Bridging Microscopic Nonlinear Polarizations toward Far-Field Second Harmonic Radiation
Kyungwan Yoo, Simon F. Becker, Martin Silies +3
Since the first observation of second harmonic generation (SHG), there have been extensive studies on this nonlinear phenomenon not only to clarify its physical origin but also to…
Transverse spinning of light with globally unique handedness
Xianji Piao, Sunkyu Yu, Namkyoo Park
Access to the transverse spin of light has unlocked new regimes in topological photonics and optomechanics. To achieve the transverse spin of nonzero longitudinal fields, various p…
Dynamical phase diagram of parity-time symmetry with competing saturable channels
Sunkyu Yu, Xianji Piao, Namkyoo Park
Nonlinear channels play a critical role in realizing dynamical functions. Neural ionic channels and non-volatile memristors each derive representative biological and electrical fun…
Interface defect-assisted phonon scattering of hot carriers in graphene
Sergey Menabde, Hyunwoo Cho, Namkyoo Park
The broadband and ultrafast photoresponse of graphene has been extensively studied in recent years, although the photoexcited carrier dynamics is still far from being completely un…
