Nga Ahuatanga Matua
1.Mahinga Hiko me te Optical
· Electro-Optic Coefficient: ka tae te r33 ki te 30 pm/V (X-cut), 1.5x teitei ake i te LiNbO3, ka taea te whakarereketanga hiko ultra-wideband (>40 GHz bandwidth).
· Te Whakautu Ahurangi Whanui: Te awhe tuku 0.4–5.0 μm (8 mm te matotoru), me te mata absorption ultraviolet iti iho i te 280 nm, he pai mo nga lasers UV me nga taputapu ira quantum.
· Whakatau Pyroelectric Iti: dP/dT = 3.5×10⁻⁴ C/(m²·K), whakarite i te mau i roto i nga pūoko infrared pāmahana teitei.
2. Ngaaahua Ngaaariki me te Hangaia
· Te Kawenga Ngaaahu Teitei: 4.6 W/m·K (X-tapahia), whaawha ki te kiripaka, e mau ana -200–500°C te paihikara waiariki.
· Whakawhanake Whakawhanui Ngaariki: CTE = 4.1×10⁻⁶/K (25–1000°C), he hototahi ki te takai kirika hei whakaiti i te ahotea waiariki.
3. Mana Koha me te Tukatuka Tika
· Te Paipa Moroiti: <0.1 cm⁻² (8-inihi angiangi), te kiato wehenga <500 cm⁻² (kua manatokohia ma te kohi KOH).
· Kounga Mata: CMP-whakaparahia ki te Ra <0.5 nm, e tutuki ana i nga whakaritenga papatahi o te reanga-iti o EUV.
Nga tono matua
| Rohe | Nga Tauira Tono | Painga Hangarau |
| Whakawhitiwhiti Optical | 100G/400G DWDM lasers, kowaiwai photonics ranu kōwae | Ko te tuku angiangi whanui o te LiTaO3 me te iti o te mate arataki ngaru (α <0.1 dB/cm) ka taea te roha C-band. |
| 5G/6G Whakawhitiwhiti | Nga whiriwhiringa SAW (1.8–3.5 GHz), nga whiriwhiringa BAW-SMR | 42°Y-tapahi angiangi tutuki Kt²>15%, tuku iti mate whakaurunga (<1.5 dB) me te huri-atu teitei (>30 dB). |
| Nga Hangarau Quantum | Ko nga kaitirotiro whakaahua-kotahi, nga puna whakawhiti-whakararo | Ko te whakarea-kore teitei (χ(2)=40 pm/V) me te iti o te tatauranga pouri (<100 tatau/s) ka whakarei ake i te pono o te rahinga. |
| Te Whakatairanga Ahumahi | Pūoko pehanga teitei-mahana, nga huringa o naianei | Ko te whakautu piezoelectric a LiTaO3 wafer (g33>20 mV/m) me te whakamaarama teitei (>400°C) e pai ana ki nga taiao tino. |
Ratonga XKH
1. Hanga Wafer Ritenga
· Te Rahi me te Tapahi: 2–8-inihi angiangi me te tapahi X/Y/Z, 42°Y-tapahi, me nga tapahi koki ritenga (±0.01° te manawanui).
· Whakahaere Doping: Fe, Mg doping ma te tikanga Czochralski (awhe kukū 10¹⁶–10¹⁹ cm⁻³) ki te arotau i nga whakarea hiko-a-ringa me te pumau o te waiariki.
2.Nga Hangarau Tukatuka Ake
'
· Poling Waahanga (PPLT): Hangarau Maama-Tapahia mo nga angiangi LTOI, ka eke ki te ± 10 nm te tika o te waahi rohe me te huringa-waa-waa-rite (QPM).
· Whakakotahitanga Heterogene: Si-based LiTaO3 composite wafers (POI) me te mana matotoru (300–600 nm) me te kawe waiariki ki te 8.78 W/m·K mō ngā tātari SAW auau teitei.
3.Pūnaha Whakahaere Kounga
'
· Whakamatau Whakamutunga-ki-Whakamutunga: Raman spectroscopy (polytype verification), XRD (crystallinity), AFM (surface morphology), and optical uniformity testing (Δn <5×10⁻⁵).
4.Tautoko Roopu Taonga Ao
'
· Te Mahinga Whakaputa: Nga putanga o ia marama > 5,000 wafers (8-inihi: 70%), me te tuku ohorere 48-haora.
· Whatunga Logistics: He kapi i Uropi, Amerika Te Tai Tokerau, me Ahia-Kiwa ma te waka rererangi/moana me te takai i te pāmahana.
