Continuous Phase Modulation (CPM) constitutes a family of constant-envelope digital modulation techniques in which symbol transitions occur with continuous phase trajectories. By maintaining a ...

Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...

Computational optics introduces computation into optics and consequently helps overcome traditional optical limitations such as low sensing dimension, low light throughput, low resolution, and so on.
