2inihi 3inihi 4inihi InP epitaxial wafer substrate APD mea ʻike kukui no nā kamaʻilio fiber optic a i ʻole LiDAR

ʻO ka wehewehe pōkole:

ʻO ka substrate epitaxial InP ka mea kumu no ka hana ʻana i ka APD, maʻamau he mea semiconductor i waiho ʻia ma ka substrate e ka ʻenehana ulu epitaxial. ʻO nā mea maʻamau i hoʻohana ʻia, ʻo ia ka silicon (Si), gallium arsenide (GaAs), gallium nitride (GaN), etc., me nā waiwai photoelectric maikaʻi loa. ʻO ka APD photodetector kahi ʻano kūikawā o ka photodetector e hoʻohana ana i ka hopena photoelectric avalanche e hoʻonui i ka hōʻailona ʻike. Ke hana ʻia nā kiʻi kiʻi ma APD, hana ʻia nā pālua electron-hole. ʻO ka wikiwiki o kēia mau mea lawe ma lalo o ka hana o kahi kahua uila hiki ke alakaʻi i ka hoʻokumu ʻana o nā mea lawe hou aku, kahi "hopena avalanche", kahi e hoʻonui nui ai i ka hopena o kēia manawa.
ʻO nā wafers epitaxial i ulu ʻia e MOCvD ka mea nui o nā noi avalanche photodetection diode. Ua hoʻomākaukau ʻia ka papa absorption e nā mea U-InGaAs me ka doping hope <5E14. Hiki i ka papa hana ke hoʻohana i ka InP a i ʻole InAlAslayer. ʻO InP epitaxial substrate ka mea kumu no ka hana ʻana i ka APD, ka mea e hoʻoholo ai i ka hana o ka ʻike maka. ʻO ka photodetector APD kahi ʻano kiʻi kiʻi kiʻi kiʻi kiʻekiʻe, i hoʻohana nui ʻia i ka kamaʻilio, ʻike ʻana a me ke kiʻi kiʻi.

ʻO nā hiʻohiʻona koʻikoʻi o ka pepa epitaxial laser InP

1. ʻO nā hiʻohiʻona o ka pūnāwai: ʻO InP kahi ʻāpana haiki liʻiliʻi, kahi kūpono no ka ʻike kukui infrared hawewe lōʻihi, ʻoi aku ka nui o ka lōʻihi hawewe o 1.3μm a 1.5μm.
2. Hana maikaʻi: ʻO ke kiʻiʻoniʻoni InP epitaxial maikaʻi ka hana optical, e like me ka mana luminous a me ka hoʻokō quantum waho ma nā hawewe like ʻole. No ka laʻana, ma 480 nm, ʻo ka mana luminous a me ka hoʻokō quantum waho he 11.2% a me 98.8%, kēlā me kēia.
3. Ka hoʻoikaika ʻana o ka mea lawe: InP nanoparticles (NPs) hōʻike i kahi ʻano palaho hoʻonui pālua i ka wā ulu epitaxial. Hoʻopili ʻia ka manawa palaho wikiwiki i ka hoʻokomo ʻana o ka mea lawe i ka papa InGaAs, aʻo ka manawa palaho lohi e pili ana i ka hoʻohui hou ʻana o ka mea lawe ma InP NPs.
4. Nā hiʻohiʻona wela kiʻekiʻe: AlGaInAs/InP quantum well material he hana maikaʻi loa i ka wela kiʻekiʻe, hiki ke pale pono i ka leakage kahawai a hoʻomaikaʻi i nā ʻano wela kiʻekiʻe o ka laser.
5. Kaʻina hana: Hoʻoulu pinepine ʻia nā pepa epitaxial InP ma ka substrate e ka molecular beam epitaxy (MBE) a i ʻole ka ʻenehana metala-organic chemical vapor deposition (MOCVD) no ka hoʻokō ʻana i nā kiʻiʻoniʻoni kiʻekiʻe.
Hana kēia mau hiʻohiʻona i nā wafers epitaxial laser InP i nā noi koʻikoʻi i ke kamaʻilio fiber optical, ka hoʻoili kī nui a me ka ʻike optical mamao.

ʻO nā noi nui o nā papa epitaxial laser InP

1. Photonics: Hoʻohana nui ʻia nā lasers InP a me nā mea ʻike i nā kamaʻilio optical, nā kikowaena data, infrared imaging, biometrics, 3D sensing a me LiDAR.

2. Telecommunications: Loaʻa i nā mea InP nā noi koʻikoʻi i ka hoʻohui nui ʻana o nā lasers lōʻihi lōʻihi i hoʻokumu ʻia i ke silika, ʻoi aku hoʻi i nā kamaʻilio fiber optical.

3. Nā lasers infrared: Nā noi o InP-based quantum well lasers i ka mid-infrared band (e like me 4-38 microns), me ka ʻike kinoea, ka ʻike pahū a me ke kiʻi infrared.

4. Silicon photonics: Ma o ka ʻenehana hoʻohui heterogeneous, ua hoʻoneʻe ʻia ka laser InP i kahi substrate-based substrate e hana i kahi kahua hoʻohui optoelectronic silicon multifunctional.

5. High performance lasers: Hoʻohanaʻia nā mea InP e hana i nā lasers hana kiʻekiʻe, e like me InGaAsP-InP transistor lasers me ka nalu o 1.5 microns.

Hāʻawi ʻo XKH i nā wafers epitaxial InP maʻamau me nā ʻano hana like ʻole a me nā mānoanoa, e uhi ana i nā ʻano like ʻole e like me ka optical communications, sensors, 4G/5G base stations, etc. Ua hana ʻia nā huahana XKH me ka hoʻohana ʻana i nā lako MOCVD kiʻekiʻe e hōʻoia i ka hana kiʻekiʻe a me ka hilinaʻi. Ma keʻano o ka logistics, XKH he ākea ākea o nā punawai kumu honua, hiki ke maʻalahi i ka helu o nā kauoha, a hāʻawi i nā lawelawe waiwai e like me ka thinning, segmentation, etc. ka maikaʻi a me ka manawa hāʻawi. Ma hope o ka hōʻea ʻana, hiki i nā mea kūʻai ke loaʻa i ke kākoʻo ʻenehana piha a me ka lawelawe ma hope o ke kūʻai aku e hōʻoia i ka hoʻohana pono ʻana o ka huahana.
