D. Labilloy et al., USE OF GUIDED SPONTANEOUS EMISSION OF A SEMICONDUCTOR TO PROBE THE OPTICAL-PROPERTIES OF 2-DIMENSIONAL PHOTONIC CRYSTALS, Applied physics letters, 71(6), 1997, pp. 738-740
We describe an experimental setup, which allows assessing the optical
properties of two-dimensional photonic crystals combined with a wavegu
ide geometry, and etched into a light-emitting (GaAs/InGaAs) semicondu
ctor. By means of a guiding layer, the spontaneous emission of the mat
erial is used as a built-in source to probe the properties of the etch
ed microstructure, conveniently compared to the usual measurement sche
mes. We show polarized transmission and coefficients largely depending
on the photonic crystal orientation. (C) 1997 American Institute of P
