4. Imiterere y'ikoreshwa rya lasers semiconductor emissions edge-emission
Kubera ko ifite uburebure bunini bw'uburebure bw'umurambararo n'imbaraga nyinshi, laser za semiconductor zisohora imipaka zakoreshejwe neza mu nzego nyinshi nko mu bijyanye n'imodoka, itumanaho ry'amajwi n'ikoranabuhanga.laserubuvuzi. Nk’uko Yole Developpement, ikigo cy’ubushakashatsi ku isoko kizwi ku rwego mpuzamahanga, isoko rya laser rishobora gukura rikagera kuri miliyari 7.4 z’amadolari mu 2027, hamwe n’igipimo cy’iterambere ry’umwaka cya 13%. Iri zamuka rizakomeza guterwa n’itumanaho ry’amajwi, nka modules optical, amplifiers, na porogaramu zo kumenya amakuru ya 3D mu itumanaho ry’amakuru n’itumanaho. Ku bijyanye n’ibisabwa bitandukanye mu ikoranabuhanga, gahunda zitandukanye zo gushushanya imiterere ya EEL zarakozwe muri uru rwego, harimo: lasers semiconductor za Fabripero (FP), lasers semiconductor za Distributed Bragg Reflector (DBR), lasers semiconductor za external cavity (ECL), lasers semiconductor za distributed feedback semiconductor (Lazeri ya DFB), laser za quantum cascade semiconductor (QCL), na diode za laser zo mu gace kagutse (BALD).

Kubera ko icyifuzo cy’itumanaho ry’amatara (optical communication), porogaramu zo gupima 3D n’izindi nzego zirimo kwiyongera, icyifuzo cya laser za semiconductor nacyo kiriyongera. Byongeye kandi, laser za semiconductor zitanga imirasire y’izuba n’izitanga imirasire y’izuba ihagaze neza nabyo bigira uruhare mu kuzuza intege nke za buri wese mu mikoreshereze mishya, nka:
(1) Mu rwego rw'itumanaho rya optique, 1550 nm InGaAsP/InP Distributed Feedback ((DFB laser) EEL na 1300 nm InGaAsP/InGaP Fabry Pero EEL ikunze gukoreshwa mu ntera ya 2 km kugeza kuri 40 km kandi ikwirakwira rya 40 Gbps. Ariko, ku ntera ya 60 m kugeza kuri 300 m n'umuvuduko muto wa diyasiyo, VCsel zishingiye kuri 850 nm InGaAs na AlGaAs ni zo ziganje.
(2) Imashini zisohora ubuso zihagaze zifite ibyiza byo kuba ntoya kandi zifite uburebure buto, bityo zikaba zarakoreshejwe cyane ku isoko ry’ibikoresho by’ikoranabuhanga, kandi ibyiza by’urumuri n’imbaraga bya laser za semiconductor zisohora ubushyuhe mu ntera bitanga inzira yo gukoresha mu gupima kure no gutunganya ingufu nyinshi.
(3) Lazeri zombi zikoresha imirasire y'izuba n'izikoresha imirasire y'izuba ihagaze ku butaka ishobora gukoreshwa ku buryo bworoshye no mu buryo buciriritse kugira ngo igere ku bikorwa byihariye nko kubona aho ibintu biherereye no kuva mu nzira.

5. Iterambere ry'ejo hazaza
Laser ya semiconductor isohora imirasire ifite ibyiza byo kwizerwa cyane, miniaturization no kuba ifite imbaraga nyinshi z'urumuri, kandi ifite amahirwe menshi yo gukoreshwa mu itumanaho ry'amajwi, liDAR, ubuvuzi n'izindi nzego. Ariko, nubwo inzira yo gukora laser ya semiconductor isohora imirasire ...
