Kev piav qhia txog kev thov rau DFB laser

Kev piav qhia txog qhov xav tau rauDFB laser
(1) Lub tswv yim tseem ceeb ntawm DFB laser
DFB laser txuas ntxiv mus, tseem hu ua cov lus tawm tswv yim txuas ntxiv muslaser semiconductor, sib koom ua ke cov qauv grating periodic hauv thaj chaw waveguide nquag ntawm lub laser. Los ntawm kev cia siab rau cov nyhuv tawm tswv yim faib tawm ntawm lub grating, zaus xaiv resonance tau ua tiav, thiab lub laser raug tso tawm hauv hom kev ruaj khov tas mus li thiab tsis muaj kev cuam tshuam thoob plaws hauv tag nrho cov txheej txheem, tsis muaj kev cuam tshuam lub zog lossis kev hloov pauv ntawm lub zog ncov.
Piv nrog rau cov FP lasers ib txwm thiab cov pulsed DFB lasers, nws cov txiaj ntsig tseem ceeb yog qhov tseem ceeb heev: ua ntej, nws muaj qhov ruaj khov ntawm qhov ntev ntawm lub teeb, tuaj yeem ua tiav qhov tso zis ntawm cov kab nqaim, thiab muaj kev tiv thaiv zoo rau qhov kub thiab txias thiab kev cuam tshuam kev co; Qhov thib ob, lub zog tso zis yog tas mus li thiab ruaj khov, nrog qhov chaw zoo thiab lub suab qis heev; Qhov thib peb, nws muaj kev sib raug zoo, qhov bandwidth loj, thiab tsim nyog rau ntau yam optoelectronic scenes nrog qhov deb ntev, qhov tseeb siab, thiab kev ruaj khov siab. Raws li qhov sib txawv ntawm cov yam ntxwv, pulsed DFB lasers feem ntau siv rau kev sib txuas lus thiab kev sib txuas lus pulse, thaum DFB lasers tas mus li tsom mus rau qhov kawg ruaj khov-xeev daim ntawv thov scenarios, nrog rau cov teeb meem kev siv tshuab siab dua thiab cov khoom ntxiv tus nqi.
(2) Keeb kwm yav dhau los ntawm kev thov kev lag luam
1. Kev sib txuas lus ceev ceev ntawm kev sib txuas lus kho qhov muag tau ua rau muaj kev xav tau ceev ceev
Lub network fais fab thoob ntiaj teb, 5G/6G chaw nres tsheb, cov chaw khaws ntaub ntawv, thiab cov network backbone tab tom hloov kho mus rau qhov ceev ceev ntawm 200G/400G/800G. Cov lasers ib txwm tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev sib kis mus deb thiab qhov yuam kev tsawg. DFB lasers txuas ntxiv mus, ua lub hauv paus emitting lub teeb ntawm cov modules optical ceev ceev, yog cov khoom tseem ceeb rau kev ua haujlwm ruaj khov ntawm cov kab ke sib txuas lus optical ceev ceev.
2. Kev hloov chaw ntawm cov khoom siv high-end hauv Suav teb yog qhov xav tau sai sai
Cov teb ntawm fiber optic sensing, roj nrhiav, LiDAR, roj av tshawb nrhiav, aerospace precision nrhiav, thiab lwm yam muaj cov kev cai nruj rau qhov tseeb ntawm wavelength, kev ruaj khov, thiab lub neej ua haujlwm ntawmlub teeb laserTau ntev heev, cov lasers DFB txuas ntxiv mus tau vam khom kev xa khoom tuaj, thiab qhov kev thov hauv tsev rau kev tswj hwm tus kheej txuas ntxiv mus ntxiv, yuam kev tsim kho tshiab hauv kev lag luam.
3. Txuas ntxiv nthuav dav cov xwm txheej thov tshiab
Cov teb tshiab xws li kev kho mob laser, kev tshuaj xyuas spectral precision, kev ntsuas kub tas li hauv kev lag luam, thiab kev sib txuas lus quantum tab tom loj hlob sai. Lub teeb laser txuas ntxiv mus tas li, suab nrov tsawg, thiab kab nqaim tau dhau los ua tus qauv hauv qhov chaw, txuas ntxiv qhib qhov chaw ntxiv hauv kev lag luam.
