Scientists Develop Bacterium-Sized Microlaser
An international team of researchers, including scientists from HSE University–St Petersburg, has developed microlasers that emit deep-ultraviolet light at a wavelength of 255 nanometres. The devices operate at room temperature, and the smallest of them measures just two micrometres in diameter—roughly the size of a bacterium. These microlasers could be used in sensors, spectroscopic systems, photonic chips, and communication devices. The paper has been published in Optics & Laser Technology.
'Scientist's Code': Alexey Zhukov on First Quantum Dot Laser, Optoelectronics and Alferov's Luck
The admissions to bachelor's and master's programmes in Physics at HSE University-St Petersburg are still ongoing. Today 'Scientist's Code' introduces you to the head of the department to which these programmes belong. Please meet Alexey Zhukov, Corresponding Member of the Russian Academy of Sciences, Doctor of Physics and Mathematics and Head of the Department of Physics. We discussed with the researcher why it is important to switch to optical data transmission, where quantum cascade lasers are required and why Albert Einstein was a genius.
