP-based two-dimensional photonic crystal slab. An 8-nm blueshift, which represents 20 times the resonance linewidth, is observed when a 4-kW/cm2 intense optical pump is incident on the sample. An analytical model that we developed, based on a coupled-mode nonlinear approach, allows us to describe this phenomenon in detail.
