Giant Tunable Goos–Hänchen Shifts Based on Prism/Graphene Structure in Terahertz Wave Region
IEEE Photonics Journal, 2014 We investigate the giant tunable Goos-Hänchen shifts in prism/graphene structure. It is found that large positive and negative lateral Goos-Hänchen shifts can be easily controlled by adjusting the chemical potential of the graphene, which

Spectrally resolved wave-mixing between near- and far-infrared pulses in gas [PDF]
, 2013 We investigate the nonlinear wave-mixing in gases between intense, short optical pulses and long-wavelength fields (mid infrared and terahertz). We show numerically that the beating between the sum- and difference-frequency generation components can be ...

Measurements of the time-jitter of coherent terahertz synchrotron radiation with a superconducting detector [PDF]
, 2012 We have applied an ultrafast superconducting YBa2Cu3O7-δ (YBCO) detector to study the time jitter of the propagating electron bunches in a synchrotron. The jitter was determined from the coherent terahertz (THz) synchrotron radiation (CSR)
