Zeziphi izicelo zemarikeIiamplifiers ezibonakalayo ze-SOA?
SOAsemiconductor optical amplifiersisixhobo esidibanisa i-PN esisebenzisa i-strain quantum well structure. I-bias yangaphandle yangaphandle iphumela kwi-particle population inversion, kwaye ukukhanya kwangaphandle kukhokelela kwi-radiation evuselelweyo, okubangelwa ukukhulisa umqondiso we-optical. Izinto ezilungileyo: Ixhasa isantya esiphezulu, i-bandwidth ephezulu, ukusetyenziswa kwamandla aphantsi, inzuzo ephezulu, i-miniaturization, kunye nokudibanisa okulula. Ukungalungi: i-modulation ye-cross- gain modulation kunye ne-nonlinear interaction phakathi kweendlela ezahlukeneyo ze-wavelength, i-polarization sensitivity, ukufumana i-saturation. Xa kuthelekiswa ne-EDFA iamplifiers optical (i-erbium-doped fiber amplifiers), ezinye izalathisi zezixhobo zorhwebo zibuthathaka kuneI-EDFA i-optical amplifierskodwa SOAiiamplifiers zamehloziseneempawu i-EDFA Optical amplifiers engenako ukuyibuyisela. Ukuba inokuxhasa i-O-band (1260-1360), i-E-band (1360-1460), i-L-band (1460-1530) yokukhulisa, kwaye ineempawu zexabiso eliphantsi, ubungakanani obuncinci kunye nokudibanisa okulula, kwixesha elitsha leziseko ezingundoqo, i-SOA i-amplifiers optical iya kuba kwinethiwekhi yokufikelela kunye nomda we-fiber ye-fiber yokufikelela, ukufumana i-fiber ye-fiber enkulu, ukufumana i-fiber ye-fiber enkulu, ukufumana i-fiber enkulu ye-fiber.
Ukusetyenziswa kwemarike ye-SOA optical amplifier
Ngokuphuculwa komsebenzi we-SOA optical amplifier njengamandla okukhanya okuphumayo, ukuzuza umqondiso omncinci, ukufumana i-polarization sensitivity kunye ne-index yengxolo, i-SOA amplifier iya kudlala indima ebaluleke kakhulu kunxibelelwano lwenethiwekhi yonke kunye ne-sensor networks. Ukongeza kwi-SOAiiamplifiers zamehloenokuhlangabezana nokwandiswa kwebhendi ye-1310 nm,I-SOA amplifiersinokutshintsha ngokupheleleyo i-EDFA amplifiers kwezinye iindawo zokukhulisa inqanaba elinye le-1550 nm band.
1. Inethiwekhi ye-Carrier optical transmission
Ngokwakhiwa kwenethiwekhi ye-5G, imfuno ye-bandwidth inyuka, kunye ne-100G (4 * 25G CWDM4 / LWDM4) ukuhanjiswa kwesantya esiphezulu kuyafuneka kumda wokufikelela kuthungelwano kunye nothungelwano lommandla we-metropolitan, kunye nomgama wothumelo kumda we-county kunye nelokishi, inethiwekhi yokufikelela kunye nenethiwekhi yendawo ye-metropolitan idla ngokuba yi-5km-. Kwisiseko se-5G kwisikhululo sokuhambisa phambili imeko, kwezinye izikhululo ezikude ezikude, imodyuli yokukhanya.isixhobo se-SOAingasetyenziselwa ukuphucula umda wamandla okukhanya, kwaye uqaphele ukuguqulwa kokukhanya okuphantsi kwesantya sesignali ye-25G yesikhululo sesiseko kwi-1310 nm band kunye ne-1550 nm band. Ekusetyenzisweni kwenethiwekhi yomthwali, i-SOA amplifier inokudibaniswa kwi-ROSA okanye i-TOSA ye-imodyuli yeamplifier yokubona, okanye isixhobo se-SOA esizimeleyo okanyeImodyuli ye-SOA yokubonaingasetyenziselwa ukukhulisa.
2. I-Spectral amplification yokubeka iliso kwinethiwekhi
Okwangoku, kunye nophuhliso olukhawulezayo lweshishini ledatha, imfuno yokubeka iliso kwintengiso yedatha ikhula ngokuthe ngcembe, edla ngokuba kwi-node engundoqo yenethiwekhi yokubeka iliso kwi-spectral, isibonakaliso sihlala sibuthathaka, isidingo sokusebenzisa i-amplifier optical, kunye ne-100G ishishini linobuninzi be-1310 wavelength, inokwandiswa kuphela ngesixhobo se-SOA. Esi sesona sicelo sisetyenziswa kakhulu nesivuthiweyo sokukhulisa i-SOA okwangoku.
3. I-DCI yoqhagamshelwano lweziko ledatha
Ngophuhliso lwedatha enkulu, imfuno yonxibelelwano oluphezulu lwe-bandwidth phakathi kwamaziko edatha iyanda ngokuthe ngcembe. Kwiinkonzo zesantya esiphezulu, isixhobo se-SOA singasetyenziselwa ukukhulisa umqondiso we-optical relay, ukwandisa umda we-link optical power margin kunye nokwandisa umgama wokuhambisa. I-SOA amplifiers ingasetyenziswa kuzo zombini ibhendi ye-1310 kunye ne-1550 yebhendi yenkonzo ye-high-speed service optical amplification. Le marike idla ngokusebenzisa ukuma wedwaI-SOA semiconductor optical amplifiers(izixhobo ezifakwe kwi-rack).
4. Ukusetyenziswa kwe-fiber optic sensing esasazwayo kunye nenkqubo ye-LiDAR
Iimodyuli ze-SOA ze-optical zineempawu ezibalaseleyo zokuphendula rhoqo kunye nomlinganiselo ophezulu wokuphela, kwaye zinokusetyenziswa njengokutshintsha kwe-optical okanye iimodyuli. Ngophuculo oluqhubekayo lwetekhnoloji ye-SOA, iimodyuli ze-AOM zinokutshintshwa kwiindawo ezininzi zokubona i-fiber sensing ukufumana i-laser ye-pulse encinci kunye nomlinganiselo ophezulu wokuphela.
Kwiminyaka yakutshanje, ngophuhliso olukhawulezayo lokuqhuba ngokuzimeleyo kwetrafikhi kunye nolungelelwaniso lwemoto-yendlela, i-LiDAR isetyenziswe ngokubanzi kwicala lemoto kunye nasecaleni kwendlela. Ngenxa ye-miniaturization kunye nenzuzo ephezulu yeImodyuli ye-SOA yeamplifier yokukhanya, ingasetyenziswa kwi-LiDAR ukufumana i-laser yobubanzi obunqamlekileyo kunye nokuphucula amandla aphezulu optical, ngokukodwa i-chip ye-optical Lidar yesizukulwana esilandelayo sobuchwepheshe be-FMCW bendawo, intsimi yesicelo esibanzi se-SOA ye-optical amplifier.
