Tlhaloso e Khutšoanyane:

Leqephe la epitaxial la laser la GaAs le bolela thepa e le 'ngoe ea filimi e tšesaane e entsoeng ke theknoloji ea kholo ea epitaxial holim'a substrate ea gallium arsenide (GaAs), e sebelisetsoang ho etsa lisebelisoa tsa optoelectronic tse kang lasers.
Li-laser tsa matla tsa GaAs 905 le li-chips tsa epitaxy tse matla a phahameng tsa GaAs ke li-laser tse thehiloeng thepa ea gallium arsenide (GaAs) 'me li sebelisoa haholo masimong a mangata. Wafer ea epitaxial ea MOCVD e sebelisoa haholo ho diode ea laser e matla a phahameng. Seliba sa quantum sa InGaAs se sebelisoa e le lera le sebetsang. Wafer ea epitaxial e hlahlojoa ke PL, XRD, ECV le mekhoa e meng ea liteko. Li-laser tsa matla tsa GaAs 905 le li-chips tsa epitaxy tse matla a phahameng tsa GaAs li sebelisoa haholo lipatlisisong tsa bongaka, tsa indasteri, tsa saense le masimong a mang ka lebaka la bokhoni ba tsona bo phahameng, tlhahiso ea matla a phahameng le ts'ebetso e ntle ea mocheso, 'me li na le boleng ba bohlokoa ba' maraka le bokhoni ba tekheniki.

Romella imeile ho rona

Likaroloana

Likarolo tsa bohlokoa tsa leqephe la laser epitaxial la GaAs li kenyelletsa:

1. Ho tsamaya ha dielektrone ka lebelo le phahameng: Gallium arsenide e na le ho tsamaya ha dielektrone ka lebelo le phahameng, e leng se etsang hore di-wafer tsa laser epitaxial tsa GaAs di be le ditshebediso tse ntle disebedisweng tse nang le maqhubu a phahameng le disebedisweng tsa elektroniki tse lebelo le phahameng.
2. Khanya ea phetoho ea lekhalo le otlolohileng la bandgap: Jwalo ka thepa ea lekhalo le otlolohileng la bandgap, gallium arsenide e ka fetola matla a motlakase ka katleho hore e be matla a leseli lisebelisoa tsa optoelectronic, e leng se etsang hore e be e loketseng tlhahiso ea lasers.
3. Bolelele ba maqhubu: Li-laser tsa GaAs 905 hangata li sebetsa ho 905 nm, e leng se etsang hore li lokele lits'ebetso tse ngata, ho kenyeletsoa le biomedicine.
4. Bokgoni bo phahameng: ka bokgoni bo phahameng ba ho fetolela motlakase ka photoelectric, e ka fetola matla a motlakase ka katleho hore e be tlhahiso ya laser.
5. Matla a phahameng a tlhahiso: E ka fihlella matla a mangata a tlhahiso mme e loketse maemo a ts'ebeliso a hlokang mohloli o matla oa leseli.
6.Ts'ebetso e ntle ea mocheso: Thepa ea GaAs e na le conductivity e ntle ea mocheso, e thusang ho fokotsa mocheso o sebetsang oa laser le ho ntlafatsa botsitso.
7. Ho kgona ho lokisa ka bophara: Matla a tlhahiso a ka fetoloa ka ho fetola hona joale ha drive ho ikamahanya le ditlhoko tse fapaneng tsa tshebediso.

Litšebeliso tse ka sehloohong tsa matlapa a GaAs laser epitaxial li kenyelletsa:

1. Puisano ea faeba ea mahlo: Leqephe la epitaxial la laser la GaAs le ka sebelisoa ho hlahisa li-laser puisanong ea faeba ea mahlo ho fihlela phetiso ea lets'oao la mahlo ka lebelo le phahameng le sebaka se selelele.

2. Ditshebediso tsa indasteri: Lefapheng la indasteri, maqephe a GaAs a laser epitaxial a ka sebediswa bakeng sa ho lekanya laser, ho tshwaya laser le ditshebediso tse ding.

3. VCSEL: Lesetara e ntšang bokaholimo ba cavity e otlolohileng (VCSEL) ke tšimo ea bohlokoa ea ts'ebeliso ea lakane ea epitaxial ea laser ea GaAs, e sebelisoang haholo puisanong ea optical, polokelong ea optical le ho lemoha optical.

4. Tšimo ea infrared le spot: Leqephe la epitaxial la laser la GaAs le ka boela la sebelisoa ho etsa li-laser tsa infrared, lijenereithara tsa spot le lisebelisoa tse ling, li bapala karolo ea bohlokoa ho fumaneng infrared, ponts'o ea leseli le masimo a mang.

Ho lokisoa ha lakane ea epitaxial ea laser ea GaAs ho itšetlehile haholo ka theknoloji ea kholo ea epitaxial, ho kenyeletsoa le ho beoa ha mouoane oa lik'hemik'hale tsa tšepe-organic (MOCVD), epitaxial ea molecular beam (MBE) le mekhoa e meng. Mekhoa ena e ka laola ka nepo botenya, sebopeho le sebopeho sa kristale sa lera la epitaxial ho fumana maqephe a epitaxial a laser a GaAs a boleng bo holimo.

XKH e fana ka mekhoa ea ho iketsetsa maqephe a GaAs epitaxial ka meaho le botenya bo fapaneng, e akaretsa mefuta e mengata ea lits'ebetso puisanong ea optical, VCSEL, infrared le masimo a mabone. Lihlahisoa tsa XKH li entsoe ka lisebelisoa tse tsoetseng pele tsa MOCVD ho netefatsa ts'ebetso e phahameng le ts'epo. Mabapi le thepa, XKH e na le mefuta e mengata ea liteishene tsa mohloli oa machaba, tse ka sebetsanang ka mokhoa o feto-fetohang le palo ea liodara, le ho fana ka lits'ebeletso tse nang le boleng bo eketsehileng joalo ka ntlafatso le karohano. Mekhoa e sebetsang ea ho fana ka thepa e netefatsa ho fana ka thepa ka nako le ho fihlela litlhoko tsa bareki bakeng sa boleng le linako tsa ho fana ka thepa. Bareki ba ka fumana tšehetso e felletseng ea tekheniki le ts'ebeletso ea kamora thekiso kamora ho fihla ho netefatsa hore sehlahisoa se sebelisoa hantle.
