本发明专利技术公开了一种波长选择的方法和波长选择开关WSS，涉及光通信技术领域。一种波长选择开关WSS，包括输入光路单元、光斑偏转单元和输出光路单元三个部分。其中，所述光斑偏转单元用于对由所述输入光路部分输出的多个单波长光信号进行空间角度的偏转并发送到所述输出光路单元，用于控制所述多单波长光信号的输出端口位置。该光斑偏转单元包括偏转器件和控制电路，所述偏转器件由至少两个偏转面组成，所述控制电路用于控制入射到所述至少两个偏转面的光信号的空间偏转角度。通过光斑偏转单元来改变光斑的空间位置，从而使得光信号可以从更多的输出光纤端口输出，提升了WSS的端口数目。此外，光斑偏转单元通过改变光斑位置以增大光斑间的间距，从而使得WSS具备改善通道串扰的能力。

Wavelength selection method and wavelength selection switch

The invention discloses a wavelength selection method and a wavelength selection switch WSS, which relates to the technical field of optical communication. A wavelength selective switch WSS includes three parts: input optical path unit, spot deflection unit and output optical path unit. Wherein, the facula deflection unit is used to deflect the spatial angle of a plurality of single wavelength optical signals outputted by the input optical path part and send it to the output optical path unit for controlling the output port position of the plurality of single wavelength optical signals. The spot deflection unit includes a deflection device and a control circuit, the deflection device is composed of at least two deflection surfaces, and the control circuit is used to control the spatial deflection angle of the light signal incident on the at least two deflection surfaces. The spatial position of the facula is changed by the facula deflection unit, so that the optical signal can be output from more output fiber ports, and the number of ports of WSS is increased. In addition, the deflection unit can increase the distance between the facula by changing the position of the facula, so that WSS has the ability to improve channel crosstalk.
