Yiziphi izinhlelo zokusebenza zemaketheAma-amplifiers optical we-SOA?

I-SOAi-semiconductor optical amplifieriyithuluzi lokuhlanganisa le-PN elisebenzisa isakhiwo somthombo we-strain quantum. Ukuchema okuya phambili kwangaphandle kubangela ukuguqulwa kwezinhlayiyana zabantu, futhi ukukhanya kwangaphandle kuholela emisebeni evuselelwe, okuholela ekukhuliseni isignali ye-optical. Izinzuzo: Isekela isivinini esikhulu, umkhawulokudonsa ophezulu, ukusetshenziswa kwamandla okuphansi, inzuzo ephezulu, i-miniaturization, nokuhlanganiswa okulula. Ukungalungi: ukuguquguquka kwenzuzo enqamulayo kanye nokusebenzisana okungaqondile phakathi kwamashaneli amaza amaza ahlukene, ukuzwela kwe-polarization, ukuthola ukugcwaliswa kwesikhala. Uma kuqhathaniswa ne-EDFA optical amplifiers (i-erbium-doped fiber amplifiers), ezinye izinkomba zemishini yokuthengisa zibuthakathaka kuneAma-amplifiers optical e-EDFAkodwa SOAama-amplifiers opticalzisenezici i-EDFA Optical amplifiers engeke ikwazi ukuzishintsha. Uma ingakwazi ukusekela i-O-band (1260-1360), i-E-band (1360-1460), i-L-band (1460-1530) yokukhulisa, futhi inezici zezindleko eziphansi, usayizi omncane nokuhlanganiswa okulula, enkathini entsha yengqalasizinda, ama-amplifiers optical we-SOA azoba kunethiwekhi yokufinyelela kanye nomkhawulo we-sensing-fiber yesicelo ukuze uthole i-sensing-fiber field ukuze uthole i-fiber enkulu.

Ukusetshenziswa kwemakethe kwe-SOA optical amplifier

Ngokuthuthukiswa kokusebenza kwe-SOA optical amplifier njengamandla okukhipha optical, ukuzuza kwesignali encane, ukuthola ukuzwela kwe-polarization kanye nenkomba yomsindo, i-SOA amplifier izodlala indima ebaluleke kakhulu ekuxhumaneni kwenethiwekhi yonke ye-optical kanye namanethiwekhi wezinzwa. Ngaphezu kwe-SOAama-amplifiers opticalengahlangabezana nokukhuliswa kwebhendi engu-1310 nm,Ama-amplifiers e-SOAingashintsha ngokuphelele ama-amplifiers e-EDFA kwezinye izinkambu zokukhulisa isigaba esisodwa zebhendi engu-1550 nm.

1. Inethiwekhi yenkampani yenethiwekhi yokudlulisa amehlo

Ngokwakhiwa kwenethiwekhi ye-5G, isidingo somkhawulokudonsa siyakhuphuka, futhi ukudluliselwa kwesivinini esikhulu kwe-100G (4*25G CWDM4/LWDM4) kuyadingeka emaphethelweni enethiwekhi yokufinyelela kanye nenethiwekhi yendawo yedolobha elikhulu, futhi ibanga lokudlulisela emaphethelweni okudluliselwa kwesifunda nelokishi, inethiwekhi yokufinyelela kanye nenethiwekhi yendawo yedolobha elikhulu ngokuvamile iba ngu-50km-. Esimeni sokudlulisela phambili esiteshini se-5G, kwezinye iziteshi ezikude, i-optical modular.Idivayisi ye-SOAingasetshenziswa ukuthuthukisa imajini yamandla okukhanya, futhi ibone ukuguqulwa kokukhanya okuphansi kwezinga lesignali ye-25G yesiteshi sesisekelo kubhendi ye-1310 nm kanye ne-1550 nm band. Ekusetshenzisweni kwenethiwekhi yenkampani yenethiwekhi, i-SOA amplifier ingahlanganiswa ne-ROSA noma i-TOSA ye-i-optical amplifier module, noma idivayisi ezimele ye-SOA nomaI-SOA optical moduleingasetshenziselwa ukukhulisa.

2. Ukukhulisa i-Spectral yokuqapha inethiwekhi

Njengamanje, ngokuthuthuka okusheshayo kwebhizinisi ledatha, isidingo sokuqapha ukusakazwa kwedatha emakethe sikhula kancane kancane, okuvame ukuba ku-node yenethiwekhi eyinhloko yokuqapha kwe-spectral, isignali ngokuvamile ibuthakathaka, isidingo sokusebenzisa i-amplifier optical, futhi ibhizinisi le-100G linobuningi be-wavelength ye-1310, lingakhuliswa kuphela ngedivayisi ye-SOA. Lokhu futhi ukusetshenziswa okusetshenziswe kakhulu futhi okuvuthiwe kwe-SOA amplification okwamanje.

3. I-DCI yokuxhumanisa isikhungo sedatha

Ngokuthuthukiswa kwedatha enkulu, isidingo sokuxhuma komkhawulokudonsa ophezulu phakathi kwezikhungo zedatha sikhula kancane kancane. Ngezinsizakalo zesivinini esikhulu, idivaysi ye-SOA ingasetshenziselwa ukukhulisa isignali yokudlulisa amehlo, ikhulise i-link optical power margin nokwelula ibanga lokudlulisela. Ama-amplifiers e-SOA angasetshenziswa kuwo womabili ibhendi engu-1310 kanye ne-1550 band yokukhulisa isignali yesevisi yesivinini esiphezulu. Le makethe ivamise ukusebenzisa ukuzimelaI-SOA semiconductor optical amplifiers(imishini yokubeka i-rack).

4. Ukusetshenziswa kokusatshalaliswa kwe-fiber optic sensing kanye nesistimu ye-LiDAR

Amamojula we-SOA optical anezici ezinhle kakhulu zokuphendula imvamisa kanye nesilinganiso sokuqothulwa okuphezulu, futhi angasetshenziswa njengama-switch optical noma ama-modulators. Ngokuthuthukiswa okuqhubekayo kobuchwepheshe be-SOA, ama-modulators e-AOM angashintshwa ezimweni eziningi ze-optical fibre sensing ukuze athole i-laser pulse ewumngcingo enesilinganiso sokuqedwa okuphezulu.

Eminyakeni yamuva nje, ngokuthuthuka okusheshayo kobuhlakani bokushayela okuzenzakalelayo kwethrafikhi kanye nokuxhumana kwezimoto nomgwaqo, i-LiDAR isetshenziswe kabanzi kuwo womabili amandla aseceleni kwezimoto nasemgwaqweni. Ngenxa ye-miniaturization kanye nenzuzo ephezulu yeI-SOA optical amplifier module, ingasetshenziswa ku-LiDAR ukuze ithole i-laser yobubanzi obuncane bomugqa futhi ithuthukise amandla aphezulu optical, ikakhulukazi i-optical chip Lidar yesizukulwane esilandelayo sobuchwepheshe be-FMCW bendawo, okuyinkambu yohlelo lokusebenza olubanzi lwe-SOA optical amplifier yesikhathi esizayo.
