P-i-n InGaN homojunctions (10-40% In) synthesized by plasma-assisted molecular beam epitaxy with extended photoresponse to 600 nm
S. Valdueza-Felip, A. Ajay, L. Redaelli +6
We report the influence of the In mole fraction on the material and electrical characteristics of p-i-n InxGa1-xN homojunctions (x = 0.10-0.40) synthesized by plasma-assisted molec…
Design of polarization-insensitive superconducting single photon detectors with high-index dielectrics
Luca Redaelli, Val Zwiller, E. Monroy +1
In this paper, the design of superconducting-nanowire single-photon detectors which are insensitive to the polarization of the incident light is investigated. By using high-refract…
Index-antiguiding in narrow-ridge GaN-based laser diodes investigated by measurements of the current-dependent gain and index spectra and by self-consistent simulation
Luca Redaelli, Hans Wenzel, Joachim Piprek +6
The threshold current density of narrow (1.5 μm) ridge-waveguide InGaN multi-quantum-well laser diodes, as well as the shape of their lateral far-field patterns, strongly depend on…
Effect of the quantum well thickness on the performance of InGaN photovoltaic cells
L. Redaelli, A. Mukhtarova, S. Valdueza-Felip +7
We report on the influence of the quantum well thickness on the effective band gap and conversion efficiency of In0.12Ga0.88N/GaN multiple quantum well solar cells. The band-to-ban…
Design of broadband high-efficiency superconducting-nanowire single photon detectors
Luca Redaelli, Gabriele Bulgarini, Sergiy Dobrovolskiy +4
In this paper several designs to maximize the absorption efficiency of superconducting-nanowire single-photon detectors are investigated. Using a simple optical cavity consisting o…
