摘要：A phasar (arrayed waveguide grating) including a gmented waveguide

The optimization may be performed by an evolutionary algorithm which generates random variations into the design population and lects the better members in a multi-generational lection process. The flattened passband phasar is particularly uful in a wavelength-division multiplexing (WDM) fiber communications network.
