General information

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

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

Scientific results:

  • Our researchers have developed new synthetic approaches to the production of  colloid perovskite nanocrystals with core-shell structure of the types CsPbBr3-CdS and CsPbBr3-SiO2. The nanocrystals demonstrated a high stability of structural and optical properties in water solutions and the effect of suppression of Auger recombination of photo-excited charge carriers due to the presence of a shell. Later CsPbBr3-SiO2 nanocrystals were used for the two-photon imaging of biological objects, while CsPbBr3-CdS was used for the self-assembly of micron-size superlattices demonstrating photoluminescence that is stable over time when excited by UV radiation.
  • A method has been developed for the synthesis of CsPbBr3 perovskite nanocuboids supporting Mie optical resonances. The produced nanocuboids were applied to metal-dielectric substrates, which allowed to observe low-threshold laser generation in perovskite resonators. We confirmed the polaritonic nature of laser generation. It was found that single-mode polariton laser generation occurs in a nanocuboid with a size of an edge amounting to 190 nm.
  • Using the method of recrystallizing thin CsPbBr3 polycrystalline films under pressure with sizes of perovskite grains ranging from 0.1 to 0.2 μm, we produced films with enhanced  crystallinity of grains of larger dimensions (up to 17 μm). Films with a width of 100 nm demonstrated a record-high optical amplification coefficient for this type of perovskite, 12900 cm-1. From this film we produced an array of microdisks that manifested low-threshold (14 µJ cm-2) and high-Q (Q = 1800) laser generation.
  • We have produced flexible visualizers of infrared laser radiation based on silicon thread-like microcrystals planted into a polymer membrane. A new platform has been developed on the basis of perovskite nano- and micro-lasers integrated with a one-dimensional photonic crystal to control the orientation of laser radiation and its propagation at the microscale. We developed prototypes of perovskite-based detector of terahertz laser radiation. We developed and tested a model of nonlinear optical heating of a carbon particle during its interaction with laser radiation at a frequency close to the resonance frequency of the particle.   
  • Our researchers have demonstrated the efficiency third harmonic generation in arrays of silicon thread-like micro-crystals encapsulated in a polymer membrane. The arrays were produced using lithography (with the use of polystyrene microspheres) and dry etching of the silicon substrate. It has been theoretically and experimentally determined that optical resonances supported by thread-like crystals determine the spectral characteristics of third harmonic generation. At the same time, the intensity of generation signal at the resonance wavelength is several times higher in comparison with the corresponding  value at wavelengths closer to the resonance wavelength. We determined the correlation between the intensity of generation and the length of pumping wave for arrays of thread-like crystals. It has been shown that the produced composite membranes  efficiently transform infrared radiation in a wide spectral range (λ = 1200-1900 nm) to visible light. At the same time, the membranes are flexible and semi-transparent for infrared radiation passing through them.
  • We have integrated perovskite nano- and microlasers with a one-dimensional photonic crystal that supports the efficient excitation and long-distance propagation of Bloch surface waves (BSW). The photonic crystal ensures the propagation of coherent radiation of a perovskite laser across distances of up to 50 μm. The observed experimental results are in agreement with numerical computations that confirm that the efficiency of pumping laser radiation into BSWs is over 16%. It has been found that the orientation of BSWs depends on the length of the perovskite resonator and on the efficient refractive index of  BSWs. Unlike perovskite nanolasers with subwave dimensions, microlasers with dimensions of the edge exceeding the length of the radiated wave support narrowly-focused BSWs with an angle of divergence of 9±2°. Moreover, the  planar isotropic of  BSW dispersion allows to shift and direct the beam of laser generation depending on the orientation of the beam of exciting radiation. .
  • For the organo-inorganic halide perovskites MAPbI3 and MAPbBr3 we have demonstrated the detection of terahertz pulses propagating in free space. The ultra-fast tuning of conductivity that occurs in perovskite microcrystals and polycrystalline films when they are excited by a femtosecond laser allows to efficiently register terahertz radiation. The results demonstrate the suitability of halide perovskites for producing photoconducting detectors of terahertz radiation and the possibility of their scaling.
  • We have developed a new theoretical approach to optimizing the process of nonlinear optical heating of a silicon resonator. The proposed system based on the mode of a ultraresonator in cylindrical silicon particles allows to efficiently transform light falling on a particle into heat given that the frequency of the falling radiation is tuned to suit the frequency of the mode. We determined a bistability mode under conditions of optical heating at an intensity of incident radiation of about  1 mW/μm2.

  • Employees of the Laboratory made presentations at the «SLALOM» scientific school (28-30 June 2021, Vladivostok, Russia).
  • In 2021-2022 we conducted six internships of the Laboratory’s postgraduate students at Bilkent University (Turkey).
