Participation in the Serbian-Chinese conference on the development of artificial intelligence 11.4.2024.
11.4.2024.
On 11.4.2024. our team participated in a conference dedicated to the development of artificial intelligence, organized by the Science Fund of the Republic of Serbia and the National Science Foundation of the Republic of China. The conference aimed to introduce researchers from the two countries and to present previous projects in this field. We thank the Science Fund for the invitation to this interesting scientific event.
Lecture by Dr. Aleksandar Demić, external collaborator on the project
7.4.2024.
On Friday, April 5, starting at 2:15 p.m. in room 313 at the School of Electrical Engineering, Dr. Aleksandar Demić, an external collaborator on the TERALOCK project, held a 2-hour presentation entitled "Development of software for design, dynamics, transport and optimization of quantum cascade laser with reference to parallel programming, machine learning, and neuromorphic computing" for interested students of the Department of Physical Electronics. The idea was to familiarize the students with some of the activities that are carried out within the project, that is, the lecture was one of the activities within the planned dissemination of the project's results.
Scientific visit of the external collaborator Dr. Aleksandar Demić
7.4.2024.
On the occasion of the short-term scientific visit of the external collaborator on the project, Dr. Aleksandar Demić, from the University of Leeds, we held several very productive project meetings in the period from 26.3.- 5.4.2024. in the premises of the School of Electrical Engineering, where we determined what we have achieved so far within the work packages and what needs to be improved in our models. Tasks for the upcoming quarter were distributed at the meetings.
Formal ceremony of promotion of awarded projects from the project cycle "Program of Young researchers - PROMIS 2023"
20.3.2024.
On Wednesday, March 20, 2024, a celebration was held on the occasion of five years of existence of the Science Fund of the Republic of Serbia. During the celebration, the attendees were addressed by the acting director of the Fund for Science Ms. Milica Đurić-Jovičić, PhD, the Minister of Science, Technological Development, and Innovation, Ms. Jelena Begović, PhD, as well as representatives of the European Union and the World Bank. At the celebration, PIs of the approved projects from the PROMIS 2023 call and projects that were awarded and received two-year funding from the Science Fund of the Republic of Serbia were especially highlighted. The celebration was attended by the PI of the TERALOCK project, Dr. Nikola Vuković.
Presentation of the project results on the 17th Photonics Workshop at Kopaonikski resort
15.3.2024.
From March 10 to 14, 2024, the 17th Photonics Workshop was held at Kopaonik ski resort. The conference program is available at this link. On Wednesday, March 13, 2024, our team presented a paper entitled "Optical and transport properties of THz quantum cascade heterostructures", which is in the book of abstracts available at the following link. The presentation included our latest project results related to work package 1, which were published in open access in SCI-listed journals during February and March 2024. (see the Published Papers section below).
The kick-off meeting
9.1.2024.
In the meeting room of the School of Electrical Engineering, the TERALOCK project team held the kick-off meeting on Tuesday, January 9, 2024. PI distributed the tasks to the members for the first quarter of the project and presented an overview of the half-yearly goals, milestones, and deliverables. The dynamics of live and online meetings with an external collaborator from the University of Leeds were agreed upon.
Project information
Acronym: TERALOCK
As part of the TERALOCK project, a theoretical investigation of the possibility of generating stable trains of ultra-short (fs–ps) pulses of terahertz radiation using a quantum cascade laser operating in passive mode-locking mode will be carried out. Potential applications are in spectroscopy, the study of light-matter interaction, metrology and ultra-fast communications.
The terahertz part of the electromagnetic spectrum is very attractive for various technological applications, some of which have been very successfully implemented. However, an adequate semiconductor platform still lacks that would enable intensive ultrafast pulse generation, which would advance ultrashort time duration measurements, nonlinear photonics, coherent matter control, and frequency comb synthesis for high-precision metrology and spectroscopy.
The terahertz quantum cascade laser has experienced remarkable development since its first demonstration twenty years ago and is considered a potential solution to overcome the aforementioned technological problem. On the other hand, achieving intense and ultrashort pulses with this device has limitations due to the fast gain recovery time preventing passive mode locking, which is the standard way of generating short pulses. The TERALOCK project aims to investigate passive mode locking theoretically using a graphene-saturable absorber.
