Fundamental understanding of photocarrier generation, transport and recombination under a steady-state photoexcitation has been an important goal of organic electronics and photonics, since these processes govern such electronic properties of organic semiconductors as, for instance, photoconductivity. Here, we discovered that photoconductivity of a highly ordered organic semiconductor rubrene e...

The 6th International Conference on Surface Plasmon Photonics (SPP6) was held in Ottawa, Canada from May 26th to 31st, 2013. This independent series of biennial conferences is widely regarded as the premier series in the field, and the 6th edition maintained the tradition of excellence. This Focus Issue collects several papers related to research presented at SPP6, and although the number of pa...

Quantum metrology is the state-of-the-art measurement technology. It uses quantum resources to enhance the sensitivity of phase estimation over that achievable by classical physics. While single parameter estimation theory has been widely investigated, much less is known about the simultaneous estimation of multiple phases, which finds key applications in imaging and sensing. In this manuscript...

We present an adjoint-based optimization for electromagnetic design. It embeds commercial Maxwell solvers within a steepest-descent inverse-design optimization algorithm. The adjoint approach calculates shape derivatives at all points in space, but requires only two "forward" simulations. Geometrical shape parameterization is by the level set method. Our adjoint design optimization is applied t...

Nanophotonics, Nanoelectronics and Nanosensor (N3) is part of International Photonics and OptoElectronics Meetings (POEM), launched by Wuhan National Laboratory for Optoelectronics (WNLO). POEM is a large-scale multi-disciplinary international conference in the field of photonics and optoelectronics. It aims to focus on the key techniques of scientific frontier and industry in the field of opto...

The generation of continuously tunable optical delays and tunable phase shifts is a key element in microwave photonics. Among the targeted applications, one can quote the filtering of microwave signals, the synchronization of optoelectronics oscillators, and the control of optically fed phased array antennas. With these applications in view, large efforts are currently done in order to develop ...
