Suppressing Spontaneous Emission Inside a Photonic Crystal
Scientists at the University of Twente (Netherlands) have demonstrated a prediction made nearly a quarter-century ago: that spontaneous emission of light can be inhibited within a 3-D photonic bandgap.

Scientists at the University of Twente (Netherlands) have demonstrated a prediction made nearly a quarter-century ago: that spontaneous emission of light can be inhibited within a 3-D photonic bandgap (Phys. Rev. Lett. 107, 193903). By learning how to control such emission and suppression, researchers could someday build better solid-state lasers or reduce the noise in quantum computers.
