具有零吸收的光学可控光子结构

Optically controllable photonic structures with zero absorption

Chris O'Brien, Olga Kocharovskaya

摘要:

我们展示了在空间或/和时间上对原子介质中的折射率进行周期性调制,同时保持吸收/增益消失的可能性。这种调制基于折射率的周期性共振增强,由外部光场控制,并开辟了一种方法来产生相干可控的光子结构。我们提出了在具有激发态吸收的稀土掺杂晶体中可能实施所提出的方案。

英文摘要:

We show the possibility to periodically modulate refractive index in atomic medium in space or/and time while simultaneously keeping vanishing absorption/gain. Such modulation is based on periodic resonant enhancement of refractive index, controlled by an external optical field, and opens a way to produce coherently controllable photonic structures. We suggest possible implementation of the proposed scheme in rare-earth doped crystals with excited state absorption.
