Transmit Power Optimization in Optical Coherent Transmission Systems: Analytical, Simulation, and Experimental Results
Ramin Hashemi, Mehdi Habibi, Hamzeh Beyranvand +3
In this paper, we propose to use the discretized version of the so-called Enhanced Gaussian Noise (EGN) model to estimate the non-linearity effects of fiber on the performance of o…

Plano-concave microlenses with epsilon-near-zero surface-relief coatings for efficient shaping of nonparaxial optical beams
Mahin Naserpour, Carlos J. Zapata-Rodriguez, Mahdieh Hashemi
Epsilon-near-zero (ENZ) materials, including artificial metamaterials, have been advanced to mold laser beams and antenna-mediated radiated waves. Here we propose an efficient meth…

Metacoatings for wavelength scale, high NA plano-concave focusing lenses
Mahin Naserpour, Carlos J. Zapata-Rodríguez, Carlos Díaz-Aviñó +1
We design plano-concave silicon lenses with coupled gradient-index plasmonic metacoatings for ultrawide apertured focusing utilizing a reduced region of . The anomalou…
