2inch 3inch 4inch InP epitaxial wafer substrate APD isitofu sokukhanya sonxibelelwano lwefiber optic okanye iLiDAR

Inkcazelo emfutshane:

I-InP epitaxial substrate yinto esisiseko sokwenza i-APD, ngokuqhelekileyo i-semiconductor imathiriyeli efakwe kwi-substrate ngeteknoloji yokukhula kwe-epitaxial. Izinto ezisetyenziswa ngokuqhelekileyo ziquka i-silicon (Si), i-gallium arsenide (i-GaAs), i-gallium nitride (i-GaN), njl., eneempawu ezibalaseleyo ze-photoelectric. I-APD photodetector luhlobo olukhethekileyo lwe-photodetector esebenzisa i-avalanche photoelectric effect ukuphucula isignali yokufumanisa. Xa isiganeko seefotoni kwi-APD, izibini ze-electron-hole ziyenziwa. Ukukhawuleza kwaba bathwali phantsi kwesenzo sombane wombane kunokukhokelela ekubunjweni kwabathwali abaninzi, "impembelelo ye-avalanche", eyandisa kakhulu imveliso yangoku.
Ii-Epitaxial wafers ezikhuliswe yi-MOCvD zezona kugxilwe kuzo kwi-avalanche photodetection diode applications. Uluhlu lwe-absorption lulungiswe yi-U-InGaAs impahla kunye ne-doping yangasemva <5E14. Umaleko osebenzayo unokusebenzisa i-InP okanye i-InAlAslayer. I-InP epitaxial substrate yinto esisiseko yokuvelisa i-APD, emisela ukusebenza kwe-optical detector. I-APD i-photodetector luhlobo lwe-photodetector ephezulu ye-sensitivity, esetyenziswa ngokubanzi kwiinkalo zonxibelelwano, imvakalelo kunye nemifanekiso.

Iimpawu eziphambili ze-InP laser epitaxial sheet zibandakanya

1. Iimpawu ze-Gap ye-Band: I-InP ine-gap emxinwa yebhendi, efanelekileyo yokukhangela ukukhanya kwe-infrared ye-long-wave, ngokukodwa kwi-wavelength range ye-1.3μm ukuya kwi-1.5μm.
2. Ukusebenza kwe-Optical: Ifilimu ye-InP epitaxial inokusebenza kakuhle kwe-optical, njengamandla akhanyayo kunye nokusebenza kakuhle kwe-quantum yangaphandle kumaza ahlukeneyo. Ngokomzekelo, kwi-480 nm, amandla akhanyayo kunye nokusebenza kakuhle kwe-quantum yangaphandle yi-11.2% kunye ne-98.8%, ngokulandelanayo.
3. I-Carrier dynamics: I-InP nanoparticles (NPs) ibonisa ukuziphatha okubi ngokuphindwe kabini ngexesha lokukhula kwe-epitaxial. Ixesha lokubola ngokukhawuleza libangelwa inaliti ye-carrier carrier in the InGaAs layer, ngelixa ixesha lokubola elicothayo lihambelana nokuhlanganiswa kwe-carrier kwi-InP NPs.
4. Iimpawu eziphezulu zeqondo lokushisa: I-AlGaInAs / InP quantum kakuhle impahla inokusebenza kakuhle kwiqondo lokushisa eliphezulu, elinokuthintela ngokufanelekileyo ukuvuza komsinga kunye nokuphucula iimpawu zokushisa eziphezulu ze-laser.
5. Inkqubo yokuvelisa: I-InP epitaxial sheets idla ngokukhuliswa kwi-substrate nge-molecular beam epitaxy (MBE) okanye iteknoloji ye-metal-organic chemical vapor deposition (MOCVD) ukufikelela kwiifilimu eziphezulu.
Ezi mpawu zenza i-InP laser epitaxial wafers zinezicelo ezibalulekileyo kunxibelelwano lwefiber optical, ukuhanjiswa kweqhosha le-quantum kunye nokubonwa okude.

Izicelo eziphambili ze-InP laser epitaxial tablets zibandakanya
