Optics Express, 2015 An integrated silicon nanophotonic coherent imager (NCI), with a 4 × 4 array of coherent pixels is reported. In the proposed NCI, on-chip optical processing determines the intensity and depth of each point on the imaged object based on the instantaneous phase and amplitude of the optical wave incident on each pixel. The NCI operates based on a modified

Materials Today, 2004 Paras N. Prasad's new book expands on his short course for photonics-oriented conferences to give a broad and comprehensive overview of nanophotonics in an informal and accessible style. It could also be used as a text for an introductory graduate-student-level seminar, says Naomi J. Halas .
