Hunhu Hukuru hweUnyanzvi

LiNbO3 Ingot ine zvinhu zvakawanda zvakanaka:

1. Kushanda kweElectro-Optic:

High Nonlinear Coefficient: d₃₃= 34.4 pm/V, zvichiita kuti kugadzirwa kwechipiri kwe harmonic (SHG) kushande zvakanaka uye optical parametric oscillation (OPO) kune ma infrared sources anogona kugadziriswa.

Kutumirwa kweBroadband: Kushoma kwekupinza mu spectrum inooneka (α < 0.1 dB/cm pa 1550 nm), zvakakosha kune C-band optical amplifiers uye quantum frequency conversion.

2. Kusimba kweMichina & Kupisa:

Kuwedzera Kwekupisa Kwakaderera: CTE = 14.4×10⁻⁶/K (a-axis), zvichiita kuti ienderane nesilicon substrates mu hybrid photonic circuits.

Mhinduro yePiezoelectric Yakakwira: g₃₃> 20 mV/m, yakakodzera mafirita esurface acoustic wave (SAW) mumasisitimu e5G mmWave.

3. Kudzora Zvikanganiso:

Kuwanda kweMicropipe: <0.1 cm⁻² (8-inch ingots), yakasimbiswa kuburikidza ne synchrotron X-ray diffraction.

Kuramba Kushandiswa Kwemwaranzi: Kukanganiswa kushoma kwelattice pasi pe100 kV/cm minda yemagetsi, kwakasimbiswa mukuongororwa kwemhando yemuchadenga.

Maitiro Ekushandisa

LiNbO3 Ingot inosimudzira hunyanzvi hwekugadzira zvinhu zvitsva munzvimbo dzemazuva ano:

1. Quantum Photonics:

Manyuko ePhoton Imwe Chete: Ichishandisa nonlinear down-conversion, LiNbO3 inogonesa kugadzirwa kwephoton pair yakavharika ye quantum key distribution (QKD) systems.

Memory yeQuantum: Kubatanidzwa neEr³⁺-doped fiberskunoita kuti kuchengetedza kushande ne30% pa1530 nm, zvakakosha kune network dzequantum dziri kure.

Mhedziso

LiNbO3 Ingot inoramba iri chinhu chinosarudzwa nevezvemagetsi echizvarwa chinotevera, ichisanganisa mashandiro emagetsi asingaenzaniswi nekuvimbika kweindasitiri. Kubva pa quantum computing kusvika pa 6G communications, kushandiswa kwayo kwakasiyana-siyana uye kugona kwayo kukura kunoita kuti ive chinhu chakakosha chinopa matekinoroji emangwana. Batana nesu kuti tishandise nzira dzemazuva ano dzekushandisa mishonga yekurapa, kuderedza zvikanganiso, uye mhinduro dzakasiyana dzekubatanidza dzakagadzirirwa zvaunoda.
