Electrical and thermal modulation of porous silicon microcavities is demonstrated based on a change in the refractive index of liquid crystals infiltrated in the porous silicon matrix. Positive and negative anisotropy liquid crystals are investigated, leading to controllable tuning to both longer and shorter wavelengths. Extinction ratios greater than 10 dB have been demonstrated. Larger attenuation can be achieved by increasing the Q-factor of the microcavities.
基于渗透在多孔硅基质中的液晶折射率变化，展示了对多孔硅微腔的电学和热学调制。研究了正负各向异性液晶，实现了对较长和较短波长的可控调谐。已证明消光比大于10分贝。通过提高微腔的品质因数可以实现更大的衰减。
