  • Development of broadband, high-power, and tunable light sources for OCT, requires novel approaches to achieve wide bandwidth semiconductor lasers and amplifiers operating in a wide range of wavelengths. Novel in plane semiconductor sources and amplifiers will be developed, capitalizing on leading expertise at Tampere University and Superlum Diodes Ltd. In particular, semiconductor optical amplifiers (SOA) with optical bands approaching 150 nm and high saturation powers will open novel avenues in a multitude of directions for the technology of swept sources. SUP seeks the improvement of their SOA bandwidth by:
  • concatenation of multiple quantum-well (MQW) structures with different, non-overlapping spectral gain peaks;
  • extending the anti-reflection coating bandwidth of SLDs chips;
  • modifying the geometry of the SLD chips.

Education

  • 2011 – June 2015 National University of Science and Technology Moscow Institute of Steel and Alloys (NUST MISiS) – Bachelor of Material Science
  • 2015 – June 2017 National University of Science and Technology Moscow Institute of Steel and Alloys (NUST MISiS) – Master of Material Science
  • During the last 4 years, I have been working at Ltd Opton, I have been studying superluminescent diodes (SLDs) in the spectral range of 635 – 690 nm. We were able to create a tunable laser with a tuning range of 673-690 nm and a power of 10 mW. And also demonstrate a broadband light source with a spectrum width of up to 30 nm centered at about 665 nm.
