Metamaterial-based octave-wide terahertz bandpass filters
Ali Maleki, Avinash Singh, Ahmed Jaber +5
We present octave-wide bandpass filters in the terahertz (THz) region based on bilayer-metamaterial (BLMM) structures. The passband region has a super-Gaussian shape with a maximum…
Single-pulse time-resolved terahertz spectroscopy of sub-millisecond time dynamics
Nicolas Couture, Wei Cui, Markus Lippl +7
Slow motion movies are not only fascinating to watch, they also allow us to see intricate details of the mechanical dynamics of complex phenomena. If the images in each frame are r…
Physics graduate student employment: what we can learn from professional social media
Erin M. Tonita, Ludmila Szulakowska, Joshua Baxter +3
In this study, we investigated the employment status of recent University of Ottawa physics MSc and PhD graduates, finding that 94% of graduates are either employed or pursuing fur…
Ultra-high-Q resonances in plasmonic metasurfaces
M. Saad Bin-Alam, Orad Reshef, Yaryna Mamchur +8
Plasmonic nanostructures hold promise for the realization of ultra-thin sub-wavelength devices, reducing power operating thresholds and enabling nonlinear optical functionality in…
Mechanistic insight into the limiting factors of graphene-based environmental sensors
Jean-Michel Guay, Ranjana Rautela, Samantha Scarfe +11
Graphene has demonstrated great promise for technological use, yet control over material growth and understanding of how material imperfections affect the performance of devices ar…
Portable and wireless signal transducer for field testing of environmental sensors based on 2D materials
Nicholas Dallaire, Yicong Zhang, Xiangwen Deng +7
In this paper we present the design and fabrication of a portable device for environmental monitoring applications. This novel hand-held apparatus monitors the changes in the resis…
Multi-resonant high-Q plasmonic metasurfaces
Orad Reshef, Md Saad-Bin-Alam, Mikko J. Huttunen +5
Resonant metasurfaces are devices composed of nanostructured sub-wavelength scatterers that generate narrow optical resonances, enabling applications in filtering, nonlinear optics…
Shot noise reduced terahertz detection via spectrally post-filtered electro-optic sampling
Michael Porer, Jean-Michel Ménard, Rupert Huber
In ultrabroadband terahertz electro-optic sampling, spectral filtering of the gate pulse can strongly reduce the quantum noise while the signal level is only weakly affected. The c…
Non-thermal separation of electronic and structural orders in a persisting charge density wave
M. Porer, U. Leierseder, J. -M. Ménard +7
The simultaneous ordering of different degrees of freedom in complex materials undergoing spontaneous symmetry-breaking transitions often involves intricate couplings that have rem…
