Semiconductor waveguide quantum well lasers
Jonathan R. C. Woods, Jon Gorecki, Roman Bek +8
Coherent laser arrays compatible with silicon photonics are demonstrated in a waveguide geometry in epitaxially grown semiconductor membrane quantum well lasers transferred on subs…
Anomalous Resonance Frequency Shift in Liquid Crystal-Loaded THz Metamaterials
Eleni Perivolari, Vassili A. Fedotov, Janusz Parka +2
Babinet complementary patterns of a spectrally tunable metamaterial incorporating a nematic liquid crystal are normally assumed to exhibit the same tuning range. Here we show that…
Multiple double-metal bias-free terahertz emitters
Duncan McBryde, Paul Gow, Sam A. Berry +3
We demonstrate multiplexed terahertz emitters that exhibits 2 THz bandwidth that do not require an external bias. The emitters operate under uniform illumination eliminating the ne…
Surface domain engineering in congruent lithium niobate single crystals: A route to submicron periodic poling
Alessandro C. Busacca, Collin L. Sones, Vasilis Apostolopoulos +2
We describe a technique for surface domain engineering in congruent lithium niobate single crystals. The method is based on conventional electric-field poling, but involves an inte…
Simulation of metallic nanostructures for emission of THz radiation using the lateral photo-Dember effect
Duncan McBryde, Mark E. Barnes, Geoff J. Daniell +6
A 2D simulation for the lateral photo-Dember effect is used to calculate the THz emission of metallic nanostructures due to ultrafast diffusion of carriers in order to realize a se…
Terahertz emission by diffusion of carriers and metal-mask dipole inhibition of radiation
M. E. Barnes, D. McBryde, G. J. Daniell +7
Terahertz (THz) radiation can be generated by ultrafast photo-excitation of carriers in a semiconductor partly masked by a gold surface. A simulation of the effect taking into acco…
