Analytical Boundary-Based Method for Diffraction Calculations
Eitam Luz, Er'el Granot, Boris Malomed
We present a simple method for calculation of diffraction effects in a beam passing an aperture. It follows the well-known approach of Miyamoto and Wolf, but is simpler and does no…
Making the PT symmetry unbreakable
Vitaly Lutsky, Eitam Luz, Er'el Granot +1
It is well known that typical PT-symmetric systems suffer symmetry breaking when the strength of the gain-loss terms exceeds a certain critical value. We present a summary of recen…
Analytical Solutions for Beams Passing Apertures with Sharp Boundaries
Eitam Luz, Er'el Granot, Boris A. Malomed
An approximation is elaborated for the paraxial propagation of diffracted beams, with both one- and two-dimensional cross sections, which are released from apertures with sharp bou…
Fundamental dispersion limit for spectrally bounded On-Off-Keying communication channels
Er'el Granot
The fundamental dispersion limit for optical communication based the On-Off-Keying format is calculated. It is shown both analytically and with numerical simulations that an OOK op…
Partial Differential Phase Shift Keying - Theory and Motivation
Er'el Granot, Shalva Ben-Ezra
Recently, many evidences demonstrate that partial Differential Phase Shift Keying (i.e., when the delay inside the Delay Interferometer is shorter than the symbol period) can parti…
The transition from the ballistic to the diffusive regime in a turbid medium
Andre Yaroshevsky, Ziv Glasser, Er'el Granot +1
By varying the absorption coefficient and width of an intralipid- India ink solution in a quasi one-dimensional experiment, the transition between the ballistic and the diffusive r…
Reconstructing the impulse response of a diffusive medium with the Kramers-Kronig relations
Er'el Granot, Shmuel Sternklar
The Kramers-Kronig (KK) algorithm, useful for retrieving the phase of a spectrum based on the known spectral amplitude, is applied to reconstruct the impulse response of a diffusiv…
Narrow Spectral Response of a Brillouin Amplifier transmission channel
Shmuel Sternklar, Er'el Granot
We investigate the spectral response of a Brillouin amplifier in the frequency regime within the SBS bandwidth. This is done by amplitude modulating the pump with a low frequency,…
Limitations to bit-rate and spatial capacity of an optical data transmission channel
Er'el Granot, Shmuel Sternklar
The maximum bit-rate of a slab waveguide is ultimately determined by the waveguide dispersion. We show that while the maximum bit rate in a waveguide is inversely proportional to t…
