Kuti usangane nekuwedzera kwevanhu kudiwa kweruzivo, huwandu hwekutapurirana hwekutakura fiber kutaurirana masisitimu ari kuwedzera zuva nezuva. Iyo yeramangwana Rekutaurirana Network ichave inovandudza kune iyo Optical Fiber Kukurukurirana network ne Ultra-yakanyanya-yakakura, Ultra-refu, uye Ultra-yakakwira spectrum inoshanda. Transmitter inokosheswa. Iyo yakakwira-yekumhanyisa smurity signmitter inonyanya kuumbwa yeiyo laser iyo inounza mutakuri wekutakura, uye yakaomesesa gadziriso yekugadzira chishandiso, uye yakakwira Electro-Optical Modulator inotakura mutakuri. Kuenzaniswa nemamwe marudzi emamwe modulators, lithium niobate electro-Optical modulators ane zvakanakira nguva zhinji, kuumbwa kwechiyero, etcomputer.
Iyo hafu-wave voltage inonyanya kutsoropodza paramende yeiyo Electro-Optic Modulator. Iyo inomiririra shanduko mune basas voltage inoenderana neyekuburitsa mwenje weiyo Electro-Optic modulator kubva kune zvishoma kusvika kune iyo yepamusoro. Iyo inosarudza iyo Electro-Optic Modulator kusvika pamwero mukuru. Maitiro Ekunyatsoziva uye Kurumidza Kuyera hafu-Wave Voltage yeElectro-Optic Modulator yakakosha kukosha kwekuita basa remushini uye kugadzirisa kushanda kwechigadzirwa. Iyo hafu-wave voltage yeiyo Electro-Optic modulator inosanganisira DC (hafu-wave
voltage uye radiofrequency) hafu-wave voltage. Basa rekutamisa reElectro-Optic Modulator ruri seinotevera:
Pakati pavo pane iyo yekubuditsa simba simba reElectro-Optic Modulator;
Ndiyo nzvimbo yekuisa yechokwadi yeModulator;
Ndiko kurasikirwa kwekuisa kweElectro-Optic Modulator;
Nzira dziripo dzekuyera hafu-masaya voltage zvinosanganisira zvakanyanyisa kukosha kwechizvarwa uye chinogona kuyera nzira dzazvino
Tafura 1 Kuenzanisa kwehafu-mafu-wave voltage bvunzo nzira
| Yakanyanya kukosha nzira | Frequency kupokana nzira | |
| Laboratory Equipment | Laser Simba Supply Mirality modulator pasi pekuedzwa Kugadziriswa DC Power Supply】 15V Optical Simba Meter | Laser mwenje tsime Mirality modulator pasi pekuedzwa Inogadziriswa DC Simba Supply Oscilloscope Signal Source (Dc bias) |

Inoshanda seinotevera:
(1) Yakanyanya kukosha nzira
Iyo yakanyanya kukosha nzira iyo nzira inoshandiswa kuyera iyo DC hafu-wave voltage yeiyo Electro-Optic Modulator. Kutanga, pasina chiratidzo chekutamanikidza, iyo yekushongedza yemagetsi-Optic moduas yekukwenenzvera uye yekushambadzira nzvimbo yekukwana Pakupedzisira, musiyano uripo pakati peiyi miviri voltage tsika ndiyo hafu-wave vrtage vπ = vmax-vmax-vmax-vmafmin yeiyo Electro-Optic Modulator.
(2) kuwanda kwenzira nzira
Yakanga ichishandisa nzira yekudzikisira kuyera nzira yekuyera iyo RF hafu-wave voltage yeiyo Electro-Optic Modulator. Wedzera iyo dc bias computer uye ac modulation chiratidzo kune iyo Electro-Optic modulator panguva imwechete yekugadzirisa iyo dc voltage kana iyo yekubuda pachena kushandurwa kune yakanyanya kukosha kana kushoma kukosha. Panguva imwecheteyo, uye inogona kucherechedzwa pane dial-trace oscesloscope iyo iyo inoburitsa chiratidzo chakaburitswa chinoita senge freathing kupokana kukanganisa kukanganisa. Musiyano chete weDCT Voltage inoenderana neyakafambidzana neyakawirwa neyakafurova kuputsa kukanganisa ndeye RF hafu-wave voltage yeiyo Electro-Optic modulator.
Pfupiso: Zvese zvakanyanyisa kukosha nzira uye nzira yekudzikisira kunogona kuyera iyo hafu-wave yekuyera nguva, uye nguva yekuyera kwenguva refu ichave nekuda kwesimba rekunze reLaser rinochinja uye rinokonzeresa zvikanganiso. Iyo yakanyanya kukosha nzira inoda kuongorora iyo dc bias ine danho diki kukosha uye rekodha iyo yekubuditsa Optic simba reModulator panguva imwe chete yekuwana imwe chete yakawedzera DC hafu yeCCOL-WALCE kukosha.
Iyo yekudzikisira nzira nzira yekutsanangura hafu-wave voltage nekuona iyo frequency kuputsa waveform. Kana iyo yekuisa bias voltage inosvika kune imwe kukosha, frequency yekuwedzera kukanganisa kunoitika, uye kushushikana kwekuwedzera hakuonekwe zvakanyanya. Hazvisi nyore kuchengeta neziso rakashama. Nenzira iyi, ichaita kuti zvikanganiso zvakakura zvakanyanya, uye izvo zvinoyera hafu yeRF-infukudza voltage yeiyo Electro-Optic modulator.
