Hordhac ku saabsan Laser-ka Ending Ending (EEL)
Si loo helo wax soo saar laysarka semiconductor-ka oo awood sare leh, tiknoolajiyada hadda jirta waa in la isticmaalo qaab-dhismeedka qiiqa geeska. Resonator-ka laysarka semiconductor-ka ee cidhifyada soo saaraya wuxuu ka kooban yahay dusha sare ee kala-goynta dabiiciga ah ee kiristaalka semiconductor-ka, iftiinka wax soo saarkana waxaa laga soo saaraa dhammaadka hore ee laysarka. laysarka semiconductor-ka nooca cidhifyada-soo-baxa wuxuu gaari karaa wax soo saar koronto oo sare, laakiin meesha wax soo saarkiisu waa elliptical, tayada laysarka waa liidataa, qaabka laysarkana waa in wax laga beddelaa iyadoo la adeegsanayo nidaam qaabayn laysar ah.
Jaantuska soo socda wuxuu muujinayaa qaab-dhismeedka leysarka semiconductor-ka ee cidhifka soo saaraya. Godka indhaha ee EEL wuxuu barbar socdaa dusha sare ee jajabka semiconductor-ka wuxuuna soo saaraa leysarka cidhifka jajabka semiconductor-ka, kaas oo xaqiijin kara wax soo saarka leysarka oo leh awood sare, xawaare sare iyo buuq hooseeya. Si kastaba ha ahaatee, wax soo saarka iftiinka leysarka ee EEL guud ahaan wuxuu leeyahay qayb isgoys ah oo aan sinnayn iyo kala duwanaansho xagal weyn, hufnaanta isku xidhka ee fiber-ka ama qaybaha kale ee indhaha waa mid hooseeya.

Kordhinta awoodda wax soo saarka EEL waxaa xaddidaya ururinta kulaylka qashinka ee gobolka firfircoon iyo dhaawaca indhaha ee dusha sare ee semiconductor-ka. Iyadoo la kordhinayo aagga hagaha hirarka si loo yareeyo ururinta kulaylka qashinka ee gobolka firfircoon si loo hagaajiyo kala-baxa kulaylka, kordhinta aagga wax soo saarka iftiinka si loo yareeyo cufnaanta awoodda indhaha ee iftiinka si looga fogaado waxyeelada indhaha, awoodda wax soo saarka ilaa dhowr boqol oo milliwatts ayaa lagu gaari karaa qaab-dhismeedka hagaha hirarka ee hal-ku-dhegga ah.
Hagaha hirarka 100mm, laysarka hal gees soo saaraya wuxuu gaari karaa tobanaan watts oo awood wax soo saar ah, laakiin waqtigan hagaha hirarku waa mid aad u badan oo ku yaal meesha jajabka, saamiga muuqaalka shucaaca wax soo saarkana wuxuu gaaraa 100:1, taasoo u baahan nidaam qaabeyn ah oo isku dhafan.
Iyadoo la tixgelinayo in aysan jirin horumar cusub oo ku yimid tignoolajiyada agabka iyo tignoolajiyada koritaanka epitaxial, habka ugu weyn ee lagu hagaajin karo awoodda wax soo saarka ee jajabka leysarka semiconductor-ka ah waa in la kordhiyo ballaca xariiqda ee gobolka iftiinka leh ee chip-ka. Si kastaba ha ahaatee, kordhinta ballaca xariiqda aad u sarreeya ayaa si fudud loo soo saari karaa gariirka qaabka sare ee isdhaafka ah iyo gariirka fiilooyinka u eg, taas oo si weyn u yareyn doonta isku-dhafka wax soo saarka iftiinka, awoodda wax soo saarkuna si siman uma kordho ballaca xariiqda, sidaa darteed awoodda wax soo saarka ee jajab keliya aad bay u xaddidan tahay. Si aad si weyn u horumariso awoodda wax soo saarka, tignoolajiyada safka ayaa soo baxda. Tignoolajiyadu waxay isku daraysaa cutubyo badan oo leysarka ah oo ku yaal isla substrate-ka, si cutub kasta oo iftiin soo saaraya loogu safeeyo sidii taxane hal-cabbir ah oo jihada dhidibka gaabiska ah, ilaa iyo inta tignoolajiyada go'doominta indhaha loo isticmaalo in lagu kala saaro cutub kasta oo iftiin soo saaraya oo ku jira safka, si aysan isu faragelin, adigoo samaynaya lasing badan oo dalool ah, waxaad kordhin kartaa awoodda wax soo saarka ee jajabka oo dhan adigoo kordhinaya tirada cutubyada iftiinka soo saaraya ee isku dhafan. Chip-kan laysarka semiconductor-ka ah waa chip-ka semiconductor laser array (LDA), oo sidoo kale loo yaqaan bar-ka semiconductor laser.
