Electrowetting controlled non-volatile integrated optical switch

We present the proof of concept of the first non-volatile bistable fiber optic switch combining integrated optics and electrowetting-actuated microfluidics. Design and realization of both EWOD and photonic layer are presented and successful switching of a 2×4 network is demonstrated

Determination of energy thresholds of electron excitations at semiconductor/insulator interfaces using trap-related displacement currents

© 2019 Elsevier B.V. Spectral measurements of illumination-induced displacement currents related to trapping of charge carriers optically excited in semiconductor electrodes are shown to deliver information regarding energy onsets of electron transitions at the interface. Presented examples include determination of the conduction band offset at the GaN/Al2O3 interface and determination of charge carrier excitation spectra of two-dimensional (2D)semiconductors MoS2 and WS2 at the interface with insulating SiO2.status: publishe
