, 2023 Vertical cavity surface emitting lasers (VCSEL) are of great interest for photonic and telecom applications, however challenges in fabrication of efficient VSCEL GaN devices are yet to be resolved. In this work we present a study of micro-photoluminescence (PL) emission from a novel InGaN quantum well (QW) emitting structure with integrated micro ...

Laser &Photonics Reviews, EarlyView.Room‐temperature lower‐polariton‐like lasing is realized in an InGaN/GaN thin‐film ridge cavity with lateral distributed Bragg reflectors. Near‐field optical microscopy distinguishes the transverse side‐DBR‐confined mode from a longitudinal photon‐like mode, while simulations reproduce their spatial profiles.

Drive‐Efficient GHz‐Rate Binary‐State Updates Enabled by VCSEL Polarization Switching
Laser &Photonics Reviews, EarlyView.Photonic computing needs a compact node that can hold a binary state and update it fast. A vertical‐cavity surface‐emitting laser biased at its polarization‐switching point could serve as one: its two orthogonal linear polarizations are the two states, and a small electrical drive is enough to move the output from one state to the other at gigahertz ...

The DBR Methodology for the Study of Context in Learning [PDF]
, 2017 In the Design-Based Research (DBR) methodology, the process is as important as the product, and each iteration is considered a sub-result leading to the next one. This methodology is being used in the TEEC project, to both study and elaborate solutions for Learning in Context.
