Photonic Crystals Fabricated by Two-Photon Polymerization with Mechanical Defects

One-dimensional photonic crystals have been used in sensing applications for decades, due to their ability induce highly reflective bandgaps. In this study, one-dimensional with alternating low- and high-density layers were fabricated from a single photosensitive polymer (IP-Dip) by two-photon polymerization. The modified include central defect layer different elastic properties compared the surrounding layers, first time. It was observed that mode resonance can be controlled compressive force. Very good agreement found between experimentally measured spectra model data. mechanical of flexure design calculated. calculated spring constant is similar magnitude those reported microsprings on scale using results study demonstrate successful control polymerization stimuli, Such structure could fields, such as micro-robotics, micro-opto–electro–mechanical systems (MOEMSs), where optical fluctuations desired.
