We show tuning of the resonance wavelength of silicon-on-insulator microring resonators with liquid crystal cladding. The electro-optic effect of the liquid crystal causes a decrease in effective refractive index for the TE-polarized light in the waveguides. Tuning of the liquid crystal birefringence affects primarily the longitudinal component of the electric field. We achieve a tuning range of 0.6 nm. Through simulation and experiment we perform a thorough study of this phenomenon.
我们展示了具有液晶包层的绝缘体上硅微环谐振器的谐振波长调谐。液晶的电光效应导致波导中TE偏振光的有效折射率降低。液晶双折射的调谐主要影响电场的纵向分量。我们实现了0.6纳米的调谐范围。通过模拟和实验，我们对这一现象进行了深入研究。
