Three-dimensional femtosecond laser nanolithography of crystals
Airan Rodenas, Min Gu, Giacomo Corrielli +4
Nanostructuring hard optical crystals has so far been exclusively feasible at their surface, as stress induced crack formation and propagation has rendered high precision volume pr…
Topological insulator materials for advanced optoelectronic devices
Zengji Yue, Xiaolin Wang, Min Gu
Topological insulators are quantum materials that have an insulating bulk state and a topologically protected metallic surface state with spin and momentum helical locking and a Di…
Photo-induced change of refractive index and transparency in Bi2Te3 films
Zengji Yue, Qinjun Chen, Amit Sahu +2
We report on an 800 nm femtosecond laser beam induced giant refractive index modulation and enhancement of near-infrared transparency in topological insulator material Bi2Te3 thin…
Photocurrent Enhancement of Graphene Photodetectors by Photon Tunneling of Light into Surface Plasmons
Alireza Maleki, Benjamin P. Cumming, Min Gu +3
We demonstrate that surface plasmon resonances excited by photon tunneling through an adjacent dielectric medium enhance photocurrent detected by a graphene photodetector. The devi…
Group Theory of Chiral Photonic Crystals with 4-fold Symmetry: Band Structure and S-Parameters of Eight-Fold Intergrown Gyroid Nets
Matthias Saba, Mark D. Turner, Klaus Mecke +2
The Single Gyroid, or srs, nanostructure has attracted interest as a circular-polarisation sensitive photonic material. We develop a group theoretical and scattering matrix method,…
Group Theory of Circular-Polarization Effects in Chiral Photonic Crystals with Four-Fold Rotation Axes, Applied to the Eight-Fold Intergrowth of Gyroid Nets
Matthias Saba, Mark D. Turner, Klaus Mecke +2
We use group or representation theory and scattering matrix calculations to derive analytical results for the band structure topology and the scattering parameters, applicable to a…
