Compact Structural Design of Arrayed Waveguide Grating
AWG结构的优化设计

It is very important that the larger number of chan nels of AWG can be obtained on a definite wafer. The compact design of AWG presented in this paper was based on two restricting equations and optimizing the distant between the two focuses of AWG through analyzing the inclination of central waveguide. A design method was proposed, by which the rest structure parameters can be exactly determined with the minimum bending radius of waveguides, pitch of adjacent input/output waveguides, and a desired compact AWG can be obtained. An example was presented at last.
