GaAs high-power epitaxial wafer substrate gallium arsenide wafer power laser wavelength 905nm yochizira matenda a laser

GaAs yamphamvu kwambiri ya epitaxial wafer substrate gallium arsenide wafer power laser wavelength 905nm yochizira matenda a laser Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Pepala la laser epitaxial la GaAs limatanthauza filimu imodzi yopyapyala yopangidwa ndi ukadaulo wa epitaxial growth pa gallium arsenide (GaAs), yomwe imagwiritsidwa ntchito popanga zipangizo zamagetsi monga ma laser.
Ma laser amphamvu a GaAs 905 ndi ma chips amphamvu a GaAs epitaxy ndi ma laser opangidwa kuchokera ku zinthu za gallium arsenide (GaAs) ndipo amagwiritsidwa ntchito kwambiri m'magawo ambiri. Wafer wa MOCVD epitaxial amagwiritsidwa ntchito kwambiri mu diode ya laser yamphamvu kwambiri. Chitsime cha InGaAs quantum chimagwiritsidwa ntchito ngati gawo logwira ntchito. Wafer wa epitaxial amawunikidwa pogwiritsa ntchito PL, XRD, ECV ndi njira zina zoyesera. Ma laser amphamvu a GaAs 905 ndi ma chips amphamvu a epitaxy a GaAs amagwiritsidwa ntchito kwambiri m'zachipatala, mafakitale, kafukufuku wasayansi ndi madera ena chifukwa cha kugwira ntchito kwawo bwino, kutulutsa mphamvu zambiri komanso kutentha bwino, ndipo ali ndi mtengo wofunikira pamsika komanso kuthekera kwaukadaulo.

Mawonekedwe

Zinthu zazikulu za pepala la laser epitaxial la GaAs ndi izi:

1. Kuyenda kwa ma elekitironi ambiri: Gallium arsenide imakhala ndi kuyenda kwa ma elekitironi ambiri, zomwe zimapangitsa kuti ma wafer a laser epitaxial a GaAs agwiritsidwe ntchito bwino pazida zamagetsi zama frequency ambiri komanso zamagetsi zama liwiro lalikulu.
2. Kuwala kwa kusintha kwa bandgap mwachindunji: Monga chinthu cholumikizira bandgap mwachindunji, gallium arsenide imatha kusintha mphamvu zamagetsi kukhala mphamvu yowala bwino muzipangizo zamagetsi, zomwe zimapangitsa kuti ikhale yoyenera kupanga ma laser.
3. Kutalika kwa Mafunde: Ma laser a GaAs 905 nthawi zambiri amagwira ntchito pa 905 nm, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito pazinthu zambiri, kuphatikizapo biomedicine.
4. Kuchita bwino kwambiri: ndi mphamvu zambiri zosinthira kuwala kwa dzuwa, imatha kusintha mphamvu zamagetsi kukhala mphamvu ya laser.
5. Mphamvu yotulutsa mphamvu zambiri: Imatha kutulutsa mphamvu zambiri ndipo ndi yoyenera kugwiritsa ntchito zinthu zomwe zimafuna kuwala kwamphamvu.
6. Kugwira ntchito bwino kwa kutentha: Zinthu za GaAs zimakhala ndi kutentha kwabwino, zomwe zimathandiza kuchepetsa kutentha kwa laser ndikulimbitsa kukhazikika.
7. Kusinthasintha kwakukulu: Mphamvu yotulutsa imatha kusinthidwa mwa kusintha mphamvu ya drive kuti igwirizane ndi zofunikira zosiyanasiyana zogwiritsira ntchito.

Ntchito zazikulu za mapiritsi a GaAs laser epitaxial ndi izi:

1. Kulankhulana kwa ulusi wa kuwala: Pepala la laser la GaAs epitaxial lingagwiritsidwe ntchito kupanga ma laser mu kulumikizana kwa ulusi wa kuwala kuti akwaniritse kutumiza chizindikiro cha kuwala mwachangu komanso mtunda wautali.

2. Ntchito zamafakitale: M'mafakitale, mapepala a GaAs laser epitaxial angagwiritsidwe ntchito poyesa laser, kulemba laser ndi ntchito zina.

3. VCSEL: Laser yotulutsa pamwamba pa vertical cavity (VCSEL) ndi gawo lofunika kwambiri logwiritsira ntchito pepala la laser epitaxial la GaAs, lomwe limagwiritsidwa ntchito kwambiri polumikizana ndi kuwala, kusungirako kuwala, komanso kuzindikira kuwala.

4. Malo owunikira ndi malo owunikira: Lamba la GaAs la laser epitaxial lingagwiritsidwenso ntchito popanga ma laser a infrared, majenereta a malo ndi zida zina, zomwe zimagwira ntchito yofunika kwambiri pakupeza ma infrared, chiwonetsero cha kuwala ndi malo ena.

Kukonzekera kwa pepala la laser epitaxial la GaAs kumadalira kwambiri ukadaulo wa kukula kwa epitaxial, kuphatikizapo metal-organic chemical vapor deposition (MOCVD), molecular beam epitaxial (MBE) ndi njira zina. Njirazi zimatha kuwongolera bwino makulidwe, kapangidwe ndi kapangidwe ka kristalo ka epitaxial layer kuti zipeze mapepala apamwamba a laser epitaxial a GaAs.

XKH imapereka makonzedwe a mapepala a GaAs epitaxial m'mapangidwe ndi makulidwe osiyanasiyana, kuphatikiza ntchito zosiyanasiyana mu kulumikizana kwa kuwala, VCSEL, infrared ndi malo owala. Zogulitsa za XKH zimapangidwa ndi zida zapamwamba za MOCVD kuti zitsimikizire kuti zikugwira ntchito bwino komanso kudalirika. Ponena za kayendetsedwe ka zinthu, XKH ili ndi njira zambiri zoyambira padziko lonse lapansi, zomwe zimatha kuthana ndi kuchuluka kwa maoda mosavuta, ndikupereka ntchito zowonjezera monga kukonza ndi kugawa. Njira zotumizira bwino zimatsimikizira kutumiza pa nthawi yake ndikukwaniritsa zofunikira za makasitomala kuti zikhale zabwino komanso nthawi yotumizira. Makasitomala amatha kupeza chithandizo chokwanira chaukadaulo ndi ntchito yogulitsa pambuyo pofika kuti atsimikizire kuti malondawo agwiritsidwa ntchito bwino.
