Theory and simulation of subwavelength high contrast gratings and their applications in vertical-cavity surface-emitting laser devices
… the qualities and applications of subwavelength gratings. Subwavelength gratings are diffraction gratings with physical dimensions less than the wavelength of incident light. It has been found that by tailoring specific dimension parameters, a number of different reflection profiles can be …
