Creating Light-Made Waveguides with Structured Optical Beams in Nonlinear Kerr Media
M. Zamboni-Rached, K. Z. Nóbrega, Mo Mojahedi
While in linear optics the subject of structured light has been a fruitful field of both theoretical and applied research, its development in the arena of nonlinear optics has been…

Broadside High Index Dielectric Beam Routing
Arnab Dewanjee, Stewart Aitchison, Mo. Mojahedi
We propose a technique to control the beam direction of a dielectric optical micro-prism structure by properly designing its geometry. We show that by selectively choosing the slop…

An Efficient and Compact Excitation of Surface Plasmons Using a Si Gable Tip
Arnab Dewanjee, M. Z. Alam, J. Stewart Aitchison +1
We propose a novel technique to efficiently excite a surface plasmon polariton (SPP) mode at a gold-glass interface by exploiting the near field excitation of an engineered high in…
