Applied Physics Letters 106 121110 2015 AbstractIn the present paper, we propose an approach based on slow Bloch mode microcavity that enables the optical trapping of small nanoparticles over a broad surface. A specific design based on a double-period photonic crystal is presented. It enables an easy coupling using a wide free-space Gaussian beam and the cavity Q factor can be tuned at will. Moreover, the microcavity mode is mainly localized within the photonic crystal holes, meaning that each hole of the microcavity behaves as efficient nanotweezers. Experimental studies have shown that 200 nm and 100 nm particles can be trapped within the microcavity, in a spatial region that corresponds to the size of one hole (200 nm wide). The experimental trap stiffness has been extracted. It shows that this approach is among the most performant ones if we take into account the size of the cavity.

Photonics west 2015, Quantum Sensing and Nanophotonic Devices  San Francisco, USA 8 février 2015 AbstractThe mid-infrared (mid-IR, wavelength range between 2 and 10 μm) is of great interest for a huge range of applications such as medical and environment sensors, security, defense and astronomy. I will give a broad overview of the different activities recently launched in INL Lyon, in close collaboration with several French and Australian institutions, under the umbrella of “Mid-IR integrated photonics” with a particular focus on novel integrated sources for the Mid-IR including hybrid III-V semiconductors on SiGe sources, thermal sources and nonlinear sources. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
