Time-domain chromatic dispersion (CD) equalization using finite impulse response (FIR) filter is now a common approach for coherent optical fiber communication systems. The complex weights of FIR filter taps are calculated from a truncated impulse response of the CD transfer function, and the modulus of the complex weights is constant. In our work, we take the limited bandwidth of a single chan...

This paper provides a mathematical approach to the study of chromatic aberration in metalenses. It is shown that radiation given wavelength refracted according generalized Snell's law, which together with notion envelope, yields existence phase discontinuities. then used establish quantitative measure dispersion metalenses, concluding visible spectrum it has same order magnitude as for standard...

The purpose of this paper is to experimentally study Optical All Pass Filters (OAPF) and optimize the value of distance of origin from poles (r). Using the value of transfer function of optical all pass filter which is of 2 order we found the factor of numerator and denominator. In this work, we took the value of ̳r‘ as 0.660 and the angular position (w0) as 0.390. The power taken as 18dBm. Whe...

This is dedicated to my family and everyone else who helped me along my way just so they could see me succeed. This is also dedicated to the innocent students and faculty who lost their lives at Virginia Tech on April 16, 2007 doing what I am doing now: pursuing a higher education. iv ACKNOWLEDGEMENTS I would like to thank Dr. Ali Adibi for being my advisor, for always being accommodating and w...
