Photonic Crystal Based Subwavelength Imaging and Cloaking Optical Devices

摘要：

Potentialities of 2.5D dielectric photonic crystals for subwavelength imaging or invisibility cloaking operation at optical wavelengths are studied numerically and experimentally. First, a negative refraction based flat lens is designed, fabricated and characterized. Using scanning near-field optical microscopy, subwavelength imaging (0.8? for a deduced refractive index of -1 is obtained at 1.55 μm. Second, an original design aimed to operate as a cloaking device is proposed by combining photonic lattices operating under different regimes, exploiting both passand stop-band properties.
