2'īniha 3'īniha 4'īniha InP epitaxial wafer substrate APD light detector no nā kamaʻilio fiber optic a i ʻole LiDAR Kiʻi i hōʻike ʻia

Wehewehe Pōkole:

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

Nā hiʻohiʻona

ʻO nā hiʻohiʻona koʻikoʻi o ka pepa epitaxial laser InP e komo pū ana

1. Nā ʻano o ka hakahaka hui: He hakahaka hui haiki ko InP, kūpono ia no ka ʻike ʻana i ke kukui infrared nalu lōʻihi, ʻoi aku hoʻi ma ka pae nalu o 1.3μm a i 1.5μm.
2. Hana Optical: Loaʻa i ka ʻili epitaxial InP ka hana optical maikaʻi, e like me ka mana luminous a me ka pono quantum waho ma nā nalu like ʻole. No ka laʻana, ma 480 nm, ʻo ka mana luminous a me ka pono quantum waho he 11.2% a me 98.8%, kēlā me kēia.
3. Nā dinamika mea lawe: Hōʻike nā nanoparticles InP (NPs) i kahi ʻano palaho exponential pālua i ka wā o ka ulu ʻana o ka epitaxial. Ua pili ka manawa palaho wikiwiki i ka hoʻokomo ʻana o ka mea lawe i loko o ka papa InGaAs, ʻoiai ʻo ka manawa palaho lohi e pili ana i ka hui hou ʻana o ka mea lawe ma InP NPs.
4. Nā ʻano wela kiʻekiʻe: Loaʻa i ka mea lua quantum AlGaInAs/InP ka hana maikaʻi loa ma ke ana wela kiʻekiʻe, hiki ke pale pono i ka liki ʻana o ke kahawai a hoʻomaikaʻi i nā ʻano wela kiʻekiʻe o ka laser.
5. Ke kaʻina hana: Hoʻoulu pinepine ʻia nā pepa epitaxial InP ma luna o ka substrate e ka molecular beam epitaxy (MBE) a i ʻole ka ʻenehana metal-organic chemical vapor deposition (MOCVD) e hoʻokō i nā kiʻiʻoniʻoni kiʻekiʻe.
ʻO kēia mau ʻano e hoʻolilo i nā wafers epitaxial laser InP i nā noi koʻikoʻi i ke kamaʻilio fiber optical, ka hoʻokaʻawale kī quantum a me ka ʻike optical mamao.

ʻO nā noi nui o nā papa epitaxial laser InP e komo pū ana

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

2. Kelekamaʻilio: He mau noi koʻikoʻi nā mea InP i ka hoʻohui nui ʻana o nā lasers lōʻihi-nalu e pili ana i ka silicon, ʻoi aku hoʻi i nā kamaʻilio fiber optical.

3. Nā lasers infrared: Nā noi o nā lasers lua quantum i hoʻokumu ʻia ma InP i ka hui mid-infrared (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, hoʻoili ʻia ka laser InP i kahi substrate e pili ana i ka silicon e hana i kahi kahua hoʻohui optoelectronic silicon multifunctional.

5. Nā lasers hana kiʻekiʻe: Hoʻohana ʻia nā mea InP e hana i nā lasers hana kiʻekiʻe, e like me nā lasers transistor InGaAsP-InP me ka nalu o 1.5 microns.

Hāʻawi ʻo XKH i nā wafers epitaxial InP i hana kūikawā ʻia me nā ʻano like ʻole a me nā mānoanoa, e uhi ana i nā ʻano hana like ʻole e like me ke kamaʻilio optical, nā sensor, nā kikowaena kumu 4G/5G, a pēlā aku. Hana ʻia nā huahana a XKH me ka hoʻohana ʻana i nā lako MOCVD holomua e hōʻoia i ka hana kiʻekiʻe a me ka hilinaʻi. Ma ke ʻano o ka logistics, loaʻa iā XKH kahi ākea o nā kahawai kumu honua, hiki ke lawelawe maʻalahi i ka nui o nā kauoha, a hāʻawi i nā lawelawe waiwai i hoʻohui ʻia e like me ka lahilahi, ka māhele ʻana, a pēlā aku. Hōʻoia nā kaʻina hana hoʻouna kūpono i ka lawe ʻana i ka manawa kūpono a hoʻokō i nā koi o ka mea kūʻai aku no ka maikaʻi a me nā manawa hoʻouna. Ma hope o ka hōʻea ʻana, hiki i nā mea kūʻai ke loaʻa ke kākoʻo loea piha a me ka lawelawe ma hope o ke kūʻai aku e hōʻoia i ka hoʻohana pono ʻia ʻana o ka huahana.
