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.
