- Second Harmonic Generation Circular Dichroism from Self-Ordered Hybrid Plasmonic–Photonic Nanosurfaces
Alessandro Belardini, Alessio Benedetti, Marco Centini, Grigore Leahu, Francesco Mura, Simona Sennato, Concita Sibilia, Valentina Robbiano, Maria Caterina Giordano, Christian Martella, Davide Comoretto and Francesco Buatier de Mongeot

Hybrid structures composed by self-ordered dielectric nanospheres and partially covered by gold nanocrescents, produce efficient second harmonic generation signals due to the cooperative effect of localized plasmon excitation and 2D Bragg gratings. Asymmetries in the geometric shape of the gold nanocrescents induce a circularly polarized optical response.
- Coupled Polymer Microfiber Lasers for Single Mode Operation and Enhanced Refractive Index Sensing

Single mode lasing operation is obtained from coupled whispering gallery mode polymer fiber lasers via the Vernier effect. This coupled structure offers a significant improvement in sensitivity (∼400 nm/refractive index unit) for refractive index sensing compared to a single cavity. These findings imply that polymer fibers are promising candidates for micro/nano-integrated photonic devices because of their mechanical flexibility and cost-effectiveness.

Programmable N-doping and simultaneous reduction of graphine oxide (GO) by femtosecond laser direct writing in NH3 atmosphere is presented. The unique laser-mediated programmable doping permits complex micropatterns of N-doped graphene, and thus holds great promise for the fabrication and integration of graphene-based devices. N-type transistor behavior is observed in the post-fabricated field-effect transistors.
- Random Lasing with a High Quality Factor over the Whole Visible Range Based on Cascade Energy Transfer
Xiaoyu Shi, Yanrong Wang, Zhaona Wang, Sujun Wei, Yanyan Sun, Dahe Liu, Jing Zhou, Yongyi Zhang and Jinwei Shi

Low threshold coherent random lasing with a high quality factor (∼13 000) over the whole visible range is experimentally observed using gold–silver bimetallic porous nanowires with abundant nanogaps as the scatterers. Multi gain media can provide broad tunability of the emission wavelength when the system is pumped by single-wavelength laser pulses.
- Fully Flexible GaN Light-Emitting Diodes through Nanovoid-Mediated Transfer

Fully flexible GaN-LEDs yielding bright green or blue light are demonstrated. The LED structure, consisting of hard GaN light-emitting arrays embedded in a soft polymer matrix, is advantageous for high flexibility. This is enabled by accurately reducing the adhesion strength of the LT-GaN/Ti hetero-interface and transferring the stack arrays into ultrathin, flexible substrates.
