最近，双光子聚合已成功用于制造高对比度的一维光子晶体。使用这种方法，红外光谱范围内的光子带隙反射率超过 90%。由于这一成功，人们正在探索对设计的修改，以实现光子带隙的额外可调性。在本文中，评估了通过双光子聚合制造的一维光子晶体，该晶体已被修改以包括机械弯曲。实验结果表明，这些结构允许机械诱导整个光子带隙的光谱偏移。这些结果支持通过双光子聚合制造的一维光子晶体用于光机械应用。
Recently, two-photon polymerization has been successfully employed to fabricate high-contrast one-dimensional photonic crystals. Using this approach, photonic bandgap reflectivities over 90% have been demonstrated in the infrared spectral range. As a result of this success, modifications to the design are being explored which allow additional tunability of the photonic bandgap. In this paper, a one-dimensional photonic crystal fabricated by two-photon polymerization which has been modified to include mechanical flexures is evaluated. Experimental findings suggest these structures allow mechanically induced spectral shifting of the entire photonic bandgap. These results support the use of one-dimensional photonic crystals fabricated by two-photon polymerization for opto-mechanical applications.
