A Space-Time Knife-Edge In Epsilon-Near-Zero Films for Ultrafast Pulse Characterization
Adam Ball, Ray Secondo, Dhruv Fomra +5
Epsilon-near-zero (ENZ) materials have shown strong refractive nonlinearities that can be fast in an absolute sense. While continuing to advance fundamental science, such as time v…
Revisiting the Photon-Drag Effect in Metal Films
Jared H. Strait, Glenn Holland, Wenqi Zhu +5
The photon-drag effect, the rectified current in a medium induced by conservation of momentum of absorbed or redirected light, is a unique probe of the detailed mechanisms underlyi…
Surface-Plasmon-Polariton Laser based on an Open-Cavity Fabry-Perot Resonator
Wenqi Zhu, Ting Xu, Amit Agrawal +1
Recent years have witnessed growing interest in the development of small-footprint lasers for potential applications in small-volume sensing and on-chip optical communications. Sur…
Flat Lens Criterion by Small-Angle Phase
Peter Ott, Mohammed H. Al Shakhs, Henri J. Lezec +1
We show that a classical imaging criterion based on angular dependence of small-angle phase can be applied to any system composed of planar, uniform media to determine if it is a f…
An Efficient Large-Area Grating Coupler for Surface Plasmon Polaritons
Stephan T. Koev, Amit Agrawal, Henri J. Lezec +1
We report the design, fabrication and characterization of a periodic grating of shallow rectangular grooves in a metallic film with the goal of maximizing the coupling efficiency o…
Surface plasmon polariton modes in a single-crystal Au nanoresonator fabricated using focused-ion-beam milling
E. J. R. Vesseur, R. de Waele, A. Polman +3
We use focused-ion-beam milling of a single-crystal Au surface to fabricate a 590-nm-long linear ridge that acts as a surface plasmon nanoresonator. Cathodoluminescence imaging spe…
