Hordhac Laser Emitting Laser (EEL)
Si loo helo wax soo saarka laser semiconductor awood sare leh, tignoolajiyada hadda jirta waa in la isticmaalo qaab dhismeedka qiiqa qiiqa. Resonator-ka laser-ka-soo-baxa semiconductor-ka wuxuu ka kooban yahay dusha kala-baxa dabiiciga ah ee crystal semiconductor, iyo laydhka wax-soo-saarka ayaa ka soo baxaya cidhifka hore ee laser. Meesha wax-soo-saarku waa elliptical, tayada beybaarku waa liidataa, waxaana loo baahan yahay in qaab-dhismeedku wax-ka-beddelo iyadoo la adeegsanayo hab-qaabaynta iftiinka.
Jaantuska soo socdaa waxa uu tusinayaa qaab dhismeedka leysarka cidhifka soo baxaya. Godka indhaha ee EEL wuxuu la mid yahay dusha sare ee chip semiconductor wuxuuna sii daayaa leysarka cidhifka semiconductor-ka, kaas oo xaqiijin kara wax soo saarka laysarka oo leh awood sare, xawaare sare iyo buuq hoose. Si kastaba ha ahaatee, wax soo saarka laysarka ee EEL guud ahaan waxa uu leeyahay qaybta iskutallaabta ee laydhka asymmetrical iyo kala duwanaansho xagal weyn ah, iyo waxtarka isku-xidhka fiber-ka ama qaybaha kale ee indhaha ayaa hooseeya.

Korodhka awoodda wax-soo-saarka EEL waxay ku xaddidan tahay ururinta kulaylka qashinka ee gobolka firfircoon iyo dhaawaca indhaha ee dusha sare ee semiconductor. Iyadoo la kordhinayo aagga waveguide si loo yareeyo ururinta kulaylka qashinka ee gobolka firfircoon si loo hagaajiyo kuleylka kuleylka, kordhinta aagga iftiinka iftiinka si loo yareeyo cufnaanta awoodda indhaha ee iftiinka si looga fogaado dhaawaca indhaha, awoodda wax soo saarka ilaa dhowr boqol oo milliwatts lagu gaaro qaab-dhismeedka mawjadaha hal-abuurka ah
100mm waveguide, hal cidhif-saarid laser ah ayaa gaari kara tobanaan watts oo awood wax soo saar ah, laakiin waqtigan waveguide waa mid aad u badan oo ku jira diyaaradda chip-ka, iyo saamiga wax soo saarka ee wax soo saarka ayaa sidoo kale gaaraya 100: 1, oo u baahan nidaam qaabaynta alwaax adag.
Marka la eego in aysan jirin horumar cusub oo ku saabsan tignoolajiyada agabka iyo tignoolajiyada kobaca epitaxial, habka ugu weyn ee lagu wanaajin karo awoodda wax soo saarka ee hal chip laser semiconductor waa in la kordhiyo ballaadhka xariijinta gobolka iftiinka ee chip-ka. Si kastaba ha ahaatee, kordhinta width strip aad u sarreeya waa ay fududahay in la soo saaro transverse sare-dalbashada hab oscillation iyo oscillation filamentlike, taas oo si weyn u yaraynaysaa isku midka ah ee wax soo saarka iftiinka, iyo awoodda wax soo saarka ma kordhin si saami la width strip ah, sidaas darteed awoodda wax soo saarka ee hal jajab aad buu u xaddidan yahay. Si aad u wanaajiso awoodda wax soo saarka, tignoolajiyada diyaarinta ayaa soo baxda. Tignoolajiyadu waxay isku xidhaa unugyo badan oo leysarka isla substrate-ka, si unug kasta oo iftiimaya uu u safan yahay sidii hal-beeg-beeg ah oo jihada dhidibka qunyar u ah, ilaa inta tignoolajiyada go'doominta indhaha la isticmaalayo si loo kala saaro unug kasta oo iftiimiya laydhka. , si aanay u faragelin midba midka kale, samaynta lasing multi-aperture ah, waxaad kordhin kartaa awoodda wax soo saarka ee chip oo dhan by kordhinta tirada unugyada iftiiminta isku dhafan. Chip laser semiconductor waa chip array laser semiconductor (LDA), sidoo kale loo yaqaan bar laser semiconductor.
