Crosstalk Limiting Schedulers in AWG Based Optical Switches [PDF]

open access: yes2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
Optical switching fabrics are gaining interest as in multi Terabit switching devices; the advantages over their electronic equivalents are mainly their information density and power consumption. Arrayed Waveguide Gratings (AWGs) are promising optical devices proposed by the academic and industrial community to build optical switching fabrics.

Suppression of the optical crosstalk in a multi-channel silicon photomultiplier array [PDF]

open access: yes, 2021
We propose and study a method of optical crosstalk suppression for silicon photomultipliers (SiPMs) using optical filters. We demonstrate that attaching absorptive visible bandpass filters to the SiPM can substantially reduce the optical crosstalk ...

On optical crosstalk between fly rhabdomeres [PDF]

open access: yesBiological Cybernetics, 1975
In a fly retinula light may be transferred among the rhabdomeres. It is estimated that the light from a point source imaged on the axis of a rhabdomere may eventually be transferred completely to a neighbouring rhabdomere. However, the effect on the sensitivity of this latter rhabdomere will remain small, owing to the fact that the light transfer ...

Design of planar waveguide directional couplers with arbitrary modal electric field

open access: yesIET Optoelectronics, 2022
The purpose of this work is to present a method for designing planar waveguide couplers of arbitrary modal electric field distributions. The idea here is to create couplers with unusual electric fields, which confine in one planar waveguide.

Design and Simulation of Thermo-Optic Phase Shifters With Low Thermal Crosstalk for Dense Photonic Integration

open access: yesIEEE Access, 2020
We investigate and demonstrate the thermal crosstalk problem in integrated photonic circuits with metal and silicon doped heaters. Further, we illustrate that due to the localized heating effect, integrated doped heaters are out-performed in terms of ...
