摘要

为了实现紧凑结构下光的主动调控, 设计了一种基于表面等离激元解复用器结构的双通道全光开关。该器件由金属-克尔非线性材料-金属的波导结构和谐振腔组成, 具有主动光控功能。通过对该开光结构进行优化, 实现了735 nm抽运光调控1310 nm信号光。该信号光在左右两个端口可实现输出与截止, 消光比可达到29.4 dB, 开关响应时间可达到50 fs。该双通道开关具有结构简单紧凑、易于集成、响应速度快等优点, 将在纳米集成光学中具有重要的应用价值。

Abstract

To realize the active light control with compact structure, we design an optical switch based on plasmonic demultiplexer. The device is composed of metal-Kerr nonlinear material-metal waveguide and resonant cavities, providing the function of active optical regulation. With the multiple parameter optimization, the signal with wavelength of 1310 nm can be controlled by pump light with wavelength of 735 nm. The signal can realize output and cut off at two output. The directional extinction ratio can reach to 29.4 dB and the response time is only 50 fs. The dual-channel all-optical switch has the advantages of simple and compact structure, easy integration, fast response, and so on, it will has importance application in naono-integrated optics.
