Abstract

The inhibition and enhancement phenomenon of spontaneous emission of PbSe QDs at the second-order stop-gap in a woodpile photonic crystal fabricated by the flexible direct femtosecond laser writing method is investigated. An inhibition of the emission is measured for wavelengths within the stop-gap with a maxima reached at the center of the stop-gap. At the high-energy band edge of the stop-gap, an enhancement of the spontaneous emission is observed.
