Properties of Broadband Soliton Microcombs in Pulse-Driven Integrated Microresonators
(2019)Recently, pulse-driving of nonlinear microresonators, as opposed to continuous-wave driving (CW), has been demonstrated as a powerful method for overcoming the fundamental inefficiency of single-state dissipative Kerr ... -
Shaping field correlation with entangled quantum antennas
(2017-11-13)A quantum antenna can shape spatial entanglement of emitted photons originating from entangled states of antennas emitters. In contrast to the classical antenna, the quantum antenna can shape the second and higher order ...
