4. Heerka codsiga ee leysarka semiconductor-ka-sii daaya
Mawjadda dhererkeeda ballaaran iyo awoodda sare awgeed, laser-ka-soo baxaya semiconductor ayaa si guul leh loogu dabaqay dhinacyo badan sida baabuurta, isgaarsiinta indhaha iyoleysarkadaaweynta. Marka loo eego horumarinta Yole, oo ah hay'ad cilmi baaris suuqeed oo caalami ah, suuqa laysarka ee cirifka-to-emit wuxuu kori doonaa $7.4 bilyan sanadka 2027, oo leh kobac sanadle ah oo isku dhafan oo ah 13%. Kobacani waxa uu sii wadi doonaa in uu dhaqaajiyo isgaadhsiinta indhaha, sida modules-yada indhaha, cod-qaadayaasha, iyo codsiyada dareenka 3D ee isgaarsiinta xogta iyo isgaarsiinta. Shuruudaha codsi ee kala duwan, nidaamyada naqshadaynta qaabdhismeedka EEL ee kala duwan ayaa lagu soo saaray warshadaha, oo ay ku jiraan: Fabripero (FP) lasers semiconductor lasers, Laysarka qaybinta Bragg Reflector (DBR), laser cavity lasers (ECL) laser semiconductor lasers, qaybinta jawaab celinta leysarka semiconductorDFB laser, leysarka quantum cascade semiconductor (QCL), iyo diodes laser aagga ballaaran (BALD).

Iyada oo ay sii kordheyso baahida loo qabo isgaarsiinta indhaha, codsiyada dareenka 3D iyo meelaha kale, baahida loo qabo laser-ka semiconductor ayaa sidoo kale sii kordhaya. Intaa waxaa dheer, leysarka semiconductor-ka soo baxaya ee gees-ka-baxa iyo laysarka-ka-soo-baxa dusha sare-sare waxay sidoo kale door ka ciyaaraan buuxinta cilladaha midba midka kale ee codsiyada soo baxaya, sida:
(1) Dhanka isgaarsiinta indhaha, 1550 nm InGaAsP / InP Dib-u-celinta Qaybinta (DFB laser) EEL iyo 1300 nm InGaAsP / InGaP Fabry Pero EEL ayaa inta badan loo isticmaalaa masaafada gudbinta ee 2 km ilaa 40 km iyo heerka gudbinta ilaa 40 Gbps 0 m, si kastaba ha ahaatee xawaaraha gudbinta ilaa 40 Gbps 3 m. VCsels ku salaysan 850 nm InGaAs iyo AlGaAs ayaa ugu badan.
(2) Laysarka tooska ah ee dusha sare ka soo baxaya waxay leeyihiin faa'iidooyinka cabbirka yar iyo dhererka hirarka cidhiidhiga ah, sidaa darteed si weyn ayaa loogu isticmaalay suuqa macaamiisha elektiroonigga ah, iyo faa'iidooyinka dhalaalka iyo awoodda laydhka soo saarista cidhifyada semiconductor-ka ayaa waddada u xaara codsiyada dareenka fog iyo farsamaynta awoodda sare.
(3) Laysarada-soo-saarka cidhifyada-ka-soo-baxa iyo leysarka-ka-baxa tooska ah ee dusha sare-saaraya laysarka semiconductor-ka waxaa loo isticmaali karaa gaaban-iyo dhexdhexaad ah liDAR si loo gaaro codsiyo gaar ah sida ogaanshaha indho-la'aanta iyo bixitaanka haadka.

5. Horumarka mustaqbalka
Laysarka cidhifka soo saaraysa semiconductor wuxuu leeyahay faa'iidooyinka isku halaynta sare, yaraynta iyo cufnaanta tamarta sare ee iftiinka, waxayna leedahay rajooyin ballaadhan oo xagga isgaarsiinta indhaha ah, liDAR, caafimaadka iyo qaybaha kale. Si kastaba ha ahaatee, in kasta oo habka wax soo saarka ee cidhifka soo saaraysa laysarka semiconductor uu ahaa mid bislaaday, si loo daboolo baahida sii kordheysa ee suuqyada warshadaha iyo macaamiisha ee laser-ka-soo-saarka cirifka, waxaa lagama maarmaan ah in si joogto ah loo hagaajiyo tignoolajiyada, habka, waxqabadka iyo qaybaha kale ee laser-ka-soo-saarka cidhifyada, oo ay ku jiraan: yaraynta cufnaanta cilladda gudaha waferka; In la yareeyo habraacyada habraaca; Samee tignoolajiyada cusub si aad u bedesho shiidida dhaqameedka iyo hababka goynta wafer ee u nugul inay soo bandhigaan cilladaha; Hagaajinta qaab-dhismeedka epitaxial si loo hagaajiyo waxtarka laser-ka-baxa; Iska yaree kharashyada wax soo saarka, iwm. Intaa waxaa dheer, sababtoo ah iftiinka wax soo saarka ee laysarka cidhifka ah ee soo saaraya wuxuu ku yaalaa dhinaca cidhifka laser-ka ee semiconductor, way adagtahay in la gaaro baakadaha yar yar ee baakadaha, markaa habka baakadaha ee la xidhiidha ayaa weli u baahan in la sii jebiyo.
