Two-Photon Polarization Interference for Pulsed SPDC in a PPKTP Waveguide
Malte Avenhaus, Maria V. Chekhova, Leonid A. Krivitsky +2
We study the spectral properties of Spontaneous Parametric Down Conversion in a periodically poled waveguided structure of KTP crystal pumped by ultra-short pulses. Our theoretical…
Pseudo spin-orbit coupling of Dirac particles in graphene spintronics
S. G. Tan, M. B. A. Jalil, Dax Enshan Koh +2
We study the pseudo spin-orbital (SO) effects experienced by massive Dirac particles in graphene, which can potentially be of a larger magnitude compared to the conventional Rashba…
Visibility study of graphene multilayer structures
Guoquan Teo, Haomin Wang, Yihong Wu +4
The visibility of graphene sheets on different types of substrates has been investigated both theoretically and experimentally. Although single layer graphene is observable on vari…
Fast switchable electro-optic radial polarization retarder
B. C. Lim, P. B. Phua, W. J. Lai +1
A fast, switchable electro-optic radial polarization retarder (EO-RPR) fabricated using the electro-optic ceramic PMN-PT is presented. This EO-RPR is useful for fast, switchable ge…
