A new type of band-stop filter with center frequency at 1.55 μm and band width about 10 nm is designed,which is based on the high-order forbidden band of one-dimensional photonic crystal(1D PC) with a structure of Si(air|Si)5.The periodic length of 1D PC is 15 μm and it is fabricated on SOI materials by lithographic process and inductively coupled plasma(ICP) process.The filter transmittance spectra are measured and analyzed,and the results obtained from experiment can agree well with that of theory.The results prove that the high-order band gap is an effective method to lower the fabrication difficulty of PC.
