Electromagnetically induced transparency and nonlinear pulse propagation in an atomic medium confined in a waveguide
Laing Li, Chengjie Zhu, Lu Deng, Guoxiang Huang
We study electromagnetically induced transparency (EIT) and nonlinear pulse propagation in a resonant atomic gas confined in a micro-waveguide. We find that quantum interference effect in this system can be largely enhanced due to the reduction of the mode volume of optical field. In particular, comparing with atomic gases in free space, the EIT transparency window in the present confined system can be much wider and deeper, the group velocity of probe field can be much slower, and the Kerr nonlinearity of the system can be much stronger. We show that a more efficient production of ultraslow optical solitons in the present system may be achieved with much slower propagating velocity and lower generation power. Novel features of EIT and pulse propagation in the present system are very promising for practical applications in optical information processing and transmission.
