Iphuculwei-amplifier ye-optical ye-semiconductor

I-amplifier ye-semiconductor ephuculweyo yinguqulelo ephuculweyo ye-amplifier ye-semiconductor optical (Isikhulisi se-SOA optical). Yi-amplifier esebenzisa ii-semiconductors ukubonelela nge-gain medium. Ulwakhiwo lwayo lufana nolwe-Fabry-Pero laser diode, kodwa ngokuqhelekileyo ubuso bokugqibela bugqunywe ngefilimu echasene nokukhanya. Uyilo lwamva nje luquka iifilimu ezichasene nokukhanya kunye nee-waveguides ezithambekileyo kunye neendawo zeefestile, ezinokunciphisa ukukhanya kobuso bokugqibela ukuya ngaphantsi kwe-0.001%. Ii-amplifier ze-optical eziphuculweyo ezisebenzayo ziluncedo kakhulu xa kwandiswa imiqondiso (ye-optical), njengoko kukho umngcipheko omkhulu wokulahleka kwesignali ngexesha lokudluliselwa komgama omde. Ekubeni isignali ye-optical ikhuliswa ngokuthe ngqo, indlela yendabuko yokuyiguqula ibe yisignali yombane ngaphambi kokuba ingasebenzi. Ke ngoko, ukusetyenziswa kweI-SOAiphucula kakhulu ukusebenza kakuhle kothumelo. Le teknoloji idla ngokusetyenziselwa ukwahlulwa kwamandla kunye nokuhlawula ilahleko kwiinethiwekhi zeWDM.

Iimeko zesicelo

Kwiinkqubo zonxibelelwano lwefayibha ye-optical, ii-amplifier ze-optical ze-semiconductor (i-SOA) zingasetyenziswa kwiindawo ezininzi zokusetyenziswa ukuphucula ukusebenza kunye nomgama wokudluliselwa kwenkqubo yonxibelelwano. Ezi zilandelayo zezinye zeendlela eziqhelekileyo zokusebenzisa i-amplifier ye-SOA kwiinkqubo zonxibelelwano lwefayibha ye-optical:

I-Preamplifier: SOAi-amplifier yokukhanyaingasetyenziswa njenge-preamplifier kwindawo yokufumana i-optical kwiinkqubo zonxibelelwano ezikude ezinee-optical fibers ezidlula iikhilomitha ezili-100, nto leyo ephucula okanye ikhulisa amandla okukhupha isignali kwiinkqubo zonxibelelwano lwe-optical fibers ezikude, ngaloo ndlela ihlawulela umgama ongaphelelanga wokudlulisela obangelwa kukuphuma okubuthathaka kwemiqondiso emincinci. Ngaphezu koko, i-SOA ingasetyenziselwa ukuphumeza itekhnoloji yokuvuselela isignali yenethiwekhi ye-optical kwiinkqubo zonxibelelwano lwe-optical fiber.

Ukuvuselelwa kwesignali ye-optical yonke: Kwiinethiwekhi ze-optical, njengoko umgama wokudluliselwa usanda, imiqondiso ye-optical iya konakala ngenxa yokuncipha, ukusasazwa, ingxolo, i-time jitter kunye ne-crosstalk, njl. Ke ngoko, ekudlulisweni komgama omde, kuyimfuneko ukuhlawula imiqondiso ye-optical eyonakeleyo ukuqinisekisa ukuchaneka kolwazi oludluliselweyo. Ukuhlaziywa kwesignali ye-optical yonke kubhekisa ekukhuliseni kwakhona, ukuphinda kubunjwe kunye nokuphinda kube lixesha. Ukwandiswa okungakumbi kunokufezwa zi-optical amplifiers ezifana ne-semiconductor optical amplifiers, i-EDFA kunye ne-Raman amplifiers (RFA).

Kwiinkqubo zokuva ifayibha ye-optical, ii-amplifier ze-optical ze-semiconductor (Isikhulisi se-SOA) ingasetyenziselwa ukukhulisa imiqondiso ye-optical, ngaloo ndlela iphucula ubuntununtunu kunye nokuchaneka kwee-sensors. Ezi zilandelayo zezinye zeendlela eziqhelekileyo zokusebenzisa i-SOA kwiinkqubo zokuva i-optical fiber:

Ukulinganiswa koxinzelelo lwefayibha yokukhanya: Lungisa ifayibha yokukhanya kwinto ekufuneka ilinganiswe uxinzelelo lwayo. Xa into iphantsi koxinzelelo, utshintsho loxinzelelo luya kubangela utshintsho oluncinci kubude befayibha yokukhanya, ngaloo ndlela kutshintsha ubude bomda okanye ixesha lesignali yokukhanya kwi-PD sensor. I-SOA amplifier inokufikelela ekusebenzeni okuphezulu kokuva ngokwandisa nokucubungula uphawu lokukhanya.

Ukulinganiswa koxinzelelo lwefayibha yokubona: Ngokudibanisa iifayibha zokubona nezinto ezibuthathaka kuxinzelelo, xa into iphantsi koxinzelelo, kuya kubangela utshintsho ekulahlekelweni kokukhanya ngaphakathi kwefayibha yokubona. I-SOA ingasetyenziselwa ukukhulisa olu phawu lwe-optical olubuthathaka ukuze kufezekiswe umlinganiselo woxinzelelo olubuthathaka kakhulu.

I-SOA ye-semiconductor optical amplifier sisixhobo esibalulekileyo kwicandelo lonxibelelwano lwe-optical fiber kunye nokuva i-optical fiber. Ngokwandisa nokucubungula imiqondiso ye-optical, iphucula ukusebenza kwenkqubo kunye novakalelo lokuva. Ezi zicelo zibalulekile ekufezekiseni unxibelelwano lwe-optical fiber olukhawulezayo, oluzinzileyo noluthembekileyo kunye nokuva i-optical fiber ngokuchanekileyo nangokusebenzayo.
