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.
