Waa maxay acod-weyneeye indho-indheyn
Cod-weyneeye-indho-conductor waa nooc ka mid ah cod-weyneeye indhaha oo isticmaala dhexdhexaad-helid-helid. Waxay la mid tahay diode leysarka, kaas oo muraayadda ku taal dhamaadka hoose lagu beddelo dahaarka semi-milicsiga. Iftiinka calaamada waxa lagu kala qaadaa mawjadaha hal-hab ee semiconductor. Cabirka leexsan ee waveguide waa 1-2 micrometer, dhererkiisuna waa 0.5-2mm. Habka waveguide waxa uu leeyahay isku-xirnaan la taaban karo oo leh gobolka firfircoon (amplification), kaas oo ay ku shubto hadda. Hadda la isku duray waxa ay abuurtaa xoog-ururin qaade gaar ah oo ku jira band-wadaha, taas oo u oggolaanaysa kala-guurka indhaha ee band-wadaha ilaa kooxda valence. Faa'iidada ugu sarreysa waxay timaadaa marka tamarta photon ay wax yar ka weyn tahay tamarta bandgap. Cod-weyneeye indhaha SOA waxa sida caadiga ah loo adeegsadaa nidaamyada isgaarsiinta qaab doofaarro ah, oo leh mowjad dhererkeedu yahay 1300nm ama 1500nm, taasoo bixisa ku dhawaad 30dB oo faa'iido ah.
TheSOA semiconductor optical amplifierwaa aaladda isku xirka PN oo leh qaab-dhismeedka ceelka tirada cufan. Eexda hore ee dibadda waxay beddeshaa tirada qaybaha dielectric. Ka dib markii iftiinka kicinta dibadda uu soo galo, shucaac la kiciyay ayaa soo baxaya, taasoo lagu gaaro kor u qaadista calaamadaha indhaha. Dhammaan saddexda hab ee wareejinta tamarta ee kor ku xusan ayaa ku jiraCod-weyneeye indhaha SOA. Kordhinta calaamadaha indhaha waxay ku salaysan yihiin qiiqa la kiciyey. Nuugista la kiciyey iyo hababka qiiqa la kiciyey ayaa isku mar jira. Nuugista la kiciyay ee iftiinka bamka waxaa loo isticmaali karaa si loo dardargeliyo dib u soo kabashada sidayaal, isla markaana, bamka korantada wuxuu u diri karaa elektarooniga heer sare oo tamar ah (band conduction). Marka shucaaca kediska ah la kordhiyo, wuxuu samayn doonaa dhawaaq shucaac iskiis ah oo la kordhiyey. Cod-weyneeye indhaha SOA wuxuu ku salaysan yahay chips semiconductor.
Chips Semiconductor waxay ka kooban yihiin semiconductors, sida GaAs/AlGaAs, InP/AlGaAs, InP/InGaAsP iyo InP/InAlGaAs, iwm. Naqshadaynta waveguide ee SOA waxay la mid tahay ama la mid tahay tan laysarka. Farqiga ayaa ku jira in leysarka ay u baahan yihiin inay sameeyaan dalool resonant agagaarka faa'iidada dhexdhexaadka ah si ay u abuuraan oo ay u ilaaliyaan oscillation ee isha isha. Calaamadaha indhaha ayaa lagu kordhin doonaa dhowr jeer godka ka hor inta aan la soo saarin. GudahaCod-weyneeye SOA(waxa aan halkan kaga hadlayno waxay ku kooban yihiin cod-weyneyaasha mowjadaha socdaalka ee loo isticmaalo codsiyada badankooda), iftiinku wuxuu u baahan yahay oo kaliya inuu dhex maro dhexdhexaadka faa'iidada hal mar, iyo dib u milicsiga waa mid aad u yar. Qaab dhismeedka cod-weyneeye SOA wuxuu ka kooban yahay saddex meelood: Aagga P, Aagga I (lakabka firfircoon ama qanjidhada), iyo Aagga N. Lakabka firfircoon wuxuu inta badan ka kooban yahay Quantum Wells, kaas oo hagaajin kara waxtarka beddelka sawir-qaadista wuxuuna yareynayaa heerka hadda jira.

Codsaday wareejinta kanaalka
SOA-yada badanaa laguma dabaqo oo keliya xoojinta: sidoo kale waxaa loo isticmaali karaa goobta isgaarsiinta fiber indhaha, codsiyada ku saleysan hababka aan tooska ahayn sida faa'iidada saturation ama polarization-wajiga, kuwaas oo ka faa'iideysanaya kala duwanaanshaha xoojinta side ee cod-weyneeye indhaha SOA si loo helo tusmooyinka dib-u-celinta ee kala duwan. Saamayntan waxaa lagu dabaqi karaa wareejinta kanaalka (beddelka hirarka dhererka), beddelka qaab beddelka, soo kabashada saacadda, dib-u-soo-nooleynta calaamadaha iyo aqoonsiga qaabka, iwm. ee nidaamka isku-dhufashada mawjada dhererka.
Iyadoo horumarinta tignoolajiyada isku dhafan ee optoelectronic iyo hoos u dhigista kharashyada wax soo saarka, goobaha codsiga ee SOA semiconductor optical amplifiers sida cod-weyneyaasha aasaasiga ah, qalabka indhaha ee shaqeynaya iyo qaybaha nidaamka hoose ayaa sii wadi doona ballaarinta.
