GaAs yakakwirira-simba epitaxial wafer substrate gallium arsenide wafer simba laser wavelength 905nm yelaser kurapwa

Tsanangudzo Pfupi

GaAs laser epitaxial sheet inoreva imwe crystal yakaonda firimu zvinhu inoumbwa ne epitaxial kukura tekinoroji pane gallium arsenide (GaAs) substrate, iyo inoshandiswa kugadzira optoelectronic zvishandiso senge lasers.
GaAs 905 simba lasers uye GaAs high-power epitaxy chips ma lasers anobva pane gallium arsenide (GaAs) zvinhu uye anoshandiswa zvakanyanya mundima dzakawanda. Iyo MOCVD epitaxial wafer inonyanya kushandiswa mune yakakwirira simba laser diode. InGaAs quantum tsime rinoshandiswa seyakashanda layer. Iyo epitaxial wafer inoongororwa nePL, XRD, ECV uye dzimwe nzira dzekuyedza. MaGaAs 905 simba lasers uye GaAs epitaxy machipisi epamusoro-simba anoshandiswa zvakanyanya mukurapa, maindasitiri, tsvakiridzo yesainzi nedzimwe ndima nekuda kwehunyanzvi hwadzo hwepamusoro, kubuda kwesimba repamusoro uye kuita kwakanaka kwekupisa, uye zvine kukosha kwemusika kwakakosha uye kugona kwehunyanzvi.

Akakosha maficha eGaAs laser epitaxial sheet anosanganisira:

1.High electron mobility: Gallium arsenide ine high electron mobility, iyo inoita kuti GaAs laser epitaxial wafers ive nemashandisirwo akanaka mumagetsi e-high-frequency uye zvigadzirwa zvemagetsi zvinokurumidza.
2.Direct bandgap transition luminescence: Seyakananga bandgap zvinhu, gallium arsenide inogona kunyatso shandura simba remagetsi kuita simba rakajeka mumidziyo yeoptoelectronic, ichiita kuti ive yakanakira kugadzirwa kwema lasers.
3.Wavelength: GaAs 905 lasers inowanzoshanda pa905 nm, ichiita kuti ive yakakodzera kune zvakawanda zvinoshandiswa, kusanganisira biomedicine.
4.Kushanda kwepamusoro: nepamusoro-soro yekushandura photoelectric, inogona kunyatsoshandura simba remagetsi mumagetsi emagetsi.
5.Kubuda kwesimba repamusoro: Inogona kuwana simba guru uye inokodzera mamiriro ekushandiswa anoda chiedza chakasimba.
6.Good thermal performance: GaAs zvinhu zvine zvakanaka thermal conductivity, zvichibatsira kuderedza kupisa kwekushanda kwe laser uye kugadzirisa kugadzikana.
7.Wide tunability: Simba rinobuda rinogona kugadziriswa nekushandura dhiraivha ikozvino kuti ienderane nezvinodiwa zvakasiyana-siyana zvekushandisa.

Iwo makuru mashandisirwo eGaAs laser epitaxial mapiritsi anosanganisira:

1. Optical fiber communication: GaAs laser epitaxial sheet inogona kushandiswa kugadzira lasers mu optical fiber communication kuti iwane yakakwirira-kumhanya uye kure-kure-kure optical chiratidzo chekufambisa.

2. Zvishandiso zveindasitiri: Mumunda weindasitiri, GaAs laser epitaxial sheets inogona kushandiswa kune laser inotangira, laser yekumaka uye mamwe maapplication.

3. VCSEL: Vertical cavity surface emitting laser (VCSEL) ibasa rinokosha rekushandisa reGaAs laser epitaxial sheet, iyo inoshandiswa zvakanyanya mukukurukurirana kwemaziso, optical storage uye optical sensing.

4. Infrared uye spot field: GaAs laser epitaxial sheet inogonawo kushandiswa kugadzira infrared lasers, majenereta emagetsi nemimwe michina, ichiita basa rinokosha mukutsvaga infrared, chiedza kuratidza uye mamwe minda.

Kugadzirira kweGaAs laser epitaxial sheet kunonyanya kuenderana ne epitaxial kukura tekinoroji, kusanganisira simbi-organic kemikari vapor deposition (MOCVD), molecular beam epitaxial (MBE) nedzimwe nzira. Aya matekiniki anogona kunyatso kudzora ukobvu, kuumbwa uye chimiro chekristaro cheiyo epitaxial layer kuti iwane emhando yepamusoro GaAs laser epitaxial sheets.

XKH inopa magadzirirwo eGaAs epitaxial mashiti mune akasiyana zvimiro uye ukobvu, anovhara akasiyana siyana ekushandisa mu optical communications, VCSEL, infrared uye light spot fields. Zvigadzirwa zveXKH zvinogadzirwa nemidziyo yepamusoro yeMOCVD kuti ive nechokwadi chekuita kwepamusoro uye kuvimbika. Panyaya yezvirongwa, XKH ine huwandu hwakasiyana hwepasirese sosi nzira, iyo inogona kuchinjika kubata huwandu hwemaodha, uye inopa kukosha-yakawedzerwa masevhisi akadai sekunatsiridza uye kupatsanura. Maitiro ekutumira anobudirira anovimbisa pa-nguva yekuendesa uye kusangana nevatengi zvinodiwa zvemhando uye nguva dzekutumira. Vatengi vanogona kuwana yakazara tekinoroji rutsigiro uye mushure-yekutengesa sevhisi mushure mekusvika kuti ive nechokwadi chekuti chigadzirwa chinoiswa mukushandiswa zvakanaka.
