Two_dimensional macroporous photonic crystal with mid_infrared band gap was fabr icated by electrochemical etching method in this work. The sample structure is o f square lattice with structure parameters: lattice constant a=4μm and the length of the square lattice structure l=2μm. The reflection spectrum of th e sample was measured using the microscopic infrared spectrometer and showed the photonie crystal characteristics.
