摘要：

Halting and storing light by infinitely decelerating its speed, in the absence of any form of external control, is extremely difficult to imagine. Here we present a theoretical prediction of a controllable optical black hole composed of a planar left-handed material slab. We reveal a criterion that the effective round-trip propagation length in one zigzag path is zero, which brings light to a complete stand still. Both theory and ab initio simulation demonstrate that this optical black hole has flexible controllability for the speed of light. Surprisingly, the ab initio simulations reveal that our scheme has flexible controllability for swallowing, holding, and releasing light. (C) 2010 Optical Society of America
