Chidule cha kufunikira kwa laser ya DFB

Chidule cha kufunikira kwaLaza ya DFB
(1) Lingaliro lalikulu la laser ya DFB
Laser yopitilira ya DFB, yomwe imadziwikanso kuti mafunde opitilira kufalikiralaser ya semiconductor, imagwirizanitsa kapangidwe ka grating ka periodic mu gawo logwira ntchito la waveguide la laser. Podalira mphamvu yogawa ya grating, frequency selective resonance imatheka, ndipo laser imatulutsidwa mosalekeza komanso mosalekeza mu steady-state mode panthawi yonseyi, popanda kusokonezeka kwa pulse kapena kusinthasintha kwa mphamvu.
Poyerekeza ndi ma laser wamba a FP ndi ma laser a DFB oyendetsedwa ndi pulsed, ubwino wake waukulu ndi wodziwika kwambiri: choyamba, ili ndi kukhazikika kwamphamvu kwambiri kwa mafunde, imatha kupanga kutulutsa kolondola kwa mzere wopapatiza, ndipo imakana bwino kutentha kwa chilengedwe komanso kugwedezeka; Kachiwiri, mphamvu yotulutsa imakhala yokhazikika komanso yokhazikika, yokhala ndi malo apamwamba komanso phokoso lochepa kwambiri; Kachitatu, ili ndi mgwirizano wabwino, bandwidth yayikulu yosinthira, ndipo ndi yoyenera pazithunzi zosiyanasiyana za optoelectronic zokhala ndi mtunda wautali, kulondola kwambiri, komanso kukhazikika kwakukulu. Kutengera kusiyana kwa mawonekedwe, ma laser a DFB oyendetsedwa ndi pulsed amagwiritsidwa ntchito kwambiri polumikizirana ndi pulse, pomwe ma laser oyendetsedwa ndi DFB amayang'ana kwambiri zochitika zapamwamba zogwiritsidwa ntchito, zokhala ndi zopinga zaukadaulo zapamwamba komanso phindu lowonjezera lazinthu.
(2) Mbiri ya kufunikira kwa makampani
1. Kubwerezabwereza kwachangu kwa mauthenga a kuwala kwapangitsa kuti pakhale zosowa zofunika kwambiri
Netiweki yamagetsi yapadziko lonse lapansi, malo oyambira a 5G/6G, malo osungira deta, ndi maukonde a msana akukwera kufika pa liwiro lapamwamba kwambiri la 200G/400G/800G. Ma laser achikhalidwe sangakwaniritse zofunikira za kutumiza kwakutali komanso liwiro lotsika la zolakwika. Ma laser opitilira a DFB, monga gwero loyatsa la ma module othamanga kwambiri, ndi zinthu zofunika kwambiri kuti machitidwe olumikizirana othamanga kwambiri azigwira ntchito bwino.
2. Kusintha kwa masensa apamwamba kwambiri ku China kukufunika mwachangu
Magawo a fiber optic sensing, gasi detection, LiDAR, kufufuza mafuta, aerospace precision detection, ndi zina zotero ali ndi zofunikira kwambiri kuti mafunde azitha kulondola, kukhazikika, komanso moyo wautumiki wa nthawi yayitali.gwero la kuwala kwa laserKwa nthawi yayitali, ma laser apamwamba a DFB opitilira akhala akugwiritsa ntchito zinthu zochokera kunja, ndipo kufunikira kwa dzikolo kwa kulamulira kodziyimira pawokha kukupitirirabe, zomwe zikukakamiza kupita patsogolo kwaukadaulo mu unyolo wamakampani.
3. Kukulitsa mosalekeza zochitika zatsopano zogwiritsira ntchito
Magawo atsopano monga mankhwala a laser, kusanthula kolondola kwa ma spectral, kuzindikira kutentha kosalekeza kwa mafakitale, ndi kulumikizana kwa quantum zikukula mofulumira. Magwero owunikira a laser osasinthasintha, phokoso lochepa, ndi mzere wopapatiza wopingasa akhala ofala kwambiri, zomwe zimapangitsa kuti malo azikhala ochepa kwambiri mumakampani.
