Abstract / Bemerkung
Golden Vogel spirals, as deterministic aperiodic structures, support isotropic photonic band gaps and have inter-esting applications. Localized modes, such as band-edge states, are essential for tailored light-matter interaction. Here we report imaging of such modes using photoemission electron microscopy (PEEM). Tunable ultrashort light pulses excite them in golden Vogel spirals that were fabricated by focused-ion-beam (FIB) milling of an a-Si:H layer. The local near-field leads to electron emission, which is detected spatially resolved. The demonstration of FIB-textured a-Si:H as photonic material and the ability of mode imaging by PEEM offers means to spatiotemporally resolve mode dynamics and to perform nanospectroscopy.
