Hordhaca dalool toosan oo soo saaraya leysarka semiconductor (VCSEL)

Hordhaca dalool toosan oo soo baxayalaser semiconductor(VCSEL)
Laysarka tooska ah ee dusha sare ee dibadda ka soo baxa ayaa la sameeyay bartamihii 1990-meeyadii si looga gudbo dhibaato muhiim ah oo ragaadisay horumarinta leysarka semiconductor-dhaqameedka: sida loo soo saaro wax soo saarka laysarka awoodda sare leh oo leh tayo sare oo tayo sare leh oo ah qaabka aasaasiga ah.
Laysarada dusha sare ka saaraya dalool toosan oo dibadda ah (Vecsels), oo sidoo kale loo yaqaanleysarka semiconductor disc(SDL), waa xubin ku cusub qoyska laysarka. Waxay naqshadeyn kartaa hirarka dhererka qiiqa iyadoo la beddelayo halabuurka walxaha iyo dhumucda tirada si fiican ee dhexdhexaadiyaha semiconductor, oo lagu daro inta jeer ee intracavity labanlaabantay waxay dabooli kartaa mawjadaha dhererka ballaaran ee ultraviolet ilaa infrared fog, gaaritaanka soosaarka koronto sare iyadoo la ilaalinayo kala duwanaansho hoose Laydhka leysarka simmetrical xagal wareeg ah. Resonator laser wuxuu ka kooban yahay qaab dhismeedka DBR hoose ee gunta faa'iidada iyo muraayadda isku xidhka wax soo saarka dibadda. Qaab dhismeedkan resonator dibadda ah ee u gaarka ah waxa uu ogolaanayaa in walxaha indhaha la geliyo godka shaqada sida labanlaabida soo noqnoqda, kala duwanaanshaha soo noqnoqda, iyo hab-quful, taasoo ka dhigaysa VECSEL mid ku habboon.isha laysarkacodsiyada u dhexeeya biophotonics, spectroscopy,daawada laysarka, iyo saadaalinta laysarka.
Resonator-ka VC-korka sii deynaya laser semiconductor waa qumman yahay diyaaradda halkaas oo gobolka firfircoon ku yaal, iyo iftiinkeeda wax soo saarku waa siman yahay diyaaradda gobolka firfircoon, sida ku cad shaxanka.VCSEL waxay leedahay faa'iidooyin gaar ah, sida yar yar. cabbirka, soo noqnoqoshada sare, tayada alwaax wanaagsan, marinka waxyeelada dusha sare ee godka weyn, iyo habka wax soo saarka ee fudud. Waxay ku tusinaysaa waxqabad aad u fiican ee codsiyada bandhigga laysarka, isgaarsiinta indhaha iyo saacadda indhaha. Si kastaba ha ahaatee, VCsels ma heli karaan laysar awood sare leh oo ka sarreeya heerka watt, sidaas darteed looma isticmaali karo goobaha leh shuruudaha tamarta sare.

Resonator laser-ka ee VCSEL wuxuu ka kooban yahay dib-u-eegis Bragg ah (DBR) oo ka kooban qaab-dhismeedka epitaxial multi-lakabka ah ee walxaha semiconductor ee labada dhinac ee sare iyo hoose ee gobolka firfircoon, kaas oo aad uga duwan kanleysarkaresonator ka kooban diyaarad kala jeex ee EEL. Jihada resonator indhaha VCSEL waa la siman yahay in ay dusha chip, wax soo saarka laser sidoo kale waa la siman yahay in ay dusha chip, iyo milicsiga labada dhinac ee DBR aad u badan oo ka mid ah diyaaradda xal EEL.
Dhererka resonator laser ee VCSEL guud ahaan waa dhowr microns, taas oo aad uga yar tan milimitirka resonator ee EEL, iyo faa'iidada hal-jidka ah ee lagu helo oscillation field indhaha ee godka ayaa hooseeya. Inkasta oo wax-soo-saarka qaabka aasaasiga ah la gaari karo, awoodda wax-soo-saarka waxay gaari kartaa oo keliya dhowr milliwatts. Qaybta isdhaafka ah ee VCSEL wax soo saarka laysarka waa wareegto, iyo xagasha kala duwanaanshiyaha aad ayuu uga yar yahay kan iftiinka laysarka ee soo baxaya. Si loo gaaro koronto sare oo VCSEL ah, waxaa lagama maarmaan ah in la kordhiyo gobolka iftiinka si loo bixiyo faa'iido badan, kororka gobolka iftiinka wuxuu sababi doonaa laser-ka soo-saarka inuu noqdo wax soo saar badan oo qaab-dhismeed ah. Isla mar ahaantaana, way adag tahay in la gaaro duritaan isku mid ah oo hadda jira oo ku yaal gobol weyn oo iftiin leh, iyo cirbadeynta aan sinnayn ee hadda jirta waxay sii xumaynaysaa raasamaal kulaylka. Awoodda wax-soo-saarka ayaa hooseysa marka wax-soo-saarku uu yahay hal qaab. Sidaa darteed, VCsels badan ayaa inta badan lagu daraa habka wax-soo-saarka.
