Temporal super-resolution imaging inspired by structured illumination microscopy
Farshid Shateri, Mehdi Hosseinalizadeh, Zahra Kavehvash
In this paper, a method for increasing the temporal resolution of a temporal imaging system has been developed. Analogously to the conventional spatial imaging systems in which res…
Improved depth resolution and depth-of-field in temporal integral imaging systems through non-uniform and curved time-lens array
Farshid Shateri, Shiva Behzadfar, Zahra Kavehvash
Observing and studying the evolution of rare non-repetitive natural phenomena such as optical rogue waves or dynamic chemical processes in living cells is a crucial necessity for d…
A Simplified Approach to Two-Port Analysis in Feedback
Morteza Fayazi, Ali Fotowat, Zahra Kavehvash
In this paper, a new pedagogical approach for analyzing the negative feedback circuits is proposed. The presented approach is in fact the completed form of the well-known two-port…
Beam Manipulation by Hybrid Plasmonic-Dielectric Metasurfaces
Kamalodin Arik
A hybrid plasmonic-dielectric metasurface is proposed in order to manipulate beam propagation in desired manners. The metasurface is composed of patterned hybrid graphene-silicon n…
High Speed All-optical extended DV-Curve-based DNA sequence alignment utilizing wavelength and polarization modulation
Ehsan Maleki, Hossein Babashah, Somayyeh Koohi +1
This paper presents a novel optical processing approach for exploring genome sequences built upon optical correlator for global alignment and extended DV-curve method for local ali…
Temporal Analog Optical Computing using an On-Chip Fully Reconfigurable Photonic Signal Processor
Hossein Babashah, Zahra Kavehvash, Amin Khavasi +1
This paper introduces the concept of on-chip temporal optical computing, based on dispersive Fourier transform and suitably designed modulation module, to perform mathematical oper…
Diffraction Influence on the Field of View and Resolution of Three-Dimensional Integral Imaging
Zhila Esna Ashari, Zahra Kavehvash, Khashayar Mehrany
The influence of the diffraction limit on the field of view of three-dimensional integral imaging (InI) systems is estimated by calculating the resolution of the InI system along a…
DNA Sequence Alignment by Window based Optical Correlator
Fereshte Mozafari, Hossein Babashah, Somayyeh Koohi +1
In genomics, pattern matching against a sequence of nucleotides plays a pivotal role for DNA sequence alignment and comparing genomes. This helps tackling some diseases, such as ca…
Analog Computing Using Graphene-based Metalines
Sajjad AbdollahRamezani, Kamalodin Arik, Amin Khavasi +1
We introduce the new concept of "metalines" for manipulating the amplitude and phase profile of an incident wave locally and independently. Thanks to the highly confined graphene p…
