Description
Free-standing “AMTIR-1” (Ge33As12Se55) chalcogenide glass films have been patterned using a focused ion beam (FIB) to create twodimensional photonic crystal membranes. The triangular lattices were selected for a photonic bandgap relevant to fiber telecommunications. Optical measurements of transmission spectra as a function of incident angle showed clear signs of Fano resonances, indicating that the structures had strongly modified guided modes.
