Kusankha KwabwinoGwero la Laser: Kutulutsa M'mphepeteSemiconductor laserGawo Lachiwiri

4. Mkhalidwe wogwiritsira ntchito ma lasers a emission semiconductor lasers
Chifukwa cha kutalika kwake kwa kutalika kwake komanso mphamvu zake zambiri, ma laser a semiconductor otulutsa m'mphepete adagwiritsidwa ntchito bwino m'magawo ambiri monga magalimoto, kulumikizana kwa kuwala ndi kuwala.laserchithandizo chamankhwala. Malinga ndi Yole Developpement, bungwe lodziwika bwino la kafukufuku wamsika padziko lonse lapansi, msika wa laser-to-emit laser udzakula mpaka $ 7.4 biliyoni mu 2027, ndikukula kwapachaka kwa 13%. Kukula kumeneku kudzapitirizabe kuyendetsedwa ndi mauthenga a kuwala, monga ma modules optical, amplifiers, ndi 3D sensing applications for data communications and telecommunications. Pazofunikira zosiyanasiyana zogwiritsira ntchito, machitidwe osiyanasiyana a EEL apangidwa m'makampani, kuphatikizapo: Fabripero (FP) semiconductor lasers, Distributed Bragg Reflector (DBR) semiconductor lasers, external cavity laser (ECL) semiconductor lasers, kugawa ndemanga semiconductor lasers (DFB laser) , quantum cascade semiconductor lasers (QCL), ndi wide area laser diode (BALD).

Pakuchulukirachulukira kwa kulumikizana kwa kuwala, kugwiritsa ntchito ma sensor a 3D ndi magawo ena, kufunikira kwa ma semiconductor lasers kukuchulukiranso. Kuphatikiza apo, ma lasers a semiconductor otulutsa m'mphepete ndi ma vertical-cavity surface-emitting semiconductor lasers amathandizanso kudzaza zolakwika za wina ndi mnzake pamapulogalamu omwe akubwera, monga:
(1) Pankhani ya optical communications, 1550 nm InGaAsP/InP Distributed Feedback ( (DFB laser) EEL ndi 1300 nm InGaAsP/InGaP Fabry Pero EEL amagwiritsidwa ntchito kawirikawiri pamtunda wa 2 km mpaka 40 km ndi maulendo opatsirana mpaka 40 Gbps Komabe, pa 60 m mpaka 300 m mtunda wotumizira komanso kuthamanga kwapang'onopang'ono, VCsels yochokera ku 850 nm InGaAs ndi AlGaAs ndizovuta.
(2) Ma lasers ofukula pamwamba-emitting lasers ali ndi ubwino wocheperako komanso kutalika kocheperako, kotero akhala akugwiritsidwa ntchito kwambiri pamsika wamagetsi ogula, ndipo kuwala ndi ubwino wa mphamvu za lasers zotulutsa semiconductor zimatsegula njira yogwiritsira ntchito zomverera zakutali. high-power processing.
(3) Ma lasers a semiconductor otulutsa m'mphepete ndi ma lasers of the semiconductor lasers atha kugwiritsidwa ntchito kwakanthawi kochepa - komanso sing'anga-sing'anga liDAR kuti akwaniritse ntchito zina monga kuzindikira malo akhungu ndi kunyamuka kwa msewu.

5. Chitukuko chamtsogolo
M'mphepete emitting semiconductor laser ili ndi ubwino wodalirika kwambiri, miniaturization ndi kachulukidwe kakang'ono ka mphamvu, ndipo imakhala ndi chiyembekezo chogwiritsa ntchito pakulankhulana kwa kuwala, liDAR, zamankhwala ndi zina. Komabe, ngakhale njira yopangira ma lasers a semiconductor lasers yakhala yokhwima, kuti akwaniritse kufunikira kwa msika wamafakitale ndi ogula kwa ma lasers otulutsa semiconductor, ndikofunikira kupitiliza kukhathamiritsa ukadaulo, njira, magwiridwe antchito ndi zina. mbali za lasers za semiconductor zotulutsa m'mphepete, kuphatikiza: kuchepetsa kachulukidwe kachilema mkati mwa chowotcha; Kuchepetsa ndondomeko ya ndondomeko; Kupanga matekinoloje atsopano kuti alowe m'malo mwa gudumu lopera lakale ndi njira zodulira masamba omwe amakonda kuyambitsa zolakwika; Konzani mawonekedwe a epitaxial kuti apititse patsogolo mphamvu ya laser yotulutsa m'mphepete; Chepetsani ndalama zopangira, etc. Komanso, chifukwa kuwala linanena bungwe la m'mphepete-emitting laser ndi pa mbali m'mphepete mwa semiconductor laser Chip, n'zovuta kukwaniritsa ang'onoang'ono kukula Chip ma CD, kotero ma CD ogwirizana ndondomeko akadali kofunika. zinadutsanso.
