ABSTRACT:
The present invention provides photonic crystal devices, device components and methods for preventing transmission of electromagnetic radiation from one or more laser sources or laser modes so as to provide an optical shield for protecting a users eyes or an optical sensor. The present invention also provides dynamic photonic crystals and devices incorporating dynamic photonic crystals for optically modulating the intensity of one or more beams of electromagnetic radiation and other optical switching applications.
