4. Daim ntawv thov txheej xwm ntawm ntug-emission semiconductor lasers
Vim nws qhov dav wavelength ntau thiab lub zog siab, ntug-emitting semiconductor lasers tau ua tiav nyob rau hauv ntau lub teb xws li tsheb, kev sib txuas lus kho qhov muag thiablaserkev kho mob. Raws li Yole Developpement, lub koom haum tshawb fawb kev lag luam thoob ntiaj teb, kev lag luam ntug-rau-emit laser yuav loj hlob mus txog $ 7.4 billion hauv 2027, nrog rau kev loj hlob txhua xyoo ntawm 13%. Qhov kev loj hlob no tseem yuav tau tsav los ntawm kev sib txuas lus kho qhov muag, xws li optical modules, amplifiers, thiab 3D sensing applications rau cov ntaub ntawv sib txuas lus thiab kev sib txuas lus. Rau cov ntawv thov sib txawv, cov qauv tsim EEL sib txawv tau tsim nyob rau hauv kev lag luam, suav nrog: Fabripero (FP) semiconductor lasers, Distributed Bragg Reflector (DBR) semiconductor lasers, sab nraud kab noj hniav laser (ECL) semiconductor lasers, faib tawm tswv yim semiconductor lasers (DFB laser), quantum cascade semiconductor lasers (QCL), thiab dav cheeb tsam laser diodes (BALD).

Nrog rau kev thov ntau ntxiv rau kev sib txuas lus kho qhov muag, 3D sensing daim ntaub ntawv thiab lwm yam kev lag luam, qhov kev thov rau semiconductor lasers kuj nce. Tsis tas li ntawd, ntug-emitting semiconductor lasers thiab ntsug-cavity nto-emitting semiconductor lasers kuj ua lub luag haujlwm hauv kev sau ib leeg qhov tsis txaus 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 kev sib kis ntawm 2 km txog 40 km thiab kis tau tus nqi mus txog 40 Gbps Txawm li cas los xij, ntawm 60 m rau 300 m kis tau tus mob thiab qis kis ceev, VCsels raws li 850 nm InGaAs thiab AlGaAs yog qhov tseem ceeb.
(2) Ntsug kab noj hniav nto-emitting lasers muaj qhov zoo ntawm qhov me me thiab nqaim wavelength, yog li lawv tau siv dav hauv kev lag luam khoom siv hluav taws xob, thiab qhov ci ntsa iab thiab lub zog zoo ntawm ntug emitting semiconductor lasers pave txoj kev rau tej thaj chaw deb sensing daim ntaub ntawv thiab kev ua haujlwm siab.
(3) Ob leeg ntug-emitting semiconductor lasers thiab ntsug kab noj hniav nto-emitting semiconductor lasers tuaj yeem siv luv luv - thiab nruab nrab-ntau liDAR kom ua tiav cov kev siv tshwj xeeb xws li qhov muag tsis pom qhov muag thiab txoj kev tawm mus.

5. Kev txhim kho yav tom ntej
Lub ntug emitting semiconductor laser muaj qhov zoo ntawm kev ntseeg siab, miniaturization thiab siab luminous zog ntom, thiab muaj cov ntawv thov dav dav hauv kev sib txuas lus kho qhov muag, liDAR, kev kho mob thiab lwm yam. Txawm li cas los xij, txawm hais tias kev tsim cov txheej txheem ntawm ntug-emitting semiconductor lasers tau paub tab, txhawm rau kom ua tau raws li qhov xav tau ntawm kev lag luam thiab cov neeg siv khoom lag luam rau ntug-emitting semiconductor lasers, nws yog ib qho tsim nyog yuav tsum ua kom zoo dua qub rau kev siv tshuab, txheej txheem, kev ua haujlwm thiab lwm yam. yam ntawm ntug-emitting semiconductor lasers, xws li: txo qhov tsis xws luag nyob rau hauv lub wafer; Txo cov txheej txheem txheej txheem; Tsim cov thev naus laus zis tshiab los hloov cov tsoos sib tsoo lub log thiab cov txheej txheem wafer txiav cov txheej txheem uas nquag ua kom paub qhov tsis xws luag; Optimize lub epitaxial qauv los txhim kho efficiency ntawm ntug-emitting laser; Txo cov nqi tsim khoom, thiab lwm yam ntxiv, vim tias lub teeb pom kev ntawm ntug-emitting laser nyob rau sab ntug ntawm semiconductor laser nti, nws yog ib qho nyuaj rau kev ua tiav cov ntim me me, yog li cov txheej txheem ntim khoom tseem yuav tsum tau ua. ntxiv tawg los ntawm.
