Ibiranga Tekiniki by'ingenzi

LiNbO3 Ingot igaragaza imiterere myiza cyane:

1. Imikorere ya Electro-Optic:

Koefficient yo hejuru idafite umurongo ngenderwaho: d₃₃= 34.4 pm/V, ituma habaho gukora neza kwa kabiri kwa harmonic (SHG) na optique parametric oscillation (OPO) ku masoko ya infrared ashobora guhinduka.

Kohereza umuyoboro mugari: Kwinjira gake mu buryo bugaragara (α < 0.1 dB/cm kuri 1550 nm), ni ingenzi cyane kuri amplifiers za C-band optique na guhindura frequency ya quantum.

2. Ubushobozi bwo gukomera mu byuma n'ubushyuhe:

Kwaguka k'ubushyuhe buri hasi: CTE = 14.4×10⁻⁶/K (umurongo wa a), bishimangira ko bihuye na substrates za silikoni mu miyoboro ya fotoniki ivanze.

Uburyo bwo gupima amashanyarazi buhanitse: g₃₃> 20 mV/m, ni bwiza cyane ku ma filters y’umuraba w’ubuso (SAW) muri sisitemu ya 5G mmWave.

3. Kugenzura neza inenge:

Ubucucike bwa micropipe: <0.1 cm⁻² (ingots za santimetero 8), byemejwe binyuze mu gukwirakwiza X-ray kuri synchrotron.

Ubudahangarwa bw'imirasire: Guhindagurika guke kwa lattice munsi ya 100 kV/cm amashanyarazi, byemejwe mu igeragezwa ry'ikirere.

Porogaramu z'ingamba

LiNbO3 Ingot iyobora udushya mu nzego zigezweho:

1. Ifotonike ya Quantum:

Inkomoko ya Foton imwe: Ikoresheje uburyo butari bwo bwo guhindura imiterere y’amajwi, LiNbO3 ituma habaho imikorere ya photon pair ivanze mu buryo bwa quantum key distribution (QKD).

Ubwibutso bwa Quantum: Guhuza na fibres za Er³⁺bitanga ubushobozi bwo kubika 30% kuri 1530 nm, bikaba ari ingenzi cyane ku miyoboro ya quantum ikora kure.

2. Sisitemu z'ikoranabuhanga:

Modulator zihuta cyane: LiNbO3 icutse X igera ku muvuduko wa 40 GHz hamwe n'igihombo cyo gushyiramo <1 dB, irusha LiTaO3 gukora neza muri transceivers za 400G optique.

Gusubiramo inshuro ebyiri hakoreshejwe laser: LiNbO3 ifite Mg (umubare fatizo wa 6%) igabanya kwangirika kwa photorefractive, bigatuma habaho ihinduka rihamye rya 1064 nm → 532 nm muri sisitemu za LiDAR.
