Kuongorora kwevanhu vanowanzoitika modulator

Pepa iri rinosuma nzira ina yekunyora Izvi zvinosanganisira AOM (Acousto-Optic modulation), EOM (Electro-Optic Modulation), SOM /Soa(Semiconductor mwenje kukwidziridzwa kunozivikanwa se semiconductor modulation), uyeDirect laser modulation. Pakati pavo,Eom, Som ndezvekunze modulation, kana kusarudzika kusekwa.

1. Acousto-Optic Modulator (AOM)

Acousto-Optic modulation chiitiko chemuviri chinoshandisa acousto-optic mhedzisiro yekuisa ruzivo pane yekutakura mutakuri. Paunenge uchimanikidza, iyo yemagetsi chiratidzo (inoshandiswa kusekwa) inotanga kushandiswa kune electro-acoustic transducer, inoshandura chiratidzo chemagetsi mumunda wekupedzisira. Kana iyo Light wave ichipfuura nepakati-optic yepakati, iyo Optical inotakura yakanyorwa uye inova yekuwedzera yakasungirirwa mafungu akatakura ruzivo nekuda kweiyo acousto chiito

2. Electro-Optical Modulator(EOM)

Ma electro-Optical Modulator anoshandisa maElectro-Optical mhedzisiro yeimwe Electro-Optical makristuru emakristuru (Linb03), Gaas makristuru (Gaas (Gaas) uye Lithium Tantalate Makristasi (Litase03). Electro-Optical mhedzisiro ndeyekuti iyo voltage ichishandiswa kune Electro-Optical Crytro-Option Cryistry yeCyral,

Mufananidzo: Typical Kugadziriswa kweEOM Mutyairi Dunhu

3. Semiconductor Optical Modulator / Semiconductor Optical Amplifier (Som / SoA)

Semiconductor Optical Amplifier (SOA) inowanzoshandiswa kune Optical Signal Signal Signal Signal Signal SignalErbium-Dided Filber Amplifier). Semiconductor Optical Modulator (SOM) yakafanana semiconductor Optical Oplifier, uye iyo inoratidza inotarisa kana ichishandiswa seyakaomeswa semanyorerwo mashoma akasiyana neaya anoshandiswa seashandisirwo. Kana ichinge yashandiswa kune Optical Signal chiratidzo, kutyaira kwakasimba ikozvino kunowanzo kupihwa kuSoA kuve nechokwadi chekuti soa inoshanda mudunhu remutsara; Kana ichishandiswa kunongedza Optical pulses, inoenderera mberi yemasaini yemasaini, inoshandisa magetsi emhepo kudzora iyo soa drive razvino, uye wobva wadzora soa yekubuda sosi yekuwedzera / kuwedzeredza. Uchishandisa iyo SOA YEMAHARA uye Attenuation Hunhu, iyi modulation modulation yakaiswa zvishoma nezvishoma kune zvimwe zvekushandisa zvitsva, zvakadai seyekupedzisira fiber kunzwa, Lidar, Oct, Oct kurapa kwekufungidzira uye mamwe minda. Kunyanya kune zvimwe zviitiko izvo zvinoda vhoriyamu yakakwirira, kushandiswa kwesimba uye kutsakatika ratio.

4 Zvinogona kuoneka kuti pane spike kutanga kwekutanga kweiyo pulse, iyo inounzwa nekuzorora kweiyo laser yekutakura. Kana iwe uchida kuwana pulse yeanenge zana picoseconds, unogona kushandisa iyi Spike. Asi kazhinji hatidi kuve neiyi spike.

Kuputa

AOM inokodzera kune Optical Simba Kubuda mune mashoma mavita uye ane frequency shift basa. Eom iri kukurumidza, asi kuoma kwekutyaira kwakakwira uye kutsakatika chiyero chakaderera. Som (soa) ndiyo mhinduro yakakwana yeGHZ kumhanya uye yakakwira kutsakatika chiyero, ine yakaderera simba rekushandisa, miniaturization uye zvimwe zvinhu. Direct laser diode ndiyo yakachipa mhinduro, asi ziva shanduko mune spectral maitiro. Urongwa hwega hwega hwakava nezvakanaka uye zvakashata, uye zvakakosha kuti unzwisise zvinodiwa izvo zvinodiwa pakusarudza chirongwa, uye chenjera nezvakanaka nezvakaipa zvechirongwa chimwe nechimwe, uye sarudza chirongwa chakakodzera kwazvo. Semuenzaniso, mukuparadzira fiber kunzwa, fananidzo yechinyakare ndiyo huru, asi mune mamwe madhiri matsva, mune imwe mhepo mhepo yekugadzira, kuderedza kukura, uye nekuvandudza kukohwa kwekutsakatika, chirongwa cheSOA chinogamuchirwa. Muhurongwa hwekutaurirana, iyo yakadzika mhanyisa system inowanzo tora iyo yakananga yekufambisa chirongwa, uye iyo yakakwira yekumhanya system inowanzo kushandisa iyo Electro-Optic modulation scheme.
