We introduce a new all-optical mechanism that can compress the bandwidth of light pulses to absolute zero, and bring them to a complete stop. The mechanism can be realized in a system consisting of a waveguide side coupled to tunable resonators, which generates a photonic band structure that represents a classical analogue of the electromagnetically induced transparency. The same system can also achieve a time-reversal operation. We demonstrate the operation of such a system by finite-difference time-domain simulations of an implementation in photonic crystals.
我们介绍了一种全新的全光机制，该机制能够将光脉冲带宽压缩至绝对零值，并使其完全停止。此机制可在一个由与可调谐谐振器侧面耦合的波导组成的系统中实现，该系统会产生一种光子能带结构，它代表了电磁诱导透明的经典类似物。同一系统还能实现时间反转操作。我们通过对光子晶体中一种实现方式的时域有限差分模拟，展示了这样一个系统的运行情况。
