中文摘要:

我们理论上并且数字地证明慢光能在 photonic 水晶线缺点波导提高硅的参量的过程。明确地,能被减少为给定的泵力量得到需要的获得,为给定的获得媒介长度的泵力量或获得媒介长度由( c/v g n )2什么时候慢点亮波导,被使用,在 n 是常规波导的材料索引的地方, v g 是慢轻的波导的组速度, c 是在真空的轻速度。

英文摘要:

We demonstrate both theoretically and numerically that slow light can enhance the parametric process of silicon in photonic crystal line-defect waveguides. Specifically, to get the desired gain, the pump power for a given gain medium length or the gain medium length for given pump power can be reduced by (c/vgn)^2 when slow light waveguides are used, where n is the material index of conventional waveguide, vg is the group velocity of the slow light waveguide and c is the light velocity in vacuum.
