Adam Markman, Bahram JavidiWe investigate a full-phase-based photon-counting double-random-phase encryption (PC-DRPE) method. A PC technique is applied during the encryption process, creating sparse images. The statistical distribution of the PC decrypted data for full-phase encoding and amplitude-phase encoding are derived, ... [J. Opt. Soc. Am. A 31, 394-403 (2014)]

Jing Qi, Thomas Kaiser, Ralf Peuker, Thomas Pertsch, Falk Lederer, Carsten RockstuhlPlasmonic nanoantennas permit many functional components for future generations of nanoscale optical devices. They have been intensively studied and means were devised to engineer their optical response. However, as a metal-based resonator, the low quality factor of a plasmonic antenna hinders its ... [J.
