802. Femtosecond-Laser Engineering of Glasses and Optical Fibres for High-Temperature Sensing

Matthieu Lancry (Institut de Chimie Moléculaire et des Matériaux d’Orsay (ICMMO), Université Paris-Saclay, CNRS, Orsay, France)

Invited talk

Optical fibres are attractive sensing platforms for harsh environments, but their ultimate operating temperature is set by the stability of both the glass and the laser-written structure. Femtosecond laser direct writing offers a unique route to locally engineer the refractive index and microstructure of optical glasses and fibres, enabling compact photonic devices and fibre sensors for harsh...

639. Gradient Descent Based Computer Generated Holography for High-Fidelity Wavefront Shaping Through Multimode Fibres

Deterministic control of light propagation through complex scattering media has enabled applications including optical communications, metrology, nonlinear optics, and, most notably, multimode fibre microscopy and imaging. Central to these applications is the generation of high-fidelity optical fields at the distal facet of the fibre using wavefront shaping elements such as liquid crystal...

521. Laser requirements for direct-drive inertial fusion energy

Inertial fusion energy (IFE) seeks to generate power through the repeated thermonuclear burn of small deuterium–tritium (DT) targets compressed and heated by intense, pulsed drivers. In laser-driven IFE, nanosecond pulses delivering megajoule-scale energy must ultimately operate at several shots per second with high wall-plug efficiency, precise pulse shaping, broad spectral bandwidth,...

315. Joint gas-line sensing and resilience in optical communications

Spectroscopy of gasses is a key detection technique for identifying both the type and concentration of gas. Gas absorption lines are typically on the order of ~1 GHz (8 pm) wide, and so detecting these reliably requires precision optical instrumentation. Recent progress in hollow-core optical fibers (HCFs), which present the lowest-loss waveguides for light propagation at attenuations below...

503. All-Optical Bandgap Engineering in 2D Transition Metal Dichalcogenides

Dr Sebastian Klimmer (ARC Centre of Excellence for Transformative Meta-Optical Systems, Department of Electronic Materials Engineering, Research School of Physics, The Australian National University, Canberra, ACT, 2601, Australia; Institute of Solid State Physics, Friedrich Schiller University Jena, 07743 Jena, Germany)

In contrast to conventional semiconductors, two-dimensional transition metal dichalcogenide (TMD) monolayers allow both permanent as well as tunable control of their band structure. For instance, alloying or inducing strain during growth [1,2] can permanently alter their direct, energy-degenerate band gaps at the ±K valleys of the Brillouin zone. While this approach leads to substantial shifts...
