| Abstract: | In an N-type atomic system with double electromagnetically induced transparency, when the traveling-wave coupling field is replaced by a standing-wave, double fully developed photonic band gaps open up due to space-modulated refractive index within the two electromagnetically induced transparency widows. The dynamically induced band gaps can be tuned coherently, and have applications in manipulating the propagation dynamics of light pulses. |
