The effect of electric field on multiple exciton generation in lead chalcogenide nanocrystals
Mahdi Gordi, Mohammad Kazem Moravvej-Farshi, Hamidreza Ramezani
Unique properties of lead chalcogenides have enabled multiple exciton generation (MEG) in their nanocrystals that can be beneficial in enhancing the efficiency of the third generat…
Perfect Impedance-Matched Isolators and Unidirectional Absorbers
J. M. Lee, Z. Lin, H. Ramezani +4
A broad-band reflectionless channel which supports unidirectional wave propagation originating from the interplay between gyrotropic elements and symmetrically placed gain and loss…
PT-Symmetric Talbot Effects
Hamidreza Ramezani, D. N. Christodoulides, V. Kovanis +2
We show that complex PT-symmetric photonic lattices can lead to a new class of self-imaging Talbot effects. For this to occur, we find that the input field pattern, has to respect…
