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. Dib-u-kicinta laser-ka-soo-saarka cirifka-soo-saarka laser-ka wuxuu ka kooban yahay dusha kala-baxa dabiiciga ah ee crystal semiconductor, iyo iftiinka wax soo saarka wuxuu ka soo baxayaa dhamaadka hore ee laser-ka.
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 kulaylka, kordhinta aagga iftiinka iftiinka si loo yareeyo cufnaanta awoodda indhaha ee laydhka si looga fogaado waxyeellada indhaha, awoodda wax soo saarka ilaa dhowr boqol oo milliwatts ayaa lagu gaari karaa qaab-dhismeedka qaab-dhismeedka hal-abuurka ah.
100mm waveguide, hal cidhif soo saaraysa laysar wuxuu gaari karaa tobanaan watts oo awood wax soo saar ah, laakiin waqtigan waveguide waa mid aad u badan oo ku jira diyaaradda chip-ka, saamiga wax-soo-saarka wax-soo-saarka sidoo kale wuxuu gaarayaa 100: 1, wuxuu u baahan yahay nidaam qaabeyn oo 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 filamentlike oscillation, taas oo si weyn u yarayn doona la mid ah wax soo saarka iftiinka, iyo awoodda wax soo saarka ma korodho saami la width strip ah, sidaas darteed awoodda wax soo saarka ee hal chip waa mid aad u xaddidan. Si aad u wanaajiso awoodda wax soo saarka, tignoolajiyada diyaarinta ayaa soo baxda. Tiknoolajiyadu waxay isku xidhaa unugyo laser badan oo isku mid ah, sidaa darteed unug kasta oo iftiimiya wuxuu u safan yahay qaab hal-cabbir ah oo ku yaal jihada dhidibka gaabis ah, ilaa inta tikniyoolajiyadda go'doominta indhaha loo isticmaalo in lagu kala saaro unug kasta oo iftiiminaya laydhka, si aanay u faragelin midba midka kale, samaynta lasing multi-aperture, waxaad kordhin kartaa soo saarista tirada kororka iftiinka ee tirada unugyada isku dhafan. Chip laser semiconductor waa chip array laser semiconductor (LDA), sidoo kale loo yaqaan bar laser semiconductor.
