- Silicon Hyperuniform Disordered Photonic Materials with a Pronounced Gap in the Shortwave Infrared
Nicolas Muller, Jakub Haberko, Catherine Marichy and Frank Scheffold
Article first published online: 9 DEC 2013 | DOI: 10.1002/adom.201300415
The mesoscale fabrication of silicon hyperuniform disordered materials with a broad and pronounced photonic gap in the shortwave infrared is reported. Due to their unique structure and their high refractive index, these fascinating materials are predicted to possess a complete photonic bandgap in the absence of any long-range order.

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
Van Duong Ta, Rui Chen and Handong Sun
Article first published online: 4 DEC 2013 | DOI: 10.1002/adom.201300433
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.
- Laser-Mediated Programmable N Doping and Simultaneous Reduction of Graphene Oxides
Li Guo, Yong-Lai Zhang, Dong-Dong Han, Hao-Bo Jiang, Dan Wang, Xian-Bin Li, Hong Xia, Jing Feng, Qi-Dai Chen and Hong-Bo Sun
Article first published online: 2 DEC 2013 | DOI: 10.1002/adom.201300401
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
Article first published online: 2 DEC 2013 | DOI: 10.1002/adom.201300299
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.
