A new concept of an all-optical wavelength-selective two-channel switch based on the photonic hook effect without the use of micromechanical devices or nonlinear materials is proposed. A prototype of such a device based on an off-axis Fresnel zone plate is considered and its main parameters are discussed. Due to the unique property of the photonic hook to change its curvature with respect to the irradiation wavelength λ, this switch is a promising candidate for the implementation of optical switching in modern optoelectronics and miniature ‘on-a-chip’ devices. Numerical simulation shows that the optical isolation of switched channels for a switch with linear dimensions of about (6λ)³ based on an off-axis zone plate can reach 18 – 20 dB during operation in the wavelength range of 1.5 – 1.9 μm.

提出了一种基于光子钩效应的全光波长选择性双通道开关的新概念，无需使用微机械器件或非线性材料。考虑了基于离轴菲涅耳波带板的这种设备的原型，并讨论了其主要参数。由于光子钩具有改变其相对于照射波长λ 的曲率的独特性质，因此该开关是在现代光电子学和微型“片上”设备中实现光开关的有希望的候选者。数值模拟表明，对于线性尺寸约为 (6 λ ) ³的开关，开关通道的光隔离 在 1.5 – 1.9 μm 的波长范围内工作期间，基于离轴波带板可以达到 18 – 20 dB。
