Vertical-cavity deg-emitting laser (VCSEL) yog ib hom semiconductor laser diode nrog laser beam emission perpendicular los ntawm sab saum toj nto, tsis zoo li cov pa ntug-emitting semiconductor lasers (tseem nyob rau hauv-plane lasers) uas emit los ntawm qhov chaw tsim los ntawm cleaving. tus kheej nti tawm ntawm wafer.
Vertical-cavity surface-emitting lasers (VCSELs) muaj ntau yam zoo dua lwm hom lasers. Cov no suav nrog:
01
nto emissions, uas muaj kev yooj yim tsim nyob rau hauv addressable arrays
02
qis kub dependence ntawm lasing wavelength
03
superior kev ntseeg
04
wafer-level manufacturing txheej txheem
VCSEL technology thiab tuag qauv
Thaum txhawb nqa cov khoom lag luam tam sim no hauv VCSEL, peb txuas ntxiv tshawb xyuas VCSEL cov thev naus laus zis kom ua tau raws li cov kev xav tau ntawm kev ua lag luam thiab ua haujlwm zoo dua rau cov neeg siv khoom.
01
Integrated Optics
Cov txheej txheem photolithography yog siv los etch hauv GaAs substrate ntawm VCSEL flip nti. Tsis muaj VCSEL / optics sib dhos txheej txheem xav tau thiab txhua yam ua tiav raws li qhov tseem ceeb ntawm VCSEL Wafer Fab txheej txheem tsim khoom. Cov thev naus laus zis no yuav ua rau txo qhov muag pom kev nyab xeeb thiab cov nqi ntim khoom (tsis muaj iav diffuser lossis kev txhawb nqa) thiab nti loj (feem ntau qhov siab). Lub backside emitter yog xav tau los pab kom cov thev naus laus zis no thaum txhim kho cov cua sov dissipation thiab tsis tas yuav tsum muaj daim ntawv cog lus.
02
Addressable Array Technology - Sab saum toj-emitting
Addressable array yog lwm lub tshuab tseem ceeb uas Brandnew tsim. Qhov chaw nyob nti yuav nquag siv hauv Automotive LIDAR daim ntawv thov, tshwj xeeb tshaj yog 1D kab scanning thiab 2D ntu scanning. Lub nti chaw nyob kuj tseem yuav siv rau hauv dToF rau cov neeg siv khoom siv.
03
Long Wavelength VCSEL (>1000nm)
Brandnew tab tom pib tshawb nrhiav kev txhim kho qhov ntev wavelength VCSEL rau ntau daim ntawv thov tshwj xeeb tshaj yog rau Qab OLED.
