Visible Wavelength Negative Index Materials

Leveraging Agiltron's recent breakthrough in photonic nano-manufacturing technology and research on photonic crystals together with Northeastern University's know-how in the research of negative index material, we propose to design and fabricate a negative index photonic crystal material and establish its potential for negative refraction and subwavelength imaging at visible wavelengths. Our preliminary analysis has confirmed our design concept. Our approach will provide a convenient manufacture route for making negative index materials working at visible or NIR wavelength range. The tolerance, such as the size of lattice, the roughness of the surface and walls, will be calculated in the simulation. In Phase I, a practical design of a flat lens, operating at visible or IR wavelength, will be completed. A one layer (2D) PC will be fabricated and tested. Simulation on multi-layer (3D) PC will also be carried out.
