General information

Name of the project: Nano-lasers and micro-lasers based on new nano-materials and modern optical architectures

Strategy for Scientific and Technological Development Priority Level: а

Goals and objectives

The objective of this project is the development of new nano-materials and nano-photonic designs for the creation of nano- and micro-lasers of the visible range working at room temperature and, at the same time, possessing ultra-compact dimensions, an ultra-fast mode of modulation of generation, low generation thresholds and working via continuous optical or electrical pumping, that allow to control the polarisation and the spatial characteristics of the generated radiation, and integrated with waveguide systems.  

The implementation of each of the above-mentioned properties of the developed lasers is a separate task linked into one chain of inter-related research cycles that include the theoretical development of of device architectures, the creation of qualitative samples, the conduction of primary experiments, the refinement of theoretical models and the optimisation of the technology, the experimental realisation of the most optimised design with the necessary parameters.

The main objectives are the creation of new theoretical models and the synthesis of new nano-materials, after which we will conduct a multi-stage characterisation of the produced samples, as well as their integration with other nano-photonic designs.

After a repetition of a number of cycles, the project will reach its goal – the creation of nano- and micro-lasers with desired properties.

The practical value of the study
Projected research results: 

  • The creation of nano-materials with record-high values of the optical amplification factor as well as ultra-fast optical response and high electrical and thermal conductivity ratios;
  • New types of ultra-compact nano-resonators that support high Q resonance and laser generation in the visible range at room temperature;
  • Nano - and micro-lasers integrated with waveguide systems (including topologically protected systems), adapted for the visible and the near infrared ranges;
  • The implementation of ultra-fast modulation of nano- and micro-lasers by optimised excitonic non-linearity.
