    Hooray! A new paper is published in Journal of Applied Physics!
    The paper is entitled Observation of nonlinear bands in near-field scanning optical microscopy of a photonic-crystal waveguide and describes our near-field microscopic experiments on photonic-crystal waveguides. We have measured additional bands not accounted for in the calculated bandstructure. These bands are highly nonlinear and are caused by a waveguide-specific near-field tip effect not previously reported, which can significantly phase-modulate the detected field.        to the article

    In the next two days I will be visiting the Annual Optics Conference (NNV AMO Lunteren) where I have a poster presentation on the Observation of non-linear bands in near-field scanning optical microscopy.

    Today I started my new position as Assistant Professor at Saxion University of Applied Sciences in Enschede, The Netherlands. I will be working there in the department of NanoBioInterfaces, so I am curious to this new field.
    Moreover, I still be working at the COPS group at the University of Twente, which leaves me in a privileged bridge position between both institutes.

    Hooray! A new paper is published in Applied Physics Letters!
    The paper is entitled Differential ultrafast all-optical switching of the resonances of a micropillar cavity and describes our experiments on micropillar cavities. We have all-optically switched the different transverse modes of the micropillar by free-carrier excitation. Our frequency- and time-resolved experiments reveal that the different pillar modes exhibit different relaxation dynamics. We explain the origin of the observation to stem from the non-uniform carrier density and its diffusion.        to the article
