Txawm hais tias nws yog nyob rau hauv sensors rau kev tsav tsheb tsis muaj zog lossis kev saib xyuas tus neeg tsav tsheb, hauv smartphones lossis hauv cov ntaub ntawv xa mus - laser diodes los ntawm TRUMPF Photonic Cheebtsam yog siv rau hauv ntau cov ntawv thov high-tech rau cov neeg siv khoom lag luam thiab hauv kev lag luam. Lawv muab cov txiaj ntsig ntawm kev ua tau zoo tshaj plaws ntawm cov ntaub ntawv xa mus nrog kev sib piv qis zog tawm tswv yim. Nyob rau hauv cov ntaub ntawv ntawm VCSEL ( ntsug-kab noj hniav nto-emitting laser) laser diodes, lub teeb yog emitted perpendicular mus rau lub dav hlau ntawm lub semiconductor nti; Qhov no yog qhov txawv ntawm ntug-emitting laser diodes, qhov twg lub teeb tawm ntawm ib lossis ob lub npoo ntawm cov nti.
VCSEL portfolio yog tus cwj pwm los ntawm kev ua haujlwm thoob ntiaj teb hauv ntau yam kev siv sensor. Cov khoom yog siv, piv txwv li, raws li ib tug pulse qhov chaw rau lub sij hawm-ntawm kev siv davhlau ya nyob twg, raws li lub teeb qhov chaw nyob rau hauv optical encoders, los yog raws li siv lasers nyob rau hauv spectrometers. Cov khoom tsim tshiab tsim kom yooj yim rau cov tswv yim tsis tshua muaj zog, kev hloov pauv sai heev, cov kab teeb pom kev zoo tshaj plaws, kev tswj hwm polarization, lub teeb pom kev zoo nrog ib qho nqaim heev thiab cov nyhuv qis. Ntau yam kev xaiv ntim kuj ua rau cov khoom sib xyaw ua ke yooj yim dua thiab ua kom muaj cov yam ntxwv ntxiv.
Ib hom VCSEL
Ib hom VCSELs zoo kawg nkaus rau kev siv hauv ntau cov ntawv thov kev lag luam vim lawv Gaussian-shaped beam profile, lawv cov tswv yim tsis muaj zog, thiab lawv cov kev ntseeg tau zoo.
Multimode VCSEL
Multimode VCSELs yog qhov chaw teeb pom kev zoo rau cov neeg siv khoom siv mobile thiab tuaj yeem siv tau zoo hauv cov khoom siv sib xyaw ua ke vim lawv qhov loj me. 940 nm yog tus qauv wavelength rau multimode VCSEL, txawm li cas los xij, lwm qhov wavelengths kuj muaj.
