Young scientists from ITMO University have developed a new type of nanoscale light sources based on halide perovskites. The nanosources are subwavelength nanoparticles which serve both as emitters and nanoantennas capable of amplifying light emission inherently without need for additional devices. Moreover, perovskites enable tuning of emission spectrum throughout a visible range by varying the composition of the material. This makes the new nanoparticles a promising platform for creating compact optoelectronic devices such as optical chips, light-emitting diodes, or sensors. The results were published in Nano Letters, one of the leading journals on nanophotonics.
In 2016, ITMO's Department of Nanophotonics and Metamaterials received a grant to launch the "Photonics and Optoelectronics of Nanostructured Perovskite Materials" research center. Anvar Zakhidov, a professor from the Texas University in Dallas, collaborates with Sergei Makarov from ITMO's Department of Nanophotonics and Metamaterials as head of its new Laboratory of Hybrid Nanophotonics and Optoelectronics. In an interview with our news portal, the professor spoke about how he got interested in metamaterials, the new technologies for producing perovskite patterns and the laboratory's recent results
Sergei Makarov and Alexander Krasnuk, senior researchers at the Department of Nanophotonics and Metamaterials received the Foundation for Support of Education and Science (Alferov's Foundation) award for their research on non-linear tunable semiconductor and hybrid nanoantennas. According to the jury, their main scientific achievement was the development of a new platform for photonic devices based on dielectric nanoantennas in optical band, as well as the use of femtosecond laser technologies in creation of ultrafast optical nanodevices. In an interview with our newsportal, Sergei Makarov talked about new optical modulators and the work of the recently founded Laboratory of Hybrid Nanophotonics and Optoelectronics.
On one hand, solar panels are a green solution, but on the other, they are very expensive and not very effective. However, cutting expenses on them will increase the popularity of this alternative energy source. ITMO’s PhD student Mikhail Omelyanovich is working on reducing the cost for solar panels using perovskites and laser ablation. ITMO.NEWS talked to Mikhail about his development.
The "Dream Tasks" of Photonics: Sergei Makarov and Anvar Zakhidov Share about ITMO’s Collaboration on Hybrid Perovskites
In the end of last September, ITMO University and the University of Texas at Dallas won a big grant, which will be used to build Russia's first laboratory for creating new optoelectric devices based on hybrid perovskites. So, how will the unique laboratory work, what are flexible lasers and is it possible to create a teraherz device that can see trough walls? Learn this and more from our article.
