Ibisobanuro bigufi:

LiNbO3 Ingot (Lithium Niobate Crystal Ingot) ni ibikoresho by'ifatizo mu buhanga bwa optoelectronics hamwe na tekinoroji ya kwant, izwiho kuba ifite coefficient zidasanzwe za electro-optique (γ₃₃ = 30.9 pm / V), ubwinshi bwagutse (400-5200 nm), n'ubushyuhe bwo hejuru bwa Curie (1210 ° C). Bitandukanye nibikoresho bisanzwe bishingiye kuri silikoni, ingirangingo za LiNbO3 zituma ibimenyetso byihuta byogutunganya no guhimba nini-aperture waveguide, bigatuma biba ngombwa kubitumanaho 5G / 6G, kwifotora kwa kwant, no kumva inganda. Iterambere rya vuba mu kwishyira hamwe (urugero, Si-ishingiye kuri wafers ya Si) hamwe no kugabanya inenge (urugero, Mg doping) byongereye uburyo bwakoreshwa mubidukikije bikabije, nk'ubushyuhe bwo hejuru (> 400 ° C) hamwe na sisitemu yo mu kirere ikomera.

Ibintu by'ingenzi biranga tekinike

LiNbO3 Ingot yerekana suite yumutungo uruta iyindi:

1. Imikorere ya Electro-Optic:

Coefficient yo hejuru idafite umurongo: d₃₃ = 34.4 pm / V, ituma igisekuru cya kabiri gihuza neza (SHG) hamwe na optique ya parametric oscillation (OPO) kumasoko ashobora guhinduka.

Ikwirakwizwa rya Broadband: Kwinjiza bike muburyo bugaragara (α <0.1 dB / cm kuri 1550 nm), ingenzi kuri C-band optique amplificateur no guhinduranya kwant.

2. Imashini & Ubushyuhe bukomeye:

Kwiyongera k'ubushyuhe buke: CTE = 14.4 × 10⁻⁶ / K (a-axis), byemeza guhuza na sisitemu ya silicon mumashanyarazi ya Hybrid Photonic.

Igisubizo Cyinshi cya Piezoelectric: g₃₃> 20 mV / m, nibyiza kubutaka bwa acoustic wave (SAW) muyunguruzi muri 5G mmWave sisitemu.

3. Kugenzura neza:

Ubucucike bwa Micropipe: <0.1 cm⁻² (ing-8-ingots), byemejwe hakoreshejwe syncrotron X-ray itandukanya.

Imirasire irwanya: Kugoreka ntoya munsi yumuriro w'amashanyarazi 100 kV / cm, byemewe mugupima ikirere.

Ingamba zikoreshwa

LiNbO3 Ingot itera udushya murwego rwo hejuru:

1. Amafoto ya Quantum:

Inkomoko imwe-Photon Inkomoko: Gukoresha umurongo utari munsi-guhinduka, LiNbO3 ituma ifoto ya foton ikomatanya kubyara kwa sisitemu yo gukwirakwiza (QKD).

Kwibuka kwa Quantum: Kwishyira hamwe na Er³⁺-dope fibre igera kuri 30% yububiko bwiza kuri 1530 nm, ingenzi kumurongo muremure wa kwant.

2. Sisitemu ya Optoelectronic Sisitemu:

Modulator yihuta cyane: X-yaciwe LiNbO3 igera kuri 40 GHz yumurongo hamwe na <1 dB igihombo cyo kwinjiza, irusha LiTaO3 muri 400G optique ya optique.

Kwikuba kabiri kwa Laser: Mg-Dope LiNbO3 (6% irenga) igabanya kwangirika kwifoto, ituma 1064 nm → 532 nm ihinduka muri sisitemu ya LiDAR.

3. Kumva inganda:

Umuvuduko ukabije w’ubushyuhe: Kora ubudahwema kuri 600 ° C, ukoreshe resonance ya piezoelectric kugirango ukurikirane imiyoboro ya peteroli / gaze.

Abahindura Ibiriho: Fe / Mg co-doping yongerera ibyiyumvo (0.1% FS) mubikorwa bya gride yubwenge.

Serivisi za XKH & Ibisubizo

Serivisi zacu LiNbO3 Ingot zakozwe muburyo bwo gupima no kumenya neza:

1. Ibihimbano byabigenewe:

Ingano Ihitamo: Ingano ya 3-8-ingana na X / Y / Z-gukata na 42 ° Y-gukata geometrie, ± 0.01 ° kwihanganira inguni.

Igenzura rya Doping: Fe / Mg gufatanya gukoresha uburyo bwa Czochralski (intera iri hagati ya 10¹⁶ - 10¹⁹ cm⁻³) kugirango hongerwe imbaraga zo kurwanya amafoto.
