摘要：
Cyclic arrayed waveguide grating (AWG) devices with flat-top passband and uniform spectral response are proposed. Each access waveguide of the proposed cyclic AWG consists of a multimode interference region and a taper waveguide. Simulation results show that the 1-dB bandwidth of the proposed device is larger than 0.44 times the channel spacing and the corresponding nonuniformity is smaller than 1 dB.
