Energy conversion efficiency from a high order soliton to fundamental solitons in presence of Raman scattering
We formulate the energy conversion efficiency from a high-order soliton to
fundamental solitons by including the influence of interpulse Raman scattering
in the fission process. The proposed analytical formula agrees closely with
numerical results of the generalized nonlinear Schrodinger equation as well as
to experimental results, while the resulting formulation significantly alters
the energy conversion efficiency predicted by the Raman-independent inverse
scattering method. We also calculate the energy conversion efficiency in
materials of different Raman gain profiles such as silica, ZBLAN and
chalcogenide glasses (As2S3 and As2Se3). It is predicted that ZBLAN glass leads
to the largest energy conversion efficiency of all four materials. The energy
conversion efficiency is a notion of utmost practical interest for the design
of wavelength converters and supercontinuum generation systems based on the
dynamics of soliton self-frequency shift.Comment: To be published in JOSA
Roadmap on chalcogenide photonics
Alloys of sulfur, selenium and tellurium, often referred to as chalcogenide semiconductors, offer a highly versatile, compositionally-controllable material platform for a variety of passive and active photonic applications. They are optically nonlinear, photoconductive materials with wide transmission windows that present various high- and low-index dielectric, low-epsilon and plasmonic properties across ultra-violet, visible and infrared frequencies, in addition to an, non-volatile, electrically/optically induced switching capability between phase states with markedly different electromagnetic properties. This roadmap collection presents an in-depth account of the critical role that chalcogenide semiconductors play within various traditional and emerging photonic technology platforms. The potential of this field going forward is demonstrated by presenting context and outlook on selected socio-economically important research streams utilizing chalcogenide semiconductors. To this end, this roadmap encompasses selected topics that range from systematic design of material properties and switching kinetics to device-level nanostructuring and integration within various photonic system architectures
