Abstract:
This invention provides devices and methods for broad-band amplification of non linear properties. This invention provides devices comprising optically non linear material that is in contact with a slit array. The slit array causes enhancement of the electromagnetic field within the non linear materials. The enhancement of the electromagnetic field within the optically non linear material results in an amplified non linear response exhibited by the optically non linear materials. This invention provides detectors and imaging systems based on devices and methods of this invention.
