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…
Two Dimensional Edge Detection by Guided Mode Resonant Metasurface
Amirhossein Saba, Mohammad Reza Tavakol, Parisa Karimi-Khoozani +1
In this letter, a new approach to perform edge detection is presented using an all-dielectric CMOS-compatible metasurface. The design is based on guided-mode resonance which provid…
Spatial Integration by a Dielectric Slab Waveguide and its Planar Graphene-based Counterpart
Farzad Zangeneh-Nejad, Amin Khavasi
Motivated by the recent progress in analog computing [Science 343, 160 (2014)], a new approach to perform spatial integration is presented using a dielectric slab waveguide. Our ap…
Accurate Effective Medium Theory for the Analysis of Spoof Localized Surface Plasmons in Textured Metallic Cylinders
Babak Rahmani, Amirmasood Bagheri, Amin Khavasi
It has been recently demonstrated that textured closed surfaces which are made out of perfect electric conductors (PECs) can mimic highly localized surface plasmons (LSPs). Here, w…
Analog Optical Computing by Half-Wavelength Slabs
Farzad Zangeneh-Nejad, Amin Khavasi, Behzad Rejaei
A new approach to perform analog optical differentiation is presented using half-wavelength slabs. First, a half-wavelength dielectric slab is used to design a first order differen…
