4. Cov xwm txheej ntawm daim ntawv thov ntawm cov lasers semiconductor uas muaj ntug-emission
Vim nws qhov dav wavelength ntau yam thiab lub zog siab, ntug-emitting semiconductor lasers tau ua tiav siv rau ntau qhov chaw xws li tsheb, kev sib txuas lus kho qhov muag thiablaserkev kho mob. Raws li Yole Developpement, ib lub koom haum tshawb fawb kev lag luam thoob ntiaj teb uas muaj npe nrov, kev lag luam laser ntug-rau-emit yuav loj hlob mus txog $ 7.4 billion hauv xyoo 2027, nrog rau kev loj hlob txhua xyoo ntawm 13%. Kev loj hlob no yuav txuas ntxiv mus los ntawm kev sib txuas lus optical, xws li optical modules, amplifiers, thiab 3D sensing applications rau kev sib txuas lus cov ntaub ntawv thiab kev sib txuas lus. Rau cov kev xav tau ntawm daim ntawv thov sib txawv, cov qauv tsim qauv EEL sib txawv tau tsim hauv kev lag luam, suav nrog: Fabripero (FP) semiconductor lasers, Distributed Bragg Reflector (DBR) semiconductor lasers, external cavity laser (ECL) semiconductor lasers, distributed feedback semiconductor lasers (DFB laser), quantum cascade semiconductor lasers (QCL), thiab wide area laser diodes (BALD).

Nrog rau qhov kev thov nce ntxiv rau kev sib txuas lus optical, 3D sensing daim ntawv thov thiab lwm yam teb, qhov kev thov rau semiconductor lasers kuj nce ntxiv. Tsis tas li ntawd, edge-emitting semiconductor lasers thiab vertical-cavity surface-emitting semiconductor lasers kuj ua lub luag haujlwm hauv kev ua kom tiav qhov tsis txaus ntawm ib leeg hauv cov ntawv thov tshiab, xws li:
(1) Hauv kev sib txuas lus kho qhov muag, 1550 nm InGaAsP/InP Distributed Feedback (DFB laser) EEL thiab 1300 nm InGaAsP/InGaP Fabry Pero EEL feem ntau siv ntawm qhov deb ntawm 2 km txog 40 km thiab qhov nrawm txog li 40 Gbps. Txawm li cas los xij, ntawm 60 m txog 300 m qhov deb ntawm qhov deb thiab qhov nrawm qis dua, VCsels raws li 850 nm InGaAs thiab AlGaAs yog cov tseem ceeb.
(2) Cov lasers uas muaj qhov ntsug thiab qhov nqaim muaj qhov zoo ntawm qhov me me thiab qhov ntev ntawm qhov ntev, yog li lawv tau siv dav hauv kev lag luam khoom siv hluav taws xob, thiab qhov ci ntsa iab thiab lub zog ntawm cov lasers semiconductor uas muaj ntug ci ntsa iab ua rau muaj kev siv rau kev soj ntsuam deb thiab kev ua haujlwm siab.
(3) Ob qho tib si ntug-emitting semiconductor lasers thiab ntsug cavity surface-emitting semiconductor lasers tuaj yeem siv rau luv - thiab nruab nrab-ntau liDAR kom ua tiav cov ntawv thov tshwj xeeb xws li kev nrhiav pom qhov chaw dig muag thiab kev tawm ntawm txoj kab.

5. Kev loj hlob yav tom ntej
Lub laser semiconductor emitting ntug muaj qhov zoo ntawm kev ntseeg siab siab, miniaturization thiab lub zog luminous siab, thiab muaj kev cia siab dav hauv kev sib txuas lus optical, liDAR, kev kho mob thiab lwm yam. Txawm li cas los xij, txawm hais tias cov txheej txheem tsim khoom ntawm cov lasers semiconductor edge-emitting tau loj hlob tuaj, txhawm rau kom tau raws li qhov kev thov ntawm kev lag luam thiab cov neeg siv khoom lag luam rau cov lasers semiconductor edge-emitting, nws yog qhov tsim nyog los txhim kho cov thev naus laus zis, cov txheej txheem, kev ua tau zoo thiab lwm yam ntawm cov lasers semiconductor edge-emitting, suav nrog: txo qhov tsis zoo hauv wafer; Txo cov txheej txheem txheej txheem; Tsim cov thev naus laus zis tshiab los hloov cov log sib tsoo ib txwm thiab cov txheej txheem txiav wafer hniav uas yooj yim ua rau muaj qhov tsis zoo; Txhim kho cov qauv epitaxial kom txhim kho kev ua haujlwm ntawm cov laser edge-emitting; Txo cov nqi tsim khoom, thiab lwm yam. Tsis tas li ntawd, vim tias lub teeb tso zis ntawm cov laser edge-emitting nyob rau ntawm ntug ntawm cov chip laser semiconductor, nws nyuaj rau ua tiav cov ntim me me, yog li cov txheej txheem ntim khoom cuam tshuam tseem yuav tsum tau tawg ntxiv.
