Nanophotonics, Volume 15, Issue 11, 13 June 2026.Backward optical parametric oscillation is realized in a submicron‐poled thin‐film lithium niobate microring. By engineering the quasi‐phase‐matching condition, both type‐0 and type‐I degenerate oscillation emerge in the same device and are selectively accessed through temperature tuning, providing a versatile on‐chip platform for polarization‐diverse ...

Cascaded multiparameter quantum metrology
Physical Review AWe present an innovative, platform-independent concept for multiparameter sensing where the measurable parameters are in series, or cascaded, enabling measurements as a function of position. With temporally resolved detection, we show that squeezing can give a quantum enhancement in sensitivity over that of classical states by a factor of $e^{2r ...

Control and measurement of ultrafast pulses for pump/probe-based metrology
, 2008 In this thesis the control of ultrafast (10⁻¹³ s) optical pulses used for metrological applications has been investigated. Two different measurement set-ups have been considered, both based around the `pump-probe' technique, where an optical pulse is ...

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics
Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.
