Abstract
We present a simple and fast technique for the design of ring
resonator-based optical filters. The technique is based on tapering the ring
scattering parameters to achieve the optimal filter response. A perturbation
method is developed for the linearization of the resulting design problem.
The design problem is then formulated as an optimization problem. The
optimal filter design is achieved by solving a constrained linear least
square problem. This optimization problem can be solved efficiently to get
the global optimal design. Our technique has been verified using different
proposed targeted filter responses.
