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

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

Tlhaloso e Khutšoanyane:

Moralo o kgethilweng ke moreki Gigabit Ethernet laser arrays bakeng sa ho lekana ho hoholo Li-wafer tsa lisenthimithara tse 6 850/940nm center optical wavelength oxide limited kapa proton-implanted VCSEL digital data link puisano, laser mouse electrical le optical characteristics low sensitivity to the temperature. VCSEL-940 Single Junction ke vertical cavity surface emitting laser (VCSEL) e nang le wavelength emission hangata e ka bang 940 nanometers. Hangata li-laser tse joalo li na le seliba se le seng sa quantum mme li khona ho fana ka khanya e ntshang e sebetsang hantle. Wavelength ea 940 nanometers e etsa hore e be ka har'a infrared spectrum, e loketseng mefuta e fapaneng ea lits'ebetso. Ha e bapisoa le mefuta e meng ea li-laser, li-VCsel li na le bokhoni bo phahameng ba phetoho ea electro-optical. Sephutheloana sa VCSEL se senyenyane haholo 'me se bonolo ho se kopanya. Tšebeliso e pharaletseng ea VCSEL-940 e entse hore e bapale karolo ea bohlokoa theknolojing ea sejoale-joale.

Litšobotsi tsa mantlha tsa leqephe la laser epitaxial la GaAs li kenyelletsa

1. Sebopeho sa kgokelo e le nngwe: Lesetara ena hangata e entswe ka seliba se le seng sa quantum, se ka fanang ka kgaso e sebetsang hantle ya lesedi.
2. Bolelele ba maqhubu: Bolelele ba maqhubu ba 940 nm bo etsa hore e be sebakeng sa mahlaseli a infrared, e loketseng mefuta e fapaneng ea lits'ebetso.
3. Bokgoni bo phahameng: Ha ho bapisoa le mefuta e meng ea laser, VCSEL e na le bokhoni bo phahameng ba phetoho ea electro-optical.
4. Bophara: Sephutheloana sa VCSEL se senyenyane haholo 'me se bonolo ho se kopanya.

5. Moeli o tlase le bokgoni bo phahameng: Li-laser tsa heterostructure tse patiloeng li bonts'a bongata bo tlase haholo ba moeli o tlase (mohlala, 4mA/cm²) le bokgoni bo phahameng ba phapang ya kantle ba quantum (mohlala, 36%), ka matla a tlhahiso a mola a fetang 15mW.
6. Botsitso ba mokhoa oa Waveguide: Laser ea heterostructure e patiloeng e na le molemo oa botsitso ba mokhoa oa waveguide ka lebaka la mokhoa oa eona oa refractive index guided waveguide le bophara bo bonyenyane ba active strip (hoo e ka bang 2μm).
7. Bokgoni bo botle ba ho fetolela motlakase ka photoelectric: Ka ho ntlafatsa ts'ebetso ea kholo ea epitaxial, bokhoni bo phahameng ba quantum ba ka hare le bokhoni ba ho fetolela motlakase ka photoelectric bo ka fumanoa ho fokotsa tahlehelo ea ka hare.
8. Botšepehi bo phahameng le bophelo: Theknoloji ea kholo ea epitaxial ea boleng bo holimo e ka lokisa maqephe a epitaxial ka ponahalo e ntle ea bokaholimo le botenya bo tlase ba sekoli, e ntlafatsang botšepehi le bophelo ba sehlahisoa.
9. E loketse mefuta e fapaneng ya dikopo: Leqephe la epitaxial la laser diode le thehilweng ho GAAS le sebediswa haholo puisanong ya optical fiber, dikopo tsa indasteri, di-infrared le di-photodetector le masimong a mang.

Mekhoa e meholo ea ts'ebeliso ea lakane ea laser ea GaAs epitaxial e kenyelletsa

1. Puisano ya mahlo le puisano ya data: Di-wafer tsa GaAs epitaxial di sebediswa haholo lefapheng la puisano ya mahlo, haholoholo ditsamaisong tsa puisano ya mahlo tse potlakileng, bakeng sa ho etsa disebediswa tsa optoelectronic tse kang di-laser le di-detector.

2. Ditshebediso tsa indasteri: Maqephe a GaAs a laser epitaxial le ona a na le ditshebediso tsa bohlokwa ditshebedisong tsa indasteri, tse kang ho sebetsana le laser, ho lekanya le ho lemoha.

3. Lisebelisoa tsa elektronike tsa bareki: Lisebelisoa tsa elektronike tsa bareki, li-wafer tsa GaAs epitaxial li sebelisoa ho etsa li-VCsels (li-laser tse ntšang bokaholimo bo otlolohileng), tse sebelisoang haholo li-smartphone le lisebelisoa tse ling tsa elektronike tsa bareki.

4. Ditshebediso tsa Rf: Disebediswa tsa GaAs di na le melemo e meholo lefapheng la RF mme di sebedisetswa ho etsa disebediswa tsa RF tse sebetsang hantle.

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

6. Phetoho ea Q e sa sebetseng: Sesebelisoa sa ho monya matla sa GaAs se sebelisoa bakeng sa li-laser tse tiileng tsa state tse pompetsoeng ka diode tse nang le phetoho ea Q e sa sebetseng, e loketseng ho etsoa ka mochini o monyenyane, ho range le opereishene e nyane.

Lisebelisoa tsena li bontša bokhoni ba li-wafer tsa laser epitaxial tsa GaAs lits'ebetsong tse fapaneng tsa theknoloji e phahameng.

XKH e fana ka li-wafer tsa epitaxial tsa GaAs tse nang le meaho le botenya bo fapaneng bo etselitsoeng litlhoko tsa bareki, tse akaretsang mefuta e mengata ea lits'ebetso tse kang liteishene tsa motheo tsa VCSEL/HCSEL, WLAN, 4G/5G, jj. Lihlahisoa tsa XKH li etsoa ka lisebelisoa tse tsoetseng pele tsa MOCVD ho netefatsa ts'ebetso e phahameng le ts'epo. Mabapi le thepa, re na le mefuta e mengata ea likanale tsa mohloli oa machabeng, re ka sebetsana ka mokhoa o feto-fetohang le palo ea liodara, 'me ra fana ka lits'ebeletso tse nang le boleng bo eketsehileng joalo ka ho fokotsa, ho arola, jj. Mekhoa e sebetsang ea ho tlisa e netefatsa ho tlisa ka nako le ho fihlela litlhoko tsa bareki bakeng sa boleng le linako tsa ho tlisa. 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.
