Njira yogwiritsira ntchitosemiconductor kuwala amplifier(SOA) ndi motere:
SOA semiconductor optical amplifier imagwiritsidwa ntchito kwambiri m'mbali zonse za moyo. Limodzi mwa mafakitale ofunikira kwambiri ndi kulumikizana kwa mafoni, komwe kumayamikiridwa kwambiri pakuwongolera ndi kusinthana kwa maukonde.Chowonjezera cha kuwala cha semiconductor cha SOAimagwiritsidwanso ntchito kukulitsa kapena kukulitsa kutulutsa kwa chizindikiro cha kulumikizana kwa ulusi wautali wa optical ndipo ndi chida chofunikira kwambiri chokulitsa kuwala.
Njira zoyambira zogwiritsira ntchito
Sankhani yoyeneraChokulitsa kuwala cha SOA: Kutengera ndi zochitika ndi zofunikira zinazake zogwiritsira ntchito, sankhani amplifier ya SOA yokhala ndi magawo oyenera monga kutalika kwa nthawi yogwira ntchito, kuchuluka kwa mphamvu, mphamvu yotulutsa yokhuta, ndi kuchuluka kwa phokoso. Mwachitsanzo, mu machitidwe olumikizirana ndi kuwala, ngati kukulitsa chizindikiro kuyenera kuchitika mu gulu la 1550nm, amplifier ya SOA yokhala ndi kutalika kwa nthawi yogwira ntchito pafupi ndi izi iyenera kusankhidwa.
Lumikizani njira yowunikira: Lumikizani mbali yolowera ya SOA semiconductor optical amplifier ku gwero la chizindikiro cha kuwala lomwe likufunika kukulitsidwa, ndikulumikiza mbali yotulukira ku njira yotsatira ya kuwala kapena chipangizo chowunikira. Mukalumikiza, samalani ndi momwe ulusi wowunikira umagwirira ntchito ndipo yesani kuchepetsa kutayika kwa kuwala. Zipangizo monga zolumikizira za fiber optic ndi zosiyanitsa kuwala zingagwiritsidwe ntchito kukonza kulumikizana kwa njira yowunikira.
Konzani mphamvu ya bias: Yang'anirani phindu la amplifier ya SOA posintha mphamvu yake ya bias. Kawirikawiri, mphamvu ya bias ikakhala yayikulu, phindu limakwera, koma nthawi yomweyo, zingayambitse kuwonjezeka kwa phokoso ndi kusintha kwa mphamvu yotulutsa yokhuta. Mtengo woyenera wa bias current uyenera kupezeka kutengera zofunikira zenizeni ndi magawo a magwiridwe antchito aChokulitsa cha SOA.
Kuwunika ndi kusintha: Pakugwiritsa ntchito, ndikofunikira kuyang'anira mphamvu yotulutsa, kuchuluka, phokoso ndi magawo ena a SOA nthawi yeniyeni. Kutengera zotsatira zakuwunika, mphamvu ya bias ndi magawo ena ayenera kusinthidwa kuti zitsimikizire magwiridwe antchito okhazikika komanso mtundu wa chizindikiro cha SOA semiconductor optical amplifier.
Kugwiritsa ntchito m'njira zosiyanasiyana
Njira yolumikizirana ndi kuwala
Mphamvu yokweza: Chizindikiro cha kuwala chisanatumizidwe, chokweza kuwala cha SOA semiconductor chimayikidwa kumapeto kwa chotumizira kuti chiwonjezere mphamvu ya chizindikiro cha kuwala ndikukulitsa mtunda wotumizira wa dongosolo. Mwachitsanzo, polankhulana ndi ulusi wautali, kukulitsa zizindikiro za kuwala kudzera mu SOA semiconductor optical amplifier kungachepetse chiwerengero cha malo otumizirana mauthenga.
Chokulitsa mzere: Mu mizere yotumizira mauthenga a kuwala, SOA imayikidwa nthawi zina kuti ibwezeretse kutayika komwe kumachitika chifukwa cha kuchepa kwa ulusi ndi zolumikizira, kuonetsetsa kuti zizindikiro za kuwala zimakhala bwino panthawi yotumizira mauthenga akutali.
Choyankhira mawu: Pamapeto pake, SOA imayikidwa patsogolo pa choyankhira mawu ngati choyankhira mawu kuti chiwonjezere kukhudzidwa kwa choyankhira mawu ndikuwonjezera kuthekera kwake kuzindikira zizindikiro zofooka za kuwala.
2. Dongosolo lozindikira kuwala
Mu demodulator ya fiber Bragg grating (FBG), SOA imakweza chizindikiro cha kuwala kupita ku FBG, imawongolera komwe chizindikiro cha kuwala chikupita kudzera mu circulator, ndipo imamva kusintha kwa kutalika kwa nthawi kapena nthawi ya chizindikiro cha kuwala chomwe chimayambitsidwa ndi kutentha kapena kusinthasintha kwa mphamvu. Mu kuzindikira ndi kusinthasintha kwa kuwala (LiDAR), amplifier ya SOA yopepuka, ikagwiritsidwa ntchito limodzi ndi ma laser a DFB, imatha kupereka mphamvu yayikulu yotulutsa kuti izindikire mtunda wautali.
3. Kutembenuka kwa kutalika kwa mafunde
Kusintha kwa mafunde kumachitika pogwiritsa ntchito zotsatira zosalunjika monga cross-gain modulation (XGM), cross-phase modulation (XPM), ndi four-wave mixing (FWM) ya SOA optical amplifier. Mwachitsanzo, mu XGM, kuwala kofooka kozindikira mafunde kosalekeza ndi kuwala kwamphamvu kwa pampu zimalowetsedwa nthawi imodzi mu SOA optical amplifier. Pampu imasinthidwa ndikugwiritsidwa ntchito ku kuwala kozindikira kudzera mu XGM kuti ikwaniritse kusintha kwa mafunde.
4. Jenereta ya kuwala kwa pulse
Mu maulumikizidwe olumikizirana a OTDM a wavelength division multiplexing, ma laser a fiber ring okhala ndi mode-locked okhala ndi SOA optical amplifier amagwiritsidwa ntchito popanga ma pulse osinthika a wavelength. Mwa kusintha magawo monga bias current ya SOA amplifier ndi modulation frequency ya laser, kutulutsa kwa ma optical pulses a ma wavelength osiyanasiyana ndi ma repetition frequency kumatha kuchitika.
5. Kubwezeretsa kwa wotchi yowala
Mu dongosolo la OTDM, wotchiyo imatengedwa kuchokera ku zizindikiro zowunikira mwachangu kudzera mu ma loops otsekedwa ndi gawo ndi ma switch optical omwe amagwiritsidwa ntchito kutengera amplifier ya SOA. Chizindikiro cha data cha OTDM chimalumikizidwa ndi galasi la ring la SOA. Dongosolo la optical control pulse lomwe limapangidwa ndi laser yosinthika yotsekedwa ndi mode limayendetsa galasi la ring. Chizindikiro chotulutsa cha galasi la ring chimazindikirika ndi photodiode. Ma frequency a oscillator olamulidwa ndi voltage (VCO) amatsekedwa pa frequency yoyambira ya chizindikiro cha data cholowera kudzera mu gawo lotsekedwa, motero zimapangitsa kuti wotchi ya optical ibwezeretsedwe.
