Static and dynamic properties of multi-section InGaN-based laser diodes

Jean-François Carlin, Julien Dorsaz, Dmitri Boiko, Nicolas Grandjean, Antonino Francesco Castiglia, Luca Alex Milo Sulmoni, Xi Zeng, Jean-Michel Jacques Lamy

We have studied multi-section InGaN multiple-quantum-well (MQW) laser diodes grown on c-plane freestanding GaN substrate consisting of an absorber section (AS) and an amplifier gain section. As a result of the interplay between external bias applied to the ...

Optical bistability in InGaN-based multisection laser diodes

Jean-François Carlin, Julien Dorsaz, Dmitri Boiko, Nicolas Grandjean, Luca Alex Milo Sulmoni

Optical bistability is observed in cw-operating InGaN-based laser diodes including a saturable absorber (SA) section. The dependence of the light-current hysteresis on the SA section length and reverse bias (VSA) has been studied. An analytical approach is ...

Hybrid polymer microlens arrays with high numerical apertures fabricated using simple ink-jet printing technique

Vahid Fakhfouri, Dmitri Boiko, Jürgen Brugger, Edoardo Charbon, Nils Benedict Brauer, Joo Yeon Kim

Microlens arrays fabricated by a direct ink-jet printing of UV-curable hybrid polymer are reported. A periodic pattern of polymer drops was ink-jet printed on the surface-treated glass substrate and cured in the UV-light. Using this simple technique, we de ...

On the Application of a Monolithic Array for Detecting Intensity-Correlated Photons Emitted by Different Source Types

Dmitri Boiko, Edoardo Charbon

It is not widely appreciated that many subtleties are involved in the accurate measurement of intensity-correlated photons; even for the original experiments of Hanbury Brown and Twiss (HBT). Using a monolithic 4x4 array of single-photon avalanche diodes ( ...

Photonic lattice of coupled microcavities in nonpermanent gravitational field produced by rotation

Dmitri Boiko

Rotation-induced splitting of the otherwise degenerate photonic bands is predicted for a two-dimensional photonic crystal made of evanescently coupled microcavities. The symmetry-broken energy splitting is similar to the Zeeman splitting of atomic levels o ...

Inkjet Printing of SU-8; A Case Study for Microlenses

Alcherio Martinoli, Vahid Fakhfouri, Dmitri Boiko, Jürgen Brugger, Edoardo Charbon, Grégory Mermoud, Nicolas Cantale, Joo Yeon Kim

This paper describes a novel method to fabricate polymer MEMS based on the inkjet printing of SU-8, with a special emphasis on integrated micro-optical lens arrays. Inkjet control parameters are optimized in order to enable a stable and reproducible ejecti ...

Time-correlated Two-photon Fluorescence Imaging with Arrays of Solid-state Single Photon Detector

Cristiano Niclass, Marek Gersbach, Dmitri Boiko, Edoardo Charbon, Carl Petersen

This paper reports on our progress in developing two-photon fluorescence lifetime imaging microscopy (FLIM) based on time-correlated single-photon counting (TCSPC). The core of the system is a 2D array of solid-state single-photon avalanche diodes (SPADs) ...
