Uiga Autu
1. Eletise ma Optical Performance
· Electro-Optic Coefficient: r33 e oʻo i le 30 pm / V (X-cut), 1.5 × maualuga atu i le LiNbO3, faʻatagaina le ultra-wideband electro-optic modulation (>40 GHz bandwidth).
· Tali Fa'aaliga Lautele: Fa'asalalauina le 0.4-5.0 μm (8 mm mafiafia), fa'atasi ai ma le mata o le ultraviolet absorption e maualalo ifo i le 280 nm, lelei mo lasers UV ma masini numera numera.
· La'ititi Pyroelectric Coefficient: dP/dT = 3.5×10⁻⁴ C/(m²·K), fa'amautinoa le mautu i le maualuga o le vevela infrared sensors.
2. Meatotino vevela ma masini
· Fa'aoso maualuga: 4.6 W/m·K (X-cut), fa'afaina le quartz, fa'atumauina -200-500°C le uila vevela.
· Fa'asa'o Fa'alautele Fa'amama maualalo: CTE = 4.1×10⁻⁶/K (25-1000°C), fa'atasi ma le fa'apipi'iina o le kasa e fa'aitiitia ai le mamafa o le vevela.
3. Pulea Fa'aletonu ma Fa'atonu Fa'atonu
· Malosi'i ole paipa: <0.1 cm⁻² (8-inisi masi), ma'ema'e ta'ese <500 cm⁻² (fa'amaonia e ala i le togitogiina o le KOH).
· Tulaga Lelei: CMP-polesi i le Ra <0.5 nm, fa'afeiloa'i EUV lithography-grade mafolafola mana'oga.
Talosaga Autu
| fanua | Fa'atinoga Fa'atusa | Tulaga Fa'ainisinia |
| Feso'ota'iga Optical | 100G/400G DWDM lasers, fa'akomepi photonics hybrid modules | LiTaO3 wafer's broadcast spectral transmission and low waveguide loss (α <0.1 dB/cm) mafai ai le fa'alauteleina C-band. |
| 5G/6G Feso'ota'iga | SAW filiga (1.8–3.5 GHz), BAW-SMR filiga | 42°Y-cut wafers maua Kt² >15%, e maua ai le gau fa'aofi maualalo (<1.5 dB) ma le ta'avale maualuga (>30 dB). |
| Quantum Technologies | Fa'amatalaga tasi-photon, fa'apogai fa'alalo-liliu puna | Ole maualuga ole laina (χ(2)=40 pm/V) ma le maualalo ole faitau pogisa (<100 counts/s) fa'aleleia le fa'amaoni quantum. |
| Fa'amatalaga Fa'apisinisi | Su'esu'e fa'aoso maualuga, transformers o lo'o iai nei | Ole tali piezoelectric ole LiTaO3 wafer (g33>20 mV/m) ma le fa'apalepale maualuga o le vevela (>400°C) e fetaui ma si'osi'omaga ogaoga. |
