Xulashada isha laysarka ee ugu habboon: laysarka semiconductor emission emission qaybta koowaad

Doorashada ugu fiicanIsha laysarka: Laser-ka semiconductor-ka ee qiiqa geeska
1. Hordhac
Laser-ka Semiconductor-ka ahJajabyada waxaa loo qaybiyaa jajabyada laysarka ee cidhifyada soo saara (EEL) iyo jajabyada laysarka ee dusha sare ee soo saara godka toosan (VCSEL) iyadoo loo eegayo hababka wax soo saarka ee kala duwan ee resonators-ka, kala duwanaansho qaab-dhismeedkooda gaarka ahna waxaa lagu muujiyay Jaantuska 1. Marka la barbardhigo laysarka dusha sare ee soo saara godka toosan, horumarinta tignoolajiyada laysarka semiconductor-ka ee cidhifyada soo saara waa mid aad u bisil, oo leh mawjad ballaaran, oo sarreeya.koronto-aragtiyeedWaxtarka beddelka, awoodda weyn iyo faa'iidooyin kale, aad ugu habboon habaynta laysarka, isgaarsiinta indhaha iyo qaybaha kale. Waqtigan xaadirka ah, laysarka semiconductor-ka ee cidhifyada ka soo baxaya waa qayb muhiim ah oo ka mid ah warshadaha optoelectronics, codsiyadooduna waxay dabooleen warshadaha, isgaarsiinta, sayniska, macaamiisha, militariga iyo hawada sare. Iyadoo la horumarinayo iyo horumarka tignoolajiyada, awoodda, isku halaynta iyo hufnaanta beddelka tamarta ee laysarka semiconductor-ka ee cidhifyada ka soo baxaya ayaa si weyn loo hagaajiyay, rajada codsigooduna aad ayay u sii ballaaran tahay.
Marka xigta, waxaan kuu horseedi doonaa inaad si qoto dheer u qadariso soo jiidashada gaarka ah ee soo saarista dhinaca-soo-saarkalaysarka semiconductor-ka.

2. Mabda'a shaqada ee semiconductor-ka qiiqa geeskalaysar
Qaab-dhismeedka leysarka semiconductor-ka ee gees-soo-saaraya waxaa loo qaybin karaa saddexda qaybood ee soo socda: gobolka firfircoon ee semiconductor-ka, isha bamka iyo resonator-ka indhaha. Marka laga reebo resonators-ka leysarka dusha sare ee godka toosan (kuwaas oo ka kooban muraayadaha Bragg ee sare iyo hoose), resonators-ka qalabka leysarka semiconductor-ka ee gees-soo-saaraya waxay inta badan ka kooban yihiin filimaan muuqaal ah oo labada dhinac ah. Qaab-dhismeedka qalabka EEL ee caadiga ah iyo qaab-dhismeedka resonator-ka waxaa lagu muujiyay Jaantuska 2. Foton-ka ku jira qalabka leysarka semiconductor-ka ee gees-soo-saaraya waxaa lagu xoojiyaa xulashada qaabka ee resonator-ka, leysarkana waxaa loo sameeyaa jihada barbar socota dusha sare ee substrate-ka. Qalabka leysarka semiconductor-ka ee gees-soo-saaraya waxay leeyihiin noocyo badan oo hirarka hawlgalka ah waxayna ku habboon yihiin codsiyo badan oo wax ku ool ah, sidaa darteed waxay noqdaan mid ka mid ah ilaha leysarka ee ugu habboon.

Tusmooyinka qiimaynta waxqabadka ee leysarka semiconductor-ka ee cidhifyada soo saaraya ayaa sidoo kale la jaanqaadaya leysarka kale ee semiconductor-ka, oo ay ku jiraan: (1) hirarka laser-ka ee laydhka; (2) Ith-ka hadda ee ugu sarreeya, taas oo ah, hadda uu diode-ka laser-ku bilaabo inuu soo saaro oscillation-ka laser-ka; (3) Iop-ka hadda shaqeeya, taas oo ah, hadda wadista marka diode-ka laser-ku uu gaaro awoodda wax soo saarka ee la qiimeeyay, halbeeggan waxaa lagu dabaqaa naqshadeynta iyo habaynta wareegga wadista laser-ka; (4) Waxtarka jiirada; (5) Kala-duwanaanshaha toosan Xagasha θ⊥; (6) Kala-duwanaanshaha Jiidaha Xagasha θ∥; (7) La soco Im-ka hadda jira, taas oo ah, cabbirka hadda ee chip-ka semiconductor-ka ee awoodda wax soo saarka ee la qiimeeyay.

3. Horumarka cilmi-baarista ee GaAs iyo laysarka semiconductor-ka ee ku salaysan GaN
Laser-ka semiconductor-ka ee ku salaysan walxaha semiconductor-ka ee GaAs waa mid ka mid ah teknoolojiyada laser-ka semiconductor-ka ugu bislaaday. Waqtigan xaadirka ah, laser-ka semiconductor-ka ee ku salaysan GAAS ee ku dhow infrared-ka (760-1060 nm) ayaa si weyn loogu isticmaalay ganacsi ahaan. Iyada oo ah walaxda semiconductor-ka ee jiilka saddexaad ka dib Si iyo GaAs, GaN waxay si weyn uga walaacsanayd cilmi-baarista sayniska iyo warshadaha sababtoo ah sifooyinka jireed iyo kiimikada ee aadka u fiican. Iyadoo la horumarinayo aaladaha optoelectronic-ka ee ku salaysan GAN iyo dadaalka cilmi-baarayaasha, diode-yada iftiinka soo saara ee ku salaysan GAN iyo leese-yada cidhifka soo saara ayaa la warshadeeyay.
