Abstract: We present an efficient method for calculating the phase profiles of imaging and nonimaging optical systems composed of one or more cascaded metasurfaces, such as metalenses and concentrating metasurfaces. This method is a generalization of… read more here.

Abstract: We propose an optical tweezer with tunable potential wells, by dynamically manipulating the phase gradient of light. Using our proposed method to design holograms, we can obtain desirable phase profiles and intensity distributions of optical… read more here.
