基于Kerr效应的微环谐振腔色散补偿器件

Study on Kerr effect-based micro-ring resonator dispersion-compensation devices

利用微环谐振腔中的光场关系实现了光学延时与色散补偿,并利用了Kerr效应来控制微环内相移的改变。文章给出了所设计器件的经过优化后的参数,可以在抖动<±8ps的条件下,达到>-1 200ps/nm的色散补偿数值,同时每个信道的色散补偿带宽均>20GHz,满足DWDM(密集波分复用)系统的要求。整个结构的功耗较小,不超过1.2mW,响应速度快,完全光控,体积小便于集成。

This paper realizes optical delay and dispersion compensation by using the optical field relationship in micro-ring re-sonators and controls the phase shift changes in the micro-ring by using the Kerr effect.Furthermore,it gives the optimized parameters of the designed device,which can reach a dispersion compensation value of greater than -1 200 ps/nm when the jittering is smaller than ＆#177;8 ps and at the same time,the compensation bandwidth of all channels are higher than 20 GHz,sat-isfying the requirements of DWDM systems.The entire structure is small in power consumption （less than 1 .2 mW）,fast in response,fully light controllable and small in volume and easy for integration.
