Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

Laser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping

Laser &Photonics Reviews, EarlyView.
A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

Tailoring Spatial Correlations With Quantum Interference

Laser &Photonics Reviews, EarlyView.
Imposing spatial structure on interfering photons fundamentally reshapes their correlations. By controlling the mutual distinguishability of two photons, we write and edit these correlations, encoding information that is invisible to conventional intensity measurements and revealed only through their joint behavior.

Spiral photonic crystal fibers

This thesis is concerned with the study of special types of photonic crystal fibers (spiral) and their optical properties. The work is carried out using simulation techniques to obtain the modal field profile and properties for the designs. The method used in solving the Maxwell’s equations is the full vectorial finite element method with the ...
