Bistability and boundary crisis in a semiconductor laser with phase-conjugate feedback [PDF]
, 2002 We present a detailed study of a route to chaos via quasiperiodicity on a torus in a semiconductor laser with phase-conjugate feedback. Highlighting the use of new tools that go far beyond mere simulation, we compute bifurcation diagrams and unstable ...

Advanced Functional Materials, EarlyView.In situ Auger Electron Spectroscopy resolves oxidation states with high fidelity during the pulsed laser deposition of multivalent perovskite manganate and vanadate heterostructures. The chemical‐state signature is carried by the valence‐electron population of the transition‐metal cation, read out through the relative intensities of Auger fine ...

Mode structure of a semiconductor laser with feedback from two external filters [PDF]
, 2008 We study a semiconductor laser subject to filtered optical feedback from two separate filters. This work is motivated by an application where two fiber gratings are used to stabilize the output of a laser source.

Advanced Functional Materials, EarlyView.Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance
