Researchers from the Purdue University have hopped a stride forward in the invisibility cloak endeavor by developing more feasible applications in transformation optics, this one based on a much simpler tapered optical waveguide. A more practical development to work for all colors of the visible spectrum, this conception courtesy the tapered optical waveguide can cloak almost 100 times the area of the wavelengths of light that are created by shining a laser into the device, thereby increasing the cloak area comprehensively than ever made possible. Purdue, with BAE Systems, has tested the technology by succeeding in cloaking an object about 50 microns in diameter (close to the width of human hair) in the center of the waveguide. Thus it’s believed that the technology could open different parameters for itself resulting in 10 times more powerful microscopes, computers and electronics that use light instead of electronic signals and advanced sensors, but it’s a long way off still.
