Information about the research project:

The size of optical components (waveguide, resonators, etc) is fundamentally limited by diffraction and it is a significant challenge to design subwavelength light sources using only dielectric materials. At the same time, metals, such as gold and silver, exhibit negative permittivity at optical frequencies and the penetration depth of the electromagnetic field into them does not exceed a few tens of nanometers. This gives an opportunity to significantly reduce the mode volume using metal coated structures [Appl. Phys. Lett. 96, 251101 (2010)]. However, even in this case, the mode volume is diffraction-limited [Opt. Express 21, 4728 (2013)], which does not allow to reduce the actual size of optical components to that of electronic and merge optics and electronics on a single chip.

One can overcome this fundamental limitation by switching from photons to surface plasmon polaritons (SPPs), surface electromagnetic waves strongly confined to the metal surface. Accordingly, the mode size can be reduced by orders of magnitude below the classical diffraction limit. However, the SPP losses in metal-semiconductor structures are typically as high as several thousands of inverse centimeters, since a considerable amount of the SPP field is concentrated in the metal that results in Joule losses. To design a truly nanoscale light source based on a strongly confined SPP mode, one needs to compensate not only moderate radiation losses but also very high Joule losses. This could be done with optical pumping [Nat. Mater. 10, 110-113 (2010)] if it were not so inefficient and did not require external high-power bulky pump lasers. In this regard, electrically pumped nanolasers integrated on a chip must be developed.

The focus of this project is development of novel schemes for surface plasmon polariton amplification in deep-subwavelength metal-semiconductor-insulator cavities using compact electrical pumping, which will be the basis for the further design of efficient nanoscale light sources. To address this problem, the candidate will work at the interface between nanophotonics and semiconductor physics. Special attention will be given to the interplay between electrical and optical properties of the nanostructures, injection efficiency and modal losses of the SPP mode, contact electrical resistivity and Joule heating losses. Conceptually, the project is directly related to our recent works published in Nano Letters (2012, doi:10.1021/nl300540x), Optics Express (2015, doi:10.1364/OE.23.019358), Optics Letters (2012, doi:10.1364/OL.37.000404) and ACS Photonics (2015, doi:10.1021/acsphotonics.5b00449).

The period of employment:

24 months

Important dates:


The position will remain open until filled. The selected applicant is expected to start his job no later than July 2016.

Special requirements for the candidate:

The candidate should have a strong background in nanophotonics and/or semiconductor physics and an international experience. Prior experience in any of the following areas is highly desirable: nanophotonic/plasmonic waveguides and cavities, semiconductor lasers, optoelectronics and photovoltaics, electron and hole transport in semiconductor heterostructures, numerical simulation of semiconductor nanoelectronic devices, numerical simulation of optical nanostructures. The candidate is expected to have excellent skills in English (both orally and in writing) as well as excellent collaboration skills.

Salary:

75 000 RUB (2016)

80 000 RUB (2017-2018)

Additional bonuses are possible depending upon achievements. If necessary, an accomodation in MIPT campus can be provided free of charge.
