Woodpile photonic crystals are amongst the preferred candidates for the next generation of photonics components. However, the photocurable resists used to produce them still lack the optical properties (high-n, non-linearity) suitable for photonics applications. A chemical bath deposition protocol has been adapted to deposit high-n/non-linear chalcogenide CdS on the surface of Ormocer woodpiles. The deposition parameters have been adjusted to obtain heterogeneous growth of CdS layers on the Ormocer surface. The layers shift the photonic band-gap and increase its amplitude by more than 15%. Software simulation confirmed that the woodpile effective refractive index underwent an excess of 30% increase.
木堆光子晶体是下一代光子学组件的首选候选材料之一。然而，用于制造它们的光固化抗蚀剂仍缺乏适用于光子学应用的光学特性（高折射率、非线性）。一种化学浴沉积方案已被调整，用于在有机陶瓷木堆表面沉积高折射率/非线性硫族化物硫化镉。已调整沉积参数以在有机陶瓷表面获得硫化镉层的异质生长。这些层使光子带隙发生偏移，并使其幅度增加超过15%。软件模拟证实，木堆有效折射率增加了超过30%。
