In our another work, we previously showed that one photon is enough to control an optical polariton transistor, which cannot be implemented in any other optical system,” said Denis Sannikov, the first author of the work, the deputy head of the Hybrid Photonics Laboratory at the Skoltech ...

In the case of polariton condensation, an off-resonant optical beam creates a reservoir of hot excitons. Through Coulomb and phonon scattering events these then relax towards the so-called bottleneck region close to the top of the LPB. From there, polaritons undergo stimulated scattering towards th...
Whereas essential all-optical transistor functionalities were demonstrated across a range of platforms, utilising them to implement a complete Boolean logic gate set and in particular negation, i.e. switching off an optical signal with another, weaker, optical signal, poses a major challenge. Here,...
1a. The light beam is coupled to a surface plasmon polariton (SPP) mode propagating at the interface between the metal and the atoms. As a consequence, the atoms interact with the eva- nescent tail of the SPP mode. The device consists of a glass prism coated by a 3-nm adhesion layer...
(NA = 0.42). We collect the real space polariton photoluminescence (PL), directly proportional to the condensate density, in transmission geometry and spectrally filter it from the excitation laser. We denote the horizontal and vertical momentum space coordinates ask = (kx, ky), ...
An all-optical computer has remained an elusive concept. To construct a practical computing primitive equivalent to an electronic Boolean logic, one should utilize nonlinearity that overcomes weaknesses that plague many optical processing schemes. An adv
transistors, the CPA provides most of the essential features of an all-optical transistor like operating at room temperature, working by using ultra-low power, cascadability, fast response and integrability. The suggested all-optical fiber-based transistor can be exploited in quantum computing ...
