Kufotokozera Kwachidule:

InP epitaxial substrate ndiye maziko opangira APD, nthawi zambiri chinthu cha semiconductor chomwe chimayikidwa pagawo lapansi ndi ukadaulo wa epitaxial kukula. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo silicon (Si), gallium arsenide (GaAs), gallium nitride (GaN), etc., yokhala ndi zinthu zabwino kwambiri zazithunzi. APD photodetector ndi mtundu wapadera wa photodetector womwe umagwiritsa ntchito mphamvu ya avalanche photoelectric kuti iwonjezere chizindikiro. Pakachitika ma photon pa APD, ma electron-hole pairs amapangidwa. Kuthamanga kwa zonyamulirazi pansi pa ntchito ya magetsi kungapangitse kuti pakhale zonyamulira zambiri, "avalanche effect", yomwe imakulitsa kwambiri zomwe zikuchitika panopa.
Ma Epitaxial wafers omwe amakula ndi MOCvD ndiye amayang'ana kwambiri ntchito za avalanche photodetection diode. Wosanjikiza mayamwidwe adakonzedwa ndi zinthu za U-InGaAs zokhala ndi doping yakumbuyo <5E14. Gawo logwira ntchito litha kugwiritsa ntchito InP kapena InAlAslayer. InP epitaxial substrate ndiye maziko opangira APD, omwe amatsimikizira magwiridwe antchito a optical detector. APD photodetector ndi mtundu wa high sensitivity photodetector, yomwe imagwiritsidwa ntchito kwambiri poyankhulana, kumva ndi kulingalira.

Zofunikira za InP laser epitaxial sheet zikuphatikiza

1. Mawonekedwe a kusiyana kwa bandi: InP ili ndi kusiyana kocheperako, komwe kuli koyenera kuzindikira kuwala kwa infrared kwa nthawi yayitali, makamaka mumtunda wa 1.3μm mpaka 1.5μm.
2. Mawonekedwe a kuwala: Kanema wa InP epitaxial ali ndi mawonekedwe abwino a kuwala, monga mphamvu yowala komanso mphamvu yakunja yakunja pamafunde osiyanasiyana. Mwachitsanzo, pa 480 nm, mphamvu yowala komanso kuchuluka kwakunja kwakunja ndi 11.2% ndi 98.8%, motsatana.
3. Carrier dynamics: InP nanoparticles (NPs) amasonyeza khalidwe lowonongeka kawiri pa nthawi ya kukula kwa epitaxial. Nthawi yowola mwachangu imatchedwa jekeseni wonyamula mu InGaAs wosanjikiza, pomwe nthawi yowola pang'onopang'ono ikugwirizana ndi kuphatikizikanso kwa chonyamulira mu InP NPs.
4. Kutentha kwapamwamba: AlGaInAs / InP quantum bwino zakuthupi zimakhala ndi ntchito yabwino kwambiri pa kutentha kwakukulu, zomwe zingathe kulepheretsa kutuluka kwa mtsinje ndikuwongolera kutentha kwa laser.
5. Njira yopangira: InP epitaxial sheets nthawi zambiri imakula pa gawo lapansi ndi molecular beam epitaxy (MBE) kapena teknoloji ya metal-organic chemical vapor deposition (MOCVD) kuti akwaniritse mafilimu apamwamba kwambiri.
Makhalidwewa amapangitsa ma InP laser epitaxial wafers kukhala ndi ntchito zofunika pakulumikizana kwa fiber optical, kugawa makiyi a quantum komanso kuzindikira kwakutali.

Kugwiritsa ntchito kwakukulu kwa mapiritsi a InP laser epitaxial kumaphatikizapo

1. Photonics: InP lasers ndi detectors amagwiritsidwa ntchito kwambiri mu mauthenga a kuwala, malo opangira deta, kujambula kwa infrared, biometrics, 3D sensing ndi LiDAR.

2. Kuyankhulana: Zida za InP zimakhala ndi ntchito zofunika kwambiri pakuphatikizana kwakukulu kwa ma lasers atali-wavelength opangidwa ndi silicon, makamaka mu optical fiber communications.

3. Ma lasers a infrared: Kugwiritsa ntchito ma laser a InP-based quantum well in the mid-infrared band (monga ma microns 4-38), kuphatikizapo kumva gasi, kuzindikira kuphulika ndi kujambula kwa infrared.

4. Silicon photonics: Kupyolera mu teknoloji yosakanikirana yosakanikirana, laser InP imasamutsidwa ku gawo lapansi lopangidwa ndi silicon kuti likhale ndi multifunctional silicon optoelectronic integration platform.

5.Ma lasers apamwamba: Zida za InP zimagwiritsidwa ntchito popanga ma lasers apamwamba, monga InGaAsP-InP transistor lasers okhala ndi kutalika kwa 1.5 microns.

XKH imapereka makonda a InP epitaxial wafers ndi mapangidwe osiyanasiyana ndi makulidwe, kuphimba ntchito zosiyanasiyana monga optical communications, sensors, 4G / 5G base stations, etc. Zogulitsa za XKH zimapangidwa pogwiritsa ntchito zipangizo zamakono za MOCVD kuti zitsimikizidwe kuti zikugwira ntchito komanso kudalirika. Pankhani ya zinthu, xkhh ili ndi njira zosiyanasiyana zakudziko lonse, ndikugwiritsa ntchito ndalama zambiri monga kupsinjika, gawo, zina mwanzeru zotsimikizika zitsimikiziro za nthawi yabwino komanso yobweretsera. Mukafika, makasitomala atha kupeza chithandizo chokwanira chaukadaulo komanso ntchito zogulitsa pambuyo powonetsetsa kuti malondawo akugwiritsidwa ntchito bwino.
