Implementation of polarization-encoded quantum Toffoli gate
摘要： Optics plays an important role in data processing. In this context, optical nonlinear material is very useful for superfast switching operations. Again polarization-based encoding and decoding technique plays a convenient way for data processing. In this paper, a new method to implement a quantum Toffoli gate with the active use of optical nonlinear material and polarization-based encoding technique is reported.

Hourglass nonlinear photonic crystal cavity for ultra-fast all-optical switching
摘要： In this paper, a new design of an ultra fast all optical switch based on a new photonic crystal cavity combined with Kerr effect is proposed and its performance is studied. Numerical methods such as plane wave expansion (PWE) and finite difference time domain (FDTD) are used to perform simulations and study the optical properties of the proposed switch. Switching from ON to OFF status occurred when the resonant wavelength is shifted due to Kerr effect. The simulation results show that switch has a high-speed response of ~15ps and since it has an ultra-small size of 273.24 μm2, it has a potential to be used in integrated optical-circuits.

[IEEE 2018 19th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM) - Erlagol (Altai Republic), Russia (2018.6.29-2018.7.3)] 2018 19th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM) - Examination of Physical Phenomena and Processes in the Magnetophotonic Composite Media. Magnetophotonics Material Medium
摘要： The development of radioelectronics and informative–and–communicative technologies of the XXI century is associated with the transmission of ever increasing volume of data and is oriented to use of subTHz and THz bands – SHF, EHF, and HHF (0.1 – 10 THz). Elements and devices of these bands can be conditionally divided into 2 levels: up to 1THz electronic equipments are effectively uses, over 1 THz –are photonic devices. The development of photonic technologies is of increasing importance both in the telecommunicative and in the space communication systems. In this report the physical phenomena and processes occurring in magnetooptical (magnetophotonic) composite material media capable of optimally ensuring their efficiency have been investigated to create new element baseline for domestic radioelectronics. The creation of new–generation functional devices capable of operating in subTHz and THz frequency bands will entail the rapid development of telecommunications.
