Generalized Heterodyne Interferometry in Kerr Materials

open access: yesAdvanced Photonics Research, EarlyView.
Interferometry, combined with heterodyne detection, enables simultaneous measurement of light amplitude and phase. This work applies these methods to study nonlinear phase shifts from the optical Kerr effect during laser pulse propagation. Results show the nonlinear index is straightforward to retrieve at low phases, but at higher powers, pulse shape ...

Nonvolatile and Low‐Loss Reconfigurable Optical Switches Using Sb2S3 Phase Change Material

open access: yesAdvanced Photonics Research, EarlyView.
Sb2S3‐assisted hybrid plasmonic waveguide‐based reconfigurable, nonvolatile 1 × 2 switch using an asymmetric directional coupler is presented. Its dual‐polarization functionality ensures its broader applicability and flexibility in integrated photonic systems where polarization diversity is often required.
