Quantized state in a single quantum well structure of photonic crystals - art. no. 153316

A quantum well structure was fabricated using two kinds of photonic crystal . The transmittance spectra were measured in the millimeter wavelength rang e for various well thicknesses, and numerous sharp peaks due to quantized s tates were observed in the high reflective frequency region of the barrier crystal. To discuss the symmetry of observed quantized states, the electric al field patterns in the well crystal were measured. Even and odd modes wer e observed alternately in each fine peak. The results of analysis showed th at the observed fine peaks were quantized states of a photonic band in a si ngle quantum well.
