Amagqabantshintshi ngezimo eziqhelekileyo eziqhelekileyo

Amagqabantshintshi ngezimo eziqhelekileyo eziqhelekileyo

Eli phepha lazisa ngeendlela ezine zemodyuli (ukutshintsha i-leser ye-ilplity kwi-nanosecond okanye i-subnanond yexesha lexesha) esetyenziswa rhoqo kwiinkqubo ze-fiber lare. Oku kubandakanya i-AOM (i-ACOTO-OKONOTO-Optic), i-EOM (ELTO Optic), i-SOM /I-soya(i-semiconductor ekhanyayo yokukhanya okwabizwa ngokuba yimodyuli ye-semicondcuction), kwayengqo kwimodareyitha ye-leser. Phakathi kwabo, Am,Ewe, I-smom yeyomdyuli yangaphandle, okanye iModuration engathanga ngqo.

I-1. I-ACOSTO-OKOTCIC MDDULT (AOM)

Imodyuli ye-ACOSOTO-Optic yinkqubo yomzimba esebenzisa i-ACOSTO-OCOTOOTOCK yokulayisha ulwazi kumphathi we-optical. Xa i-modulation, umqondiso wombane (umqondiso wombane) uqale ukwenziwa okokuqala kwi-Electo-Acoustic Transcer, eguqula umqondiso wombane kwintsimi ye-ultrasonic. Xa i-jave yokukhanya idlula kwi-ACosto-Optic Pedium, i-Optical Aptic iphoselwe kwaye iba yimo yemo yemo yemo yemo yemo yemo yemo yemo yemo yemo ye-ACOSOSTO-Optic

2. Imodyuli ye-electro-optical(IOM)

Imodyuli ye-electro-optical yimodyuli esebenzisa imiphumo ye-elektroli ye-elektroniki, njenge-lithium ye-ristal crystals (i-liobate ye-liobate (i-line), i-gaas crystals (i-leta03). Iziphumo ze-electro-Optical kukuba xa i-voltage isetyenziswa kwi-crystal ye-elektrolical, i-Inded ye-Elestal ye-Elecrical iya kutshintsha, ikhokelela kutshintsho lokukhanya kwe-crystal, i-amerting, ubunzulu bophawu lokukhanya luyenzeka.

Umzobo: Uqwalaselo oluqhelekileyo lwesekethe ye-EOM

I-3. I-Semicondo Optical Podulator / I-Semiconductor Optical Amplifi (SOM / SOA)

I-Semicondo Optical Amphaical (SOA) ihlala isetyenziselwa ukwahlula-ntetho, eneengenelo ze-chip, ukusebenzisa amandla aphantsi, inkxaso kuzo zonke iibhendi zemveli njenge-Edfa (I-erbium-doped amplifier). I-semiconductor ye-semiconductor ye-semicondutor (i-SMM) sisixhobo esifanayo ne-semiconductor ye-semiconductor, kodwa isetyenziswa ngendlela esetyenziswa ngayo nge-modulatori yendabuko. Xa isetyenziselwa ukwahlula-thulwa komqondiso, ukuqhuba okuzinzileyo kuhlala kubonelelwa kwi-SOA ukuqinisekisa ukuba i-SOA isebenza kwingingqi yecandelo; Xa isetyenziselwa ukuphuphuma kweepulses, igalelo eliqhubekayo lemiqondiso ye-SOA, isebenzisa iipulses zombane ukulawula i-SOA Drive yangoku, kwaye emva koko ilawule imeko ye-SOA njenge-Amuve / i-Interling. Sebenzisa i-americation ye-SOA kunye neempawu zothintelo, le ndlela yemodyuli ngokuthe ngcembe isetyenziswe kwizicelo ezitsha, ezinje nge-fiber yefibuthe, i-lidar, imvakalelo yonyango kunye namanye amasimi. Ngakumbi kwezinye iimeko ezifuna ivolumu ephezulu, ukusetyenziswa kwamandla kunye nokuphelisa umyinge.

I-4. I-Laser Rodration ikwanokuyilawula isibonakaliso esibonakalayo ngokulawula ngokuthe ngqo i-laser ye-laser, njengoko kubonisiwe kwi-0 Ingabonwa ukuba kukho i-spike ekuqaleni kwepulse, eyaziswa kukuphumla komqhubi we-laser. Ukuba ufuna ukufumana ipuzzle malunga nee-picoseconds ezili-100, ungasebenzisa le spike. Kodwa ngesiqhelo asifuni ukuba ne-spike.

Shwankathela

I-AOM ilungele ukukhutshwa kwamandla okuphezulu kwii-watts ezimbalwa kwaye inomsebenzi weShift of Rift. I-Eom ukhawuleza, kodwa ubunzima obukhulu buphezulu kwaye umyinge wokuphela uphantsi. I-SOM (SOA) sisisombululo esifanelekileyo se-GHZ ngesantya esiphezulu se-GHZ kunye nenqanaba eliphezulu lokusetyenziswa kwamandla, imbiyini kunye nezinye izinto. I-Laser ye-Laser ye-leser sisisombululo sexabiso eliphantsi, kodwa sazi utshintsho kwiimpawu ezibonakalayo. Iskimu ngasinye semodyuli sinezibonelelo zayo ezilungileyo kunye nezinto ezingalunganga, kwaye kubalulekile ukuba siqonde iimfuno zesicelo xa siziqhelanisa neskimu, kwaye sizichaphazelele kwisikimu ngasinye, kwaye sikhethe esona sikimu sifanelekileyo. Umzekelo, kwi-fiber ye-fiber ekwasasazekileyo, i-AOM yesiNtu yeyona nto iphambili, kodwa kwezinye iindlela zenkqubo ye-SOA, ukusetyenziswa kwezikimu ze-SOA zisebenzisa i-AOM yeSistimu, iNkqubo yeNkqubo ye-Idar isebenzisa i-AOM ye-AOOM, kwaye iphucule umyinge we-SOAN. Kwinkqubo yonxibelelwano, inkqubo yesantya esezantsi iyahlala i-Skermes yemodyuli ethe ngqo, kwaye inkqubo yesantya esiphezulu isebenzisa iskimu semodyuli ye-elektrotic.
