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

Tlhaloso e Khutšoanyane:

Moralo o boletsoeng ke moreki oa Gigabit Ethernet laser arrays bakeng sa liphaephe tse phahameng tsa 6-inch 850/940nm center optical wavelength oxide limited kapa proton-e kentsoeng VCSEL digital data link communication, laser mouse ea motlakase le optical litšobotsi tse tlase kutlo ho mocheso. VCSEL-940 Single Junction ke laser cavity surface emitting laser (VCSEL) e nang le leqhubu la maqhubu hangata le pota-potileng 940 nanometers. Li-lasers tse joalo hangata li na le seliba se le seng 'me li khona ho fana ka tlhahiso e sebetsang ea khanya. Bophahamo ba maqhubu a 940 nanometers bo etsa hore e be sebonong sa infrared, se loketseng lits'ebetso tse fapaneng. Ha ho bapisoa le mefuta e meng ea li-laser, li-VCsels li na le matla a holimo a ho fetola li-electro-optical. Sephutheloana sa VCSEL se batla se le nyane ebile se bonolo ho se kopanya. Tšebeliso e pharaletseng ea VCSEL-940 e entse hore e be le karolo ea bohlokoa ho theknoloji ea morao-rao.

1. Mohaho o le mong-junction: Laser ena hangata e entsoe ka seliba se le seng sa quantum, se ka fanang ka tlhahiso e sebetsang ea khanya.
2. Wavelength: The wavelength ea 940 nm e etsa hore e be ka har'a marang-rang a marang-rang a infrared, a loketseng mefuta e sa tšoaneng ea lisebelisoa.
3. Ho sebetsa ka mokhoa o phahameng: Ha ho bapisoa le mefuta e meng ea lasers, VCSEL e na le ts'ebetso e phahameng ea phetoho ea electro-optical.
4. Compactness: Sephutheloana sa VCSEL se batla se le senyenyane 'me ho bonolo ho se kopanya.

5. Boemo bo tlase ba hona joale le bo sebetsang bo phahameng: Li-laser tse patiloeng tsa heterostructure li bonts'a matla a mangata a tlase haholo (mohlala, 4mA/cm²) le katleho e phahameng ea kantle ea phapang (mohlala 36%), e nang le matla a ho hlahisa a fetang 15mW.
6. Waveguide mode botsitso: The patoa heterostructure laser e na le molemo oa waveguide mode botsitso ka lebaka la refractive index tataisoa mochine oa waveguide le moqotetsane mafolofolo strip bophara (hoo e ka bang 2μm).
7. Molemo o motle oa ho fetola photoelectric: Ka ho ntlafatsa ts'ebetso ea ho hōla ha epitaxial, ts'ebetso e phahameng ea ka hare ea quantum le katleho ea phetoho ea photoelectric e ka fumanoa ho fokotsa tahlehelo ea ka hare.
8. Ho tšepahala ho phahameng le bophelo: theknoloji ea boleng bo phahameng ba epitaxial kgolo e ka lokisetsa maqephe a epitaxial ka ponahalo e ntle ea holim'a metsi le sekoli se tlaase, ho ntlafatsa botšepehi ba sehlahisoa le bophelo.
9. E loketse mefuta e fapaneng ea likopo: Letlapa la laser diode epitaxial ea GAAS e thehiloeng ho GAAS e sebelisoa haholo puisanong ea optical fiber, lisebelisoa tsa indasteri, infrared le photodetectors le masimo a mang.

Mekhoa e ka sehloohong ea ts'ebeliso ea pampiri ea laser epitaxial ea GaAs e kenyelletsa

1. Puisano ea optical le puisano ea data: Li-wafers tsa epitaxial tsa GaAs li sebelisoa haholo tšimong ea puisano ea optical, haholo-holo lits'ebetsong tse phahameng tsa puisano tsa optical, bakeng sa ho etsa lisebelisoa tsa optoelectronic tse kang lasers le detectors.

2. Lisebelisoa tsa indasteri: Lipampiri tsa laser epitaxial tsa GaAs li boetse li na le ts'ebeliso ea bohlokoa lits'ebetsong tsa indasteri, tse kang ho sebetsana le laser, ho lekanya le ho utloa.

3. Lisebelisoa tsa elektronike tsa bareki: Ho lisebelisoa tsa elektronike tsa bareki, li-wafers tsa epitaxial tsa GaAs li sebelisetsoa ho etsa li-VCsels (li-cavity cavity surface-emitting lasers), tse sebelisoang haholo ho li-smartphone le lisebelisoa tse ling tsa elektronike tsa bareki.

4. Lisebelisoa tsa Rf: Lisebelisoa tsa GaAs li na le melemo e mengata tšimong ea RF 'me li sebelisetsoa ho etsa lisebelisoa tsa RF tse sebetsang hantle.

5. Li-lasers tsa matheba a quantum: Li-laser tsa quantum dot tse thehiloeng ho GAAS li sebelisoa haholo litabeng tsa puisano, tsa bongaka le tsa sesole, haholo-holo sehlopheng sa 1.31µm optical communication.

6. Phetoho ea Passive Q: Mokelikeli oa GaAs o sebelisoa bakeng sa lasers ea boemo bo tiileng ba diode-pumped e nang le passive Q switch, e loketseng bakeng sa micro-machining, ho fapana le ho buuoa ka micro.

Lisebelisoa tsena li bontša bokhoni ba li-wafers tsa laser epitaxial tsa GaAs ka mefuta e mengata ea lisebelisoa tsa theknoloji e phahameng.

XKH e fana ka li-wafers tsa epitaxial tsa GaAs tse nang le mehaho le botenya bo fapaneng bo lumellanang le litlhoko tsa bareki, bo koahelang mefuta e mengata ea lisebelisoa tse kang VCSEL/HCSEL, WLAN, 4G/5G base stations, joalo-joalo Lihlahisoa tsa XKH li etsoa ho sebelisoa lisebelisoa tse tsoetseng pele tsa MOCVD ho netefatsa ts'ebetso e phahameng le tsepahala. Mabapi le tsamaiso, re na le mecha e mengata e fapaneng ea mehloli ea machaba, e ka sebetsanang le palo ea litaelo ka mokhoa o bonolo, 'me ea fana ka litšebeletso tsa bohlokoa tse kang ho fokotsa, ho arola, joalo-joalo. Mekhoa e metle ea ho fana ka thepa e netefatsa hore ho tsamaisoa ka nako le ho finyella litlhoko tsa bareki boleng le linako tsa ho fana. Kamora ho fihla, bareki ba ka fumana tšehetso e felletseng ea tekheniki le ts'ebeletso ea kamora thekiso ho netefatsa hore sehlahisoa se sebelisoa hantle.
