PZTOI（ Lead Zirconate Titanate On insulator）Wafer is a material with a super strong electro-optical effect, and its electro-optical coefficient is 6 times that of LiNbO3. At the same time, PZT has nonlinear effect, acousto-optic effect, and piezoelectric effect.
Comparison of PZT/BTO/LN/SI
| Material | Electro-optic coefficient (pm/V) | Intrinsic bandwidth (GHz) | Light transmission range (nm) | Refractive index | Operating temperature |
| PLZT | 200 | >200 | >500 | 2.4 | <600℃ |
| LN | 30 | >200 | >330 | 2.2 | |
| BTO | 1000 | 70 | >430 | 2.3 | <120℃ |
| Si | - | 50 | >1200 | 3.4 |
* All the "electro-optic coefficients" in the table are measured values in the electro-optic modulator
* The relationship between the modulator drive voltage Vπ, power consumption P and electro-optic coefficient r: Vπ ∝ 1/r, P ∝ 1/ r2
* PZT has a large light transmission range and can be used in AR/VR and visible light radar, which is impossible with silicon
