Evaluating the short-term unpredictability of semiconductor lasers subject to multiple time-delayed feedbacks. Vrije Universiteit Brussel
perturbations such as optical feedback can easily trigger various dynamical behaviors like oscillations and
even chaos. The latter proved to be interesting for applications in secure communications or cryptography,
however optimizing the chaotic behavior remains a challenge. A key feature is the time after which the
chaotic ...
Heterogeneously integrated piezo-electro-mechanical lasers for LiDAR and 6G cellular networks Ghent University
Highly coherent – that is narrow linewidth - laser sources are at the heart of numerous applications: ranging from terabit per second coherent communication, LiDAR for autonomous driving or driver assistance, to fibre sensing or optical atomic clocks. Yet, in contrast to MEMS sensors, or electroni circuits, the manufacturing of narrow linewidth lasers is not suitable for high volume; fiber lasers, the workhorse for narrow linewidth, rely on ...
Next-generation on-chip modelocked lasers based on novel material combinations and enhanced (non-)linear optical responses (LASMORE) Vrije Universiteit Brussel
nowadays be integrated on tiny chips based on ‘active’ semiconductor material platforms such as the
indium phosphide (InP) platform. On-chip modelocked InP lasers typically consist of an InP
waveguide resonator containing an InP amplifier and a nonlinear-optical InP saturable absorber (SA).
Notwithstanding the major progress made ...
Integrated III-V-on-silicon-nitride mode-locked lasers for frequency comb generation in telecom and frequency metrology applications Ghent University
Optical frequency combs have become a cornerstone of frequency metrology and are now available as commercial systems based on pulsed fiber lasers. Since the Nobel prize in physics was awarded to John L. Hall and Theodor W. Hänsch in 2006, the application space for optical frequency combs has dramatically increased. The use of these combs is currently being studied for the use in ultra-fast acquisition molecular spectroscopy, high-speed and ...
ERC-opvangmandaat: All-optical sub-THz signal filtering with multi-COLOR lasers Vrije Universiteit Brussel
Temporally resolved measurements of the emission pattern of semiconductor lasers Vrije Universiteit Brussel
Pattern Formation in Integrated Lasers for Spectroscopy and Terahertz Wave Generation Ghent University
Ever since their invention in 1961, lasers have been used in an ever-growing number of applications. They have since been miniaturized and can now be integrated on microchips alongside electronic transistors. Yet,most are emitting a single color, while many novel and exciting applications, such as LIDAR and extrasolar planet detection require the simultaneous emission of many different colors.
But forcing multicolor emission, while the ...
Dense wavelength division multiplexed transmitter based on optical injection locking of strained vertical-cavity surface-emitting lasers Vrije Universiteit Brussel
datacentres employ Vertical-Cavity Surface-Emitting lasers (VCSELs), because of their low cost, small footprint, and capability for large-scale fabrication. Additionally, they can be directly modulated with a low modulation voltage so that power consumption can be further reduced. In order to cope with the increasing demands for higher capacity, dense wavelength division ...
