Kuongororwa kwenheyo ye photoelectric moduleMach Zehnder modulator
Chekutanga, pfungwa huru yeMach Zehnder modulator
Mach-Zehnder modulator imodulator ye optical inoshandiswa kushandura masaini emagetsi kuita masaini e optical. Nheyo yayo yekushanda yakavakirwa pamhedzisiro ye electro-optical, kuburikidza ne electric field kudzora refractive index yechiedza chiri pakati kuti chiwane mwenje modulation, ndeyekupatsanura mwenje we input kuita masaini maviri akaenzana mumatavi maviri e optical emodulator.
Zvinhu zvinoshandiswa mumatavi maviri aya e optical zvinhu zve electro-optical, izvo refractive index inosiyana zvichienderana nehukuru hwechiratidzo chemagetsi chinoshandiswa kunze. Sezvo shanduko ye refractive index yebazi re optical ichizokonzera shanduko yechiratidzo, kana magumo e output emuchina we two branch signal modulator abatanidzwa zvakare, synthesized optical signal ichave chiratidzo chekupindirana nekuchinja kwesimba, izvo zvakaenzana nekushandura shanduko yechiratidzo chemagetsi kuita shanduko yechiratidzo che optical, uye kuona modulation yesimba rechiedza. Muchidimbu, modulator inogona kuona modulation yema side bands akasiyana nekudzora bias voltage yayo.
Chechipiri, basa reMach-Zehnder modulator
Mach-Zehnder modulator inonyanya kushandiswa mukutaurirana kwefiber ye opticalnedzimwe nzvimbo. Mukutaurirana kwe fiber optic, masaini edhijitari anofanirwa kushandurwa kuita masaini e optical kuti atumirwe, uye mamodulators eMachzender anogona kushandura masaini emagetsi kuita masaini e optical. Basa rawo nderekuwana kutumirwa kwechiratidzo nekukurumidza uye kwemhando yepamusoro mumasisitimu ekutaurirana kwe fiber optical.
Modulator yeMach Zehnder inogona zvakare kushandiswa pakutsvaga kwekuyedza mumunda wezvigadzirwa zvemagetsiSemuenzaniso, inogona kushandiswa kugadzira manyuko echiedza akabatana uye kuita mashandiro e-single-photon.
Chechitatu, hunhu hweMach Zehnder modulator
1. Mach Zehnder modulator inogona kushandura masaini emagetsi kuita masaini ekuona kuti iwane kutumira masaini nekukurumidza uye kwemhando yepamusoro.
2. Kana modulator ichishanda, inofanira kushandiswa nezvimwe zvishandiso zvakaita sechiedza, zvinoongorora chiedza, nezvimwewo, kuti igadzire sisitimu yakakwana yekutaurirana nefiber ye optical.
3. Mach Zehnder modulator ine hunhu hwekumhanya nekukurumidza uye kushandiswa kwesimba shoma, izvo zvinogona kusangana nezvinodiwa zvekutaurirana nekukurumidza.
【 Mhedziso】
Modulator yeMach Zehnder imhando yemodulator yemazisoInoshandiswa kushandura chiratidzo chemagetsi kuita chiratidzo chemaziso. Basa rayo nderekusvitsa chiratidzo chemagetsi nekukurumidza uye chemhando yepamusoro munzvimbo dzakadai sekutaurirana kwefiber. Mach zender modulator ine hunhu hwekupindura nekukurumidza uye kushandiswa kwesimba shoma, uye ndeimwe yemidziyo inokosha muhurongwa hwekutaurirana kwefiber.
