Dressing field control of band gap reflection is investigated in an inverse Y-type four-level atomic system. It is shown that when the dressing field is blocked, a band gap reflection with a maximum bandwidth and nearly ~90% reflectivity can be achieved for the detuning of the coupling field . When a weak dressing field is applied to the system (the intensity is much less than that of the coupling field), a narrowing top flat with ~86% reflectivity of the band gap reflection is observed in comparison with that in the first case. We also show that the band gap reflection can be dramatically suppressed due to the collapse of the stop band when a strong dressing field (the intensity is comparable with or larger than that of the coupling field) is employed. This control of photonic band gap reflection can be used in the applications of all-optical reflection mirrors and band optical filters.

Different experimental strategies towards the 3-dimensional photonic crystals operating at optical wavelength are classified. The detailed discussion is devoted to the recent progress in photonic crystals fabricated by template method — the photonic band gap materials on the base of opal. The control of photonic properties of opal-based gratings is achieved through impregnating the opal with high refractive index semiconductors and dielectrics. Experimental study demonstrated the dependence of the stop band behaviour upon the type of impregnation (complete or partial) and showed a way for approaching complete photonic band gap. The photoluminescence from opal- semiconductor gratings revealed suppression of spontaneous emission in the gap region with following enhancement of the emission efficiency at the low-energy edge of the gap.
