文摘
- •
Liquid crystals is encapsulated in a specially designed capillary optical fiber with tubular core.
- •
Liquid crystals is driven by external electronic field to modulate the light transition through the interaction between the LCs and the tubular core.
- •
The integrated in-fiber modulator is modulation-depth-tunable.
- •
Only a trace amount of 2.71×10−2 nL of the liquid crystals can obtain a wide range of stable modulation-depth from 23% to 50%.
