Tsanangudzo Pfupi

Mutengi anotsanangurwa dhizaini Gigabit Ethernet laser arrays yekukwirira kwakafanana 6-inch wafers 850/940nm centre optical wavelength oxide yakaganhurirwa kana proton-yakasimwa VCSEL yedhijitari data link kutaurirana, laser mbeva magetsi uye optical maitiro akaderera kusanzwa kune tembiricha. Iyo VCSEL-940 Single Junction is a vertical cavity surface emitting laser (VCSEL) ine emission wavelength kazhinji yakatenderedza 940 nanometers. Ma lasers akadaro anowanzo kuve ane imwechete quantum tsime uye anokwanisa kupa inoshanda mwenje emission. Iyo wavelength ye940 nanometers inoita kuti ive mune infrared spectrum, yakakodzera kune akasiyana maapplication. Kuenzaniswa nemamwe marudzi emalaser, VCsels ine yakakwirira electro-optical kutendeuka kunyatsoshanda. Iyo VCSEL package idiki uye iri nyore kubatanidza. Iko kushandiswa kwakakura kweVCSEL-940 kwaita kuti iite basa rakakosha mune tekinoroji yemazuva ano.

Iwo makuru maitiro eGaAs laser epitaxial sheet anosanganisira

1. Single-junction structure: Iyi laser inowanzo umbwa imwe chete quantum tsime, iyo inogona kupa hunobudirira chiedza emission.
2. Wavelength: Kureba kwe940 nm kunoita kuti ive mu infrared spectrum range, yakakodzera kune zvakasiyana-siyana zvekushandisa.
3. Kubudirira kwepamusoro: Kuenzaniswa nemamwe marudzi e lasers, VCSEL ine high electro-optical conversion performance.
4. Kubatana: Iyo VCSEL package idiki uye iri nyore kubatanidza.

5. Kuderera kwechikumbaridzo ikozvino uye kushanda kwakanyanya: Akavigwa heterostructure lasers anoratidza yakanyanya kuderera lasing pachikumbaridzo ikozvino density (eg 4mA/cm²) uye yakakwirira yekunze musiyano quantum kunyatsoshanda (eg 36%), ine linear kubuda simba rinopfuura 15mW.
6. Waveguide mode kugadzikana: Iyo yakavigwa heterostructure laser ine mukana wewaveguide mode kugadzikana nekuda kweiyo refractive index inotungamirwa waveguide mechanism uye nhete inoshanda strip upamhi (inenge 2μm).
7. Yakanakisa photoelectric kutendeuka kushanda zvakanaka: Nokugadzirisa epitaxial kukura kwemaitiro, yakakwirira yemukati quantum kunyatsoshanda uye photoelectric kutendeuka kushanda kunogona kuwanikwa kuderedza kurasikirwa kwemukati.
8. Kuvimbika kwepamusoro uye hupenyu: yakakwirira-yepamusoro epitaxial kukura tekinoroji inogona kugadzirira epitaxial mashizha ane chimiro chakanaka chepamusoro uye yakaderera density, kuvandudza chigadzirwa kuvimbika uye hupenyu.
9. Inokodzera kushandiswa kwakasiyana-siyana: GAAS-based laser diode epitaxial sheet inoshandiswa zvakanyanya mu optical fiber communication, kushandiswa kwemaindasitiri, infrared uye photodetectors nedzimwe ndima.

Nzira huru dzekushandisa dzeGaAs laser epitaxial sheet dzinosanganisira

1. Optical communication uye data communication: GaAs epitaxial wafers inoshandiswa zvakanyanya mumunda we optical communication, kunyanya mu-high-speed optical communication systems, yekugadzira michina ye optoelectronic yakadai se lasers uye detectors.

2. Zvishandiso zveindasitiri: GaAs laser epitaxial sheets inewo zvakakosha kushandiswa mumaindasitiri ekushandisa, akadai selaser processing, kuyerwa uye kunzwa.

3. Consumer electronics: Mumagetsi emagetsi emagetsi, maGaAs epitaxial wafers anoshandiswa kugadzira VCsels (vertical cavity surface-emitting lasers), iyo inoshandiswa zvakanyanya mumafoni uye mamwe magetsi emagetsi.

4. Rf zvikumbiro: Zvishandiso zveGaAs zvine zvakakosha mundima yeRF uye zvinoshandiswa kugadzira zvigadzirwa zvepamusoro zveRF.

5. Quantum dot lasers: GAAS-based quantum dot lasers inoshandiswa zvakanyanya mukukurukurirana, mishonga uye mauto ehondo, kunyanya mu 1.31µm optical communication band.

6. Passive Q switch: Iyo GaAs absorber inoshandiswa kune diode-pumped solid state lasers ine passive Q switch, iyo yakakodzera micro-machining, kubva uye micro-surgery.

Aya maapplication anoratidza kugona kweGaAs laser epitaxial wafers mune dzakasiyana siyana dzepamusoro-tech application.

XKH inopa maGaAs epitaxial wafers ane zvimiro zvakasiyana uye makobvu akaenderana nezvinodiwa nevatengi, anovhara zvakasiyana-siyana zvekushandisa zvakaita seVCSEL/HCSEL, WLAN, 4G/5G base stations, nezvimwe. kuvimbika. Panyaya yezvekurongeka, tine nzira dzakasiyana-siyana dzepasi rose, dzinogona kubata huwandu hwemaodha, uye nekupa masevhisi akawedzerwa akadai sekutetepa, kupatsanura, nezvimwewo. Mafambisirwo anobudirira ekutumira anovimbisa kutakura-nguva uye kusangana nezvinodiwa nevatengi kunaka uye nguva dzekutumira. Mushure mekusvika, vatengi vanogona kuwana yakazara tekinoroji rutsigiro uye mushure-yekutengesa sevhisi kuona kuti chigadzirwa chinoiswa mukushandiswa zvakanaka.
