Abstract
To relax the requirements on wavelength control of arrayed waveguide grating (AWG) in InP-based photonic integrated circuits (PIC), two kinds of 10-channel InP-based AWGs with flat-top spectral response are designed and fabricated by introducing a rectangle multi-mode interference (MMI) or a parabolic MMI at the end of input waveguide. The test results demonstrate that these two kinds of flat-top AWGs have obtained flattened spectral response with 3Â dB-bandwidth of about 1.7Â nm, and the parabolic MMI-based flat-top AWG has 0.7Â dB superiority in on-chip loss.
