Multifunctionality in Silicon Photonics Through Temperature‐Driven Inverse Design
Laser &Photonics Reviews, EarlyView.Temperature‐conditioned inverse design embeds thermo‐optic reconfigurability directly into compact silicon photonic devices. By co‐optimizing a single geometry at 300 K (T1) and 520 K (T2), the same structure supports distinct optical functions, enabling experimentally verified switching and mode conversion without resonant architectures or additional ...

Laser nanofabrication inside silicon with spatial beam modulation and anisotropic seeding
Nature CommunicationsNanofabrication in silicon, arguably the most important material for modern technology, has been limited exclusively to its surface. Existing lithography methods cannot penetrate the wafer surface without altering it, whereas emerging laser-based ...

Photonic nanovoids for tailored optoelectronic response in silicon solar cells
Responsive Materials, EarlyView.Optoelectronic workflow followed by experimental validation, demonstrating state‐of‐the‐art efficiency gains. Abstract As crystalline silicon (c‐Si) solar cells become thinner to reduce cost and weight, the optical design principles that govern light trapping (LT) must evolve.

Engineering and Tuning of High Quality Hexagonal Boron Nitride Nanophotonic Resonators
Small, EarlyView.The manuscript explores nanofabrication protocols for photonic crystal cavities and microdisk resonators from hexagonal boron nitride. High Q cavities are fabricated and their resonances are controllably tuned. The work is important for future realization of quantum technologies with hexagonal boron nitride.

Small, EarlyView.This work presents a bottom‐up strategy for forming meta‐structures built from DNA‐assembled nanoparticle superlattices, establishing a versatile platform for multiscale photonic materials design. Confinement stabilizes non‐equilibrium crystal habits and enables geometry and mode control independent of lattice symmetry.
