GaAs laser epitaxial wafer 4 inchi 6 inchi VCSEL vertical cavity surface emission laser wavelength 940nm single junction

Kufotokozera Kwachidule:

Kapangidwe ka kasitomala Gigabit Ethernet laser arrays kuti ikhale yofanana kwambiri ma wafers a mainchesi 6 850/940nm center optical wavelength oxide limited kapena proton-implanted VCSEL digital data link communication, laser mouse electrical and optical characteristics low sensitivity to temperature. VCSEL-940 Single Junction ndi vertical cavity surface emitting laser (VCSEL) yokhala ndi emission wavelength nthawi zambiri pafupifupi 940 nanometers. Ma laser otere nthawi zambiri amakhala ndi single quantum weld ndipo amatha kupereka kuwala koyenera. Kutalika kwa kutalika kwa 940 nanometers kumapangitsa kuti ikhale mu infrared spectrum, yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana. Poyerekeza ndi mitundu ina ya ma laser, ma VCsel ali ndi mphamvu yayikulu yosinthira ma electro-optical. Phukusi la VCSEL ndi laling'ono komanso losavuta kuphatikiza. Kugwiritsa ntchito kwakukulu kwa VCSEL-940 kwapangitsa kuti ikhale ndi gawo lofunika kwambiri muukadaulo wamakono.

Mawonekedwe

Makhalidwe akuluakulu a pepala la laser epitaxial la GaAs ndi awa:

1. Kapangidwe ka malo amodzi: Laser iyi nthawi zambiri imapangidwa ndi chitsime chimodzi cha quantum, chomwe chingapereke kuwala kothandiza.
2. Kutalika kwa mafunde: Kutalika kwa mafunde kwa 940 nm kumapangitsa kuti ikhale mu infrared spectrum range, yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.
3. Kugwiritsa ntchito bwino kwambiri: Poyerekeza ndi mitundu ina ya ma laser, VCSEL ili ndi mphamvu yosinthira kuwala kwa electro-optical.
4. Kuphatikizika: Phukusi la VCSEL ndi laling'ono komanso losavuta kuliphatikiza.

5. Mphamvu yochepa yamagetsi komanso magwiridwe antchito apamwamba: Ma laser a heterostructure obisika amakhala ndi mphamvu yochepa kwambiri yamagetsi yamagetsi (monga 4mA/cm²) komanso mphamvu yayikulu yamagetsi yakunja (monga 36%), yokhala ndi mphamvu yotulutsa yoposa 15mW.
6. Kukhazikika kwa mawonekedwe a Waveguide: Laser yobisika yokhala ndi heterostructure ili ndi ubwino wa kukhazikika kwa mawonekedwe a waveguide chifukwa cha njira yake yowongolera ma waveguide yoyang'aniridwa ndi refractive index komanso m'lifupi mwake wa active strip (pafupifupi 2μm).
7. Kugwira bwino ntchito kwa photoelectric: Mwa kukonza njira yokulira ya epitaxial, kugwira bwino ntchito kwa quantum mkati ndi kugwira bwino ntchito kwa photoelectric kungapezeke kuti kuchepetse kutayika kwa mkati.
8. Kudalirika kwambiri ndi moyo: ukadaulo wapamwamba kwambiri wa kukula kwa epitaxial ukhoza kukonza mapepala a epitaxial okhala ndi mawonekedwe abwino komanso ofooka pang'ono, zomwe zimapangitsa kuti zinthu zikhale zodalirika komanso moyo ukhale wabwino.
9. Yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana: Chipepala cha epitaxial cha laser diode chochokera ku GAAS chimagwiritsidwa ntchito kwambiri polankhulana ndi ulusi wa kuwala, ntchito zamafakitale, ma infrared ndi ma photodetector ndi madera ena.

Njira zazikulu zogwiritsira ntchito pepala la laser epitaxial la GaAs ndi monga:

1. Kulankhulana kwa kuwala ndi kulumikizana kwa deta: Ma wafer a GaAs epitaxial amagwiritsidwa ntchito kwambiri pakulankhulana kwa kuwala, makamaka m'makina olumikizirana a kuwala othamanga kwambiri, popanga zida zamagetsi monga ma laser ndi zowunikira.

2. Ntchito zamafakitale: Mapepala a GaAs laser epitaxial amagwiritsidwanso ntchito kwambiri pamafakitale, monga kukonza, kuyeza ndi kuzindikira pogwiritsa ntchito laser.

3. Zipangizo zamagetsi zogwiritsidwa ntchito ndi ogula: Mu zipangizo zamagetsi zogwiritsidwa ntchito ndi ogula, ma wafer a GaAs epitaxial amagwiritsidwa ntchito popanga ma VCsels (ma laser ozungulira pamwamba), omwe amagwiritsidwa ntchito kwambiri m'mafoni ndi zida zina zamagetsi zogwiritsidwa ntchito ndi ogula.

4. Kugwiritsa ntchito Rf: Zipangizo za GaAs zili ndi ubwino waukulu m'munda wa RF ndipo zimagwiritsidwa ntchito popanga zipangizo za RF zogwira ntchito kwambiri.

5. Ma laser a quantum dot: Ma laser a quantum dot ochokera ku GAAS amagwiritsidwa ntchito kwambiri pakulankhulana, zachipatala komanso zankhondo, makamaka mu gulu lolumikizirana la 1.31µm.

6. Passive Q switch: GaAs absorber imagwiritsidwa ntchito pa ma lasers olimba opompedwa ndi diode okhala ndi passive Q switch, yomwe ndi yoyenera pa micro-machining, ranging ndi micro-surgery.

Mapulogalamuwa akuwonetsa kuthekera kwa ma GaAs laser epitaxial wafers m'mapulogalamu osiyanasiyana apamwamba.

XKH imapereka ma wafer a GaAs epitaxial okhala ndi kapangidwe ndi makulidwe osiyanasiyana opangidwa mogwirizana ndi zosowa za makasitomala, omwe amagwiritsa ntchito ntchito zosiyanasiyana monga VCSEL/HCSEL, WLAN, 4G/5G base stations, ndi zina zotero. Zogulitsa za XKH zimapangidwa pogwiritsa ntchito zida zapamwamba za MOCVD kuti zitsimikizire kuti zikugwira ntchito bwino komanso kudalirika. Ponena za kayendetsedwe ka zinthu, tili ndi njira zosiyanasiyana zopezera zinthu padziko lonse lapansi, titha kusamalira mosavuta kuchuluka kwa maoda, ndikupereka ntchito zowonjezera monga kuchepetsa, kugawa, ndi zina zotero. Njira zotumizira bwino zimatsimikizira kutumiza pa nthawi yake ndikukwaniritsa zofunikira za makasitomala kuti zikhale zabwino komanso nthawi yotumizira. Makasitomala akafika, amatha kupeza chithandizo chokwanira chaukadaulo ndi ntchito yogulitsa pambuyo pogulitsa kuti atsimikizire kuti malondawo agwiritsidwa ntchito bwino.
