Abstract

The method of passive thermal compensation of the arrayed waveguide grating (AWG) demultiplexer based on a cut in the input planar waveguide and a controlled angle of rotation of a part of this waveguide is investigated. A possibility of performing this thermal compensation is shown, restrictions on the choice of the demultiplexer parameters to be observed for functioning of the demultiplexer are obtained, and relevant recommendations are given. A simple algebraic expression for the derivative of the compensation angle with respect to temperature is obtained, which is needed for development of the demultiplexer. In the given numerical example, this derivative is 3.5 × 10^–5 rad/K.

集成光学多路分解器光谱特性的无源热补偿

研究了阵列波导光栅（AWG）解复用器的无源热补偿方法，该方法基于输入平面波导中的切口和该波导部分的受控旋转角。显示了执行这种热补偿的可能性，获得了对多路分解器的功能所要观察的多路分解器参数的选择的限制，并给出了相关的建议。获得了补偿角相对于温度的导数的简单代数表达式，这是多路分解器的开发所需要的。在给定的数值示例中，该导数为3.5×10–5 rad/K。
