In this paper, we optimize the geometries of some 2D photonic crystal waveguides to increase

their single-mode bandwidths for TE and TM polarizations. Using the Plane Wave Expansion

(PWE) method combined with optimization algorithm, we...

Quantum technology and quantum information is beginning to provide a different computing paradigm and quantum photonics is one of the emerging technologies in realizing quantum computers. There are a number of quantum gates which have been...
