P03–Flat-Spectral-Band Filter for Fabrication Tolerance and Wideband Spectral Range

Novel scheme for silicon-wire type flat-topped wavelength filter is proposed and theoretically verified. Multimode interference couplers with symmetric and asymmetric splitting ratios used in a delayed interference type filter made filtering spectra flat over wide wavelength range of >80 nm with potentially better production yield
