Blue-shift ultrasensitivity using rhombus-shaped plasmonic crystal on Si3N4 membrane

Dordaneh Etezadi, Mahdi Tamizifar, Bahareh Ghadiani, Yasaman Jahani, Foziyeh Sohrabi, Ershad Mohammadi

Harnessing ultrasensitivity from optical structures to detect tiny changes in the targeted samples is the main goal of scientists in the field of sensor design. In this study, an uncommon rhombus-shape plasmonic structure is proposed for providing blue-shi ...

Spectrally Selective Mid-Wave Infrared Detection Using Fabry-Perot Cavity Enhanced Black Phosphorus 2D Photodiodes

Christophe Ballif, Quentin Thomas Jeangros, Wei Yan

Thin two-dimensional (2D) material absorbers have the potential to reduce volume-dependent thermal noise in infrared detectors. However, any reduction in noise must be balanced against lower absorption from the thin layer, which necessitates advanced optic ...

Crystal Phase Engineering in III-V Semiconductor Films: from Epitaxy to Devices

Philipp Staudinger

Crystal phase engineering is an exciting pathway to enhance the properties of conventional semiconductors. Metastable SiGe presents a direct band gap well suited for optical devices whereas wurtzite (WZ) phosphide alloys enable efficient light emission in ...

Scalar analytical expressions for the field dependence of Zernike polynomials in asymmetric optical systems with circular symmetric surfaces

Toralf Scharf, Alessandro Grosso

In this paper we derive scalar analytical expressions describing the full field dependence of Zernike polynomials in optical systems without symmetries. We consider the general case of optical systems constituted by arbitrarily tilted and decentered circul ...

Single crystal diamond gain mirrors for high performance vertical external cavity surface emitting lasers

Niels Quack, Grigore Suruceanu, Alexandru Mereuta, Andrei Caliman, Pascal Gallo, Gergely Huszka, Mehdi Naamoun

We report on the design, fabrication and optical performance of gain mirrors in single crystal diamond substrates for vertical external cavity surface emitting lasers (VECSELs). VECSELs have gained attention recently due to their potential for high emissio ...

Fundamentals and perspectives of ultrafast photoferroic recording

Anna Pogrebna

The ability to switch ferroics (ferro-, ferri-, antiferromagnets, ferroelectrics, multiferroics) between two stable bit states is one of the keystones of modern data storage technology. Due to many new ideas, originating from fundamental research during th ...

Broadened Bandwidth Amplified Spontaneous Emission from Blue GaN-Based Short-Cavity Superluminescent Light-Emitting Diodes

Jean-François Carlin, Denis Martin, Nicolas Grandjean, Raphaël Butté, Hua Zhang, Ching-Wen Shih

We report broad bandwidth blue superluminescent light-emitting diodes (SLEDs) based on a short-cavity active region. The dependencies of amplified spontaneous emission (ASE) output power and gain bandwidth on cavity length were investigated in devices whos ...

Advanced Diamond Microfabrication for Microoptics and Photonics

Marcell Kristof Kiss

Diamond is an exceptional material - hard, stiff, transparent, which makes it ideal for the fabrication of optical and mechanical systems that take advantage of these properties. Diamond is not only "better", but it offers the possibility of integrating br ...

Short cavity InGaN-based laser diodes with cavity length below 300 mu m

Jean-François Carlin, Denis Martin, Nicolas Grandjean, Raphaël Butté, Hua Zhang, Ching-Wen Shih

We report on a practical method for developing InGaN-based edge emitting laser diodes of cavity length down to 45 mu m. Samples consisting of one uncoated cleaved facet and one etched facet coated with a high-reflectivity (HR) dielectric distributed Bragg ...

Resonant Waveguide Gratings for Color-Selective Diffraction

Giorgio Quaranta

Resonant waveguide gratings (RWGs), also known as guided mode resonant (GMR) gratings or waveguide-mode resonant gratings, are dielectric structures where these resonant diffractive elements benefit from lateral leaky guided modes and can operate from UV t ...
