Measuring valley polarization in two-dimensional materials with second-harmonic spectroscopy
Yi Wei Ho, Henrique Guimarães Rosa, Ivan Verzhbitskiy +6
A population imbalance at different valleys of an electronic system lowers its effective rotational symmetry. We introduce a technique to measure such imbalance - a valley polariza…
Characterization of the second- and third-harmonic optical susceptibilities of atomically thin tungsten diselenide
Henrique G. Rosa, Ho Yi Wei, Ivan Verzhbitskiy +6
We report the first detailed characterization of the sheet third-harmonic optical susceptibility, , of tungsten diselenide (WSe). With a home-built confocal micr…
Mapping a quantum walk by tuning the coupling coefficient
Kian Fong Ng, Manuel J. L. F. Rodrigues, José Viana-Gomes +2
We present a method to map the evolution of photonic random walks that is compatible with nonclassical input light. Our approach leverages a newly developed flexible waveguide plat…
Mechanically tunable integrated beamsplitters on a flexible polymer platform
James A. Grieve, Kian Fong Ng, Manuel J. L. F. Rodrigues +2
We report the development of a monolithic, mechanically tunable waveguide platform based on the flexible polymer polydimethyl siloxane (PDMS). Such devices preserve single mode gui…
