GaAs high-power epitaxial wafer gawo lapansi gallium arsenide wafer mphamvu laser wavelength 905nm kwa laser chithandizo

GaAs high-power epitaxial wafer substrate gallium arsenide wafer mphamvu laser wavelength 905nm kwa laser chithandizo chamankhwala Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

GaAs laser epitaxial sheet imatanthawuza filimu imodzi yopyapyala yopangidwa ndi teknoloji ya kukula kwa epitaxial pa gawo lapansi la gallium arsenide (GaAs), yomwe imagwiritsidwa ntchito popanga zipangizo za optoelectronic monga lasers.
Ma lasers amphamvu a GaAs 905 ndi ma GaAs apamwamba amphamvu epitaxy chips ndi ma lasers ozikidwa pa zida za gallium arsenide (GaAs) ndipo amagwiritsidwa ntchito kwambiri m'magawo ambiri. The MOCVD epitaxial wafer makamaka ntchito mkulu mphamvu laser diode. InGaAs quantum bwino imagwiritsidwa ntchito ngati gawo logwira ntchito. Epitaxial wafer imawunikidwa ndi PL, XRD, ECV ndi njira zina zoyesera. Ma lasers amphamvu a GaAs 905 ndi ma GaAs apamwamba a epitaxy chips amagwiritsidwa ntchito kwambiri mu zamankhwala, mafakitale, kafukufuku wasayansi ndi madera ena chifukwa chakuchita bwino kwambiri, kutulutsa mphamvu zambiri komanso magwiridwe antchito abwino amafuta, ndipo ali ndi mtengo wofunikira wamsika komanso luso laukadaulo.

Zofunikira za pepala la laser epitaxial la GaAs ndi:

1.Kuyenda kwa electron: Gallium arsenide ili ndi kayendedwe kapamwamba ka electron, zomwe zimapangitsa GaAs laser epitaxial wafers kukhala ndi ntchito zabwino pazida zothamanga kwambiri ndi zipangizo zamagetsi zothamanga kwambiri.
2.Direct bandgap transition luminescence: Monga bandgap yachindunji, gallium arsenide imatha kusintha bwino mphamvu yamagetsi kukhala mphamvu yowunikira mu zida za optoelectronic, ndikupangitsa kuti ikhale yabwino kupanga ma laser.
3.Wavelength: Ma laser a GaAs 905 nthawi zambiri amagwira ntchito pa 905 nm, kuwapanga kukhala oyenera ntchito zambiri, kuphatikiza biomedicine.
4.Kugwira ntchito kwakukulu: ndi kutembenuka kwapamwamba kwa photoelectric, kungathe kusintha bwino mphamvu zamagetsi kukhala laser.
5.Kutulutsa mphamvu kwamphamvu: Ikhoza kukwaniritsa mphamvu yamphamvu kwambiri ndipo ndi yoyenera pazochitika zogwiritsira ntchito zomwe zimafuna kuwala kwamphamvu.
6.Kugwira ntchito bwino kwamafuta: Zakuthupi za GaAs zimakhala ndi kutentha kwabwino, zomwe zimathandiza kuchepetsa kutentha kwa laser ndikuwongolera kukhazikika.
7.Wide tunability: Mphamvu yotulutsa imatha kusinthidwa mwa kusintha galimoto yamakono kuti igwirizane ndi zofunikira zosiyanasiyana.

Ntchito zazikulu za mapiritsi a GaAs laser epitaxial ndi awa:

1. Kuyankhulana kwa fiber: GaAs laser epitaxial sheet ingagwiritsidwe ntchito kupanga ma lasers mu optical fiber communication kuti akwaniritse kuthamanga kwapamwamba komanso mtunda wautali.

2. Ntchito zamafakitale: M'munda wa mafakitale, mapepala a laser epitaxial a GaAs angagwiritsidwe ntchito pamtundu wa laser, laser marking ndi ntchito zina.

3. VCSEL: Vertical cavity surface emitting laser (VCSEL) ndi gawo lofunika kwambiri la ntchito ya GaAs laser epitaxial sheet, yomwe imagwiritsidwa ntchito kwambiri poyankhulana ndi kuwala, kusungirako kuwala ndi kuwala kwa kuwala.

4. Infrared and spot field: GaAs laser epitaxial sheet ingagwiritsidwenso ntchito kupanga ma lasers a infrared, ma jenereta a malo ndi zipangizo zina, zomwe zimagwira ntchito yofunikira pakuzindikira kwa infrared, kuwonetsera kuwala ndi zina.

Kukonzekera kwa GaAs laser epitaxial sheet makamaka kumadalira luso la kukula kwa epitaxial, kuphatikizapo zitsulo-organic chemical vapor deposition (MOCVD), molecular beam epitaxial (MBE) ndi njira zina. Njirazi zimatha kuwongolera ndendende makulidwe, kapangidwe kake ndi mawonekedwe a kristalo a epitaxial wosanjikiza kuti apeze mapepala apamwamba a GaAs laser epitaxial.

XKH imapereka makonda a mapepala a epitaxial a GaAs m'mapangidwe osiyanasiyana ndi makulidwe osiyanasiyana, okhudzana ndi ntchito zosiyanasiyana mu optical communications, VCSEL, infrared and light spot fields. Zogulitsa za XKH zimapangidwa ndi zida zapamwamba za MOCVD kuti zitsimikizire kuti zikuyenda bwino komanso zodalirika. Pankhani ya mayendedwe, XKH ili ndi njira zambiri zapadziko lonse lapansi, zomwe zimatha kuthana ndi kuchuluka kwa madongosolo, ndikupereka mautumiki owonjezera monga kuwongolera ndi kugawa. Njira zoperekera bwino zimatsimikizira kutumiza pa nthawi yake ndikukwaniritsa zofunikira zamakasitomala pazabwino komanso nthawi yobweretsera. Makasitomala atha kupeza chithandizo chokwanira chaukadaulo komanso ntchito zogulitsa pambuyo pofika kuti zitsimikizire kuti malondawo akugwiritsidwa ntchito bwino.
