Iamplifier ye-semiconductor eyongeziweyo

Iphuculwesemiconductor optical amplifier

Isandisi-lizwi esiphuculweyo sesemiconductor luguqulelo oluphuculweyo lwesandisi-lizwi sesemiconductor (Iamplifier ye-SOA). Yi-amplifier esebenzisa i-semiconductors ukubonelela nge-medium gain. Ukwakhiwa kwayo kufana ne-Fabry-Pero laser diode, kodwa ngokuqhelekileyo ubuso bokugqibela bufakwe ifilimu echasene ne-reflection. Uyilo lwamva nje lubandakanya iifilimu ezichasene ne-reflection kunye ne-waveguides ethambekele kunye nemimandla yefestile, enokunciphisa ukubonakala kobuso besiphelo ukuya ngaphantsi kwe-0.001%. I-high-performance iphuculwe i-optical amplifiers iluncedo ngakumbi xa ukhulisa (i-optical) imiqondiso, njengoko kukho isoyikiso esibi sokulahlekelwa ngumqondiso ngexesha lokuhanjiswa komgama omde. Ekubeni umqondiso we-optical ukhuliswa ngokuthe ngqo, indlela yendabuko yokuyiguqula ibe ngumqondiso wombane ngaphambi kokuba ibe yinto engafunekiyo. Ngoko ke, ukusetyenziswa kweSOAiphucula kakhulu impumelelo yosasazo. Le teknoloji idla ngokusetyenziselwa ukwahlula amandla kunye nembuyekezo yelahleko kwiinethiwekhi zeWDM.

Iimeko zesicelo

Kwiinkqubo zonxibelelwano ze-fiber optical, i-semiconductor optical amplifiers (SOA) ingasetyenziselwa kwiindawo ezininzi zesicelo ukunyusa umgama wokusebenza kunye nokuhanjiswa kwenkqubo yonxibelelwano. Ezi zilandelayo zezinye izicelo eziqhelekileyo zokusebenzisa i-SOA amplifier kwiinkqubo zonxibelelwano lwefiber optical:

Isamplifier: SOAiamplifier yamehloingasetyenziselwa njenge-preamplifier kwisiphelo sokufumana optical kwiinkqubo zonxibelelwano olude olunemicu ye-optical edlula iikhilomitha ezili-100, ukunyusa okanye ukukhulisa amandla emveliso yesignali kwiinkqubo zonxibelelwano ze-fiber optical umgama omde, ngaloo ndlela uhlawulela umgama ongonelanga wokuhanjiswa obangelwa yimveliso ebuthathaka yeempawu ezincinci. Ngaphezu koko, i-SOA ingasetyenziselwa ukuphumeza iteknoloji ye-optical network signal regeneration kwiinkqubo zonxibelelwano ze-fiber optical.

Ukuhlaziywa kwesignali ye-All-optical: Kwinethiwekhi ye-optical networks, njengoko umgama wokudlulisa ukhula, izibonakaliso ze-optical ziya kuhla ngenxa yokunciphisa, ukusabalalisa, ingxolo, i-jitter yexesha kunye ne-crosstalk, njl. Ukuhlaziywa kwesignali ye-All-optical kubhekiselele ekwandiseni kwakhona, ukubunjwa kwakhona kunye nokulungiswa kwexesha. Ukwandiswa okungaphezulu kunokufezekiswa ziamplifiers optical ezifana nesemiconductor optical amplifiers, EDFA kunye neRaman amplifiers (RFA).

Kwiinkqubo ze-fiber optical sensing, i-semiconductor optical amplifiers (Iamplifier ye-SOA) ingasetyenziselwa ukukhulisa imiqondiso ye-optical, ngaloo ndlela iphucula ubuntununtunu kunye nokuchaneka kweenzwa. Ezi zilandelayo zezinye izicelo eziqhelekileyo zokusebenzisa i-SOA kwiinkqubo ze-fiber optical sensing:

I-Optical fiber strain measurement: Lungisa i-fiber optical kwi-into leyo kufuneka ilinganiswe ubunzima bayo. Xa into iphantsi koxinzelelo, ukuguqulwa koxinzelelo kuya kubangela utshintsho oluncinci kubude be-fiber optical, ngaloo ndlela uguqule ubude bexesha okanye ixesha lomqondiso we-optical kwi-sensor ye-PD. I-amplifier ye-SOA inokufezekisa ukusebenza okuphezulu kokuva ngokwandisa kunye nokucwangcisa umqondiso we-optical.

Umlinganiselo woxinzelelo lwe-fiber optical: Ngokudibanisa i-fiber optical kunye nezixhobo ezithintekayo zoxinzelelo, xa into iphantsi koxinzelelo, iya kubangela utshintsho kwilahleko ye-optical ngaphakathi kwe-fiber optical. I-SOA ingasetyenziselwa ukukhulisa olu phawu lubuthathaka ukuphumeza umlinganiselo woxinzelelo olunobuzaza.

I-semiconductor optical amplifier SOA sisixhobo esiphambili kwiinkalo zonxibelelwano lwefiber optical kunye ne-fiber optical sensing. Ngokwandisa kunye nokucubungula imiqondiso ye-optical, iphakamisa ukusebenza kwenkqubo kunye novakalelo lokuva. Ezi zicelo zibalulekile ekufezekiseni unxibelelwano oluhamba ngesantya esiphezulu, oluzinzileyo noluthembekileyo lwefiber optical fibre sensing.
