摘要

Development of optical systems is toward smaller sizes,more new functions and improved device performance.However,traditional optical systems face many fundamental limits.For example,the Abbe's diffraction limit sets a minimal value at which the optical microscopy,telescopy and lithography resolution can be achieved.On the other hand,the Snell's law states that one can only change the shape or materials of optical elements to realize different optical functionalities.
