Isikhulisi sokubonauthotho: Intshayelelo kwi-Semiconductor Optical Amplifier
I-amplifier ye-semiconductor optical(SOA) yi-optical amplifier esekelwe kwi-semiconductor gain media. Ngokusisiseko ifana netyhubhu yelaser ye-semiconductor edityaniswe nefayibha, kunye nesipili sokugqibela esithatyathelwe indawo yifilimu echasene nokukhanya; Ii-waveguides ezithambekileyo zingasetyenziselwa ukunciphisa ngakumbi ukukhanya kokuphela. Ukukhanya kwesignali kudla ngokudluliselwa nge-semiconductor single-mode waveguide, enomlinganiselo osecaleni we-1-2 μ m kunye nobude obumalunga ne-0.5-2mm. Imo ye-waveguide ihambelana kakhulu nommandla osebenzayo (wokukhulisa), ophonswa yi-current. I-injecting current ivelisa uxinano oluthile lwe-carrier kwi-conduction band, okuvumela utshintsho lwe-optical ukusuka kwi-conduction band ukuya kwi-valence band. I-gain ephezulu yenzeka kwi-photon energy engaphezulu kancinci kwamandla e-bandgap.
Umgaqo wokusebenza we-amplifier ye-semiconductor optical
Izikhulisi ze-optical ze-semiconductor (I-SOA) zandisa imiqondiso yokukhanya okwenzekayo ngokukhupha okukhuthazwayo, kwaye indlela esebenza ngayo iyafana neyeeleser ze-semiconductor.Isikhulisi se-SOA opticalyilaser ye-semiconductor nje engenampendulo, kwaye eyona nto iphambili kukufumana inzuzo ye-optical ngokuguqula inani lamasuntswana xa i-amplifier ye-semiconductor optical iphampulwa nge-optical okanye ngombane.
Iintlobo zeI-amplifier ye-SOA Semiconductor optical
Ngokwendima edlalwa yi-SOA kwiinkqubo zabathengi, zingahlulwa zibe ziindidi ezine: i-serial, i-booster, i-switching SOA, kunye ne-preamplifier.
1. Ukufakwa ngokuthe ngqo: ukutyeba okuphezulu, i-Psat ephakathi; i-NF esezantsi kunye ne-PDG esezantsi, ngokuqhelekileyo inxulunyaniswa ne-polarisation ezimeleyo ye-SOA·
2. I-Enhancer: I-Psat ephezulu, inzuzo ephantsi, idla ngokuxhomekeka kwi-polarization;
3. Utshintsho: umlinganiselo ophezulu wokuphela kwezilwanyana kunye nexesha elikhawulezayo lokunyuka/lokuwa;
4. I-amplifier yangaphambili: ifanelekile kwiindlela ezinde zokudlulisela umbane, i-NF ephantsi, kunye ne-gain ephezulu.
Iingenelo ze-SOA Semiconductor optical amplifier
Inzuzo ye-optical enikezelwa yi-SOA ngaphakathi kwe-bandwidth ayixhomekekanga kakhulu kubude be-wavelength yesignali ye-optical yesiganeko.
Faka umsinga njengesignali yepompo eyandisiweyo, endaweni yokumpompa nge-optical.
Ngenxa yobukhulu bayo obuncinci, i-SOA inokudityaniswa nezixhobo ezininzi ze-photonic ze-waveguide kwi-substrate enye ejikelezileyo.
4. Basebenzisa ubuchwepheshe obufanayo nobe-diode lasers.
I-SOA ingasebenza kwiibhendi ze-communication spectral ze-1300 nm kunye ne-1550 nm, kunye ne-bandwidth ebanzi (ukuya kuthi ga kwi-100 nm).
6. Zingacwangciswa kwaye zihlanganiswe ukuze zisebenze njengee-preamplifiers kwisiphelo se-optical receiver.
I-SOA ingasetyenziswa njengesango le-logic elilula kwiinethiwekhi ze-optical ze-WDM.
Imida ye-SOA Semiconductor optical amplifier
I-SOA inokubonelela ngamandla okukhanya aphumayo ukuya kuthi ga kwi-milliwatts ezilishumi (mW), nto leyo edla ngokwanela ukusebenza kwetshaneli enye kwiikhonkco zonxibelelwano lwe-fiber optic. Nangona kunjalo, iinkqubo ze-WDM zinokufuna amandla afikelela kwi-mW ezininzi ngetshaneli nganye.
2. Ngenxa yokudibana kweefayibha ze-optical ezifakwayo ngaphakathi nangaphandle kweetships ezidityanisiweyo ze-SOA ezidla ngokubangela ukulahleka kwesiginali, i-SOA kufuneka ibonelele nge-optical gain eyongezelelweyo ukunciphisa impembelelo yale lahleko kwiinkalo zokufaka/zokukhupha kummandla osebenzayo.
I-SOA inovelwano kakhulu kwi-polarization yezibonakaliso ze-optical ezifakwayo.
4. Zivelisa amanqanaba aphezulu engxolo kwiindawo ezisebenzayo kunee-fiber amplifier.
Ukuba iitshaneli ezininzi ze-optical ziyandiswa njengoko kufuneka kwizicelo ze-WDM, i-SOA iya kubangela incoko enzima.
