TheMach-Zehnder Modulator(MZ Modulator) chishandiso chakakosha chekugadzirisa masaini masaini zvichibva pane yekukanganisa musimboti. Nheyo yekushanda kwayo ndeyotevera: Pabazi rakafanana neY pamagumo ekupinza, chiedza chekupinza chinoparadzaniswa kuva mafungu maviri echiedza uye chinopinda maviri akaenzana optical channels kuti atumire maererano. Iyo optical chiteshi inogadzirwa neye electro-optic zvinhu. Nekutora mukana weiyo photoelectric effect, kana chiratidzo chemagetsi chinoshandiswa kunze chichichinja, iyo refractive index yezvinhu zvayo inogona kuchinjwa, zvichiita kuti pave nekusiyana kwemaoptical nzira misiyano pakati pemitsipa miviri yechiedza inosvika pabazi rakafanana neY pamagumo ekubuda. Kana zvikwangwani zvemaziso mumatanho maviri ekuona zvinosvika pabazi rakafanana neY pamagumo ekubuda, convergence ichaitika. Nekuda kwekunonoka kwechikamu chakasiyana cheaviri masaini masaini, kupindira kunoitika pakati pavo, kushandura chikamu chemutsauko ruzivo rwakatakurwa neaviri masaini masaini muruzivo rwekusimba kwechiratidzo chekubuda. Naizvozvo, basa rekugadzirisa masaini emagetsi pane anotakura anotakura anogona kuwanikwa nekudzora akasiyana ma paramita ekurodha voltage yeMarch-Zehnder modulator.
The basic parameters yeMZ Modulator
Iwo ekutanga ma paramita eMZ Modulator anokanganisa zvakananga mashandiro emodulator mune dzakasiyana siyana dzekushandisa. Pakati pavo, zvakakosha optical parameters uye magetsi emagetsi ndeaya anotevera.
Optical parameters:
(1) Optical bandwidth (3db bandwidth) : Iyo frequency renji kana frequency mhinduro amplitude inoderera ne3db kubva pakukosha kwepamusoro, neyuniti iri Ghz. Optical bandwidth inotaridza frequency renji yechiratidzo kana modulator iri kushanda zvakajairika uye iri parameter yekuyera ruzivo rwekutakura huwandu hweanotakura mutakuri muneelectro-optic modulator.
(2) Extinction ratio: Chiyero chehukuru hwemagetsi emagetsi anobuda ne electro-optic modulator kune mashoma emagetsi emagetsi, nechikamu che dB. Chiyero chekutsakatika iparameter yekuongorora kugona kwe electro-optic switch ye modulator.
(3) Kudzosa kurasikirwa: Chiyero cheyakaratidza chiedza simba pamagumo ekuisamodulatorkune simba rekuisa mwenje, neyuniti yedB. Kurasika kwekudzoka ndiyo parameter inoratidza chiitiko chesimba rinoratidzwa kumashure kune siginecha sosi.
(4) Kurasikirwa kwekupinza: Chiyero chekubuda kwesimba remagetsi kune iyo yekuisa Optical simba remodulator kana yasvika pakunyanya kuburitsa simba, neyuniti iri dB. Kurasikirwa kwekuisa chiratidzo chinoyera kurasikirwa kwemagetsi kunokonzerwa nekuiswa kwenzira yekuona.
(5) Yakanyanya kupinza simba rekuona: Panguva yekushandiswa kwakajairika, iyo MZM Modulator yekuisa magetsi emagetsi inofanira kunge iri shoma pane iyi kukosha kudzivirira kukuvara kwechishandiso, iyo unit iri mW.
(6) Modulation kudzika: Inoreva chiyero cheiyo modulation siginecha amplitude kune inotakura amplitude, inowanzo ratidzwa senge muzana.
Electrical parameters:
Half-wave voltage: Inoreva mutsauko wevoltage unodiwa kuti vhezheni yekutyaira ichinje modulator kubva kumhepo kuenda kune iyo nyika. Iyo inobuda optical simba yeMZM Modulator inosiyana nguva nenguva nekuchinja kwe bias voltage. Kana iyo modulator inobuda inogadzira 180-degree phase musiyano, musiyano mu bias voltage inoenderana nepedyo yepasi poindi uye iyo yepamusoro poindi ndiyo hafu-wave voltage, ine unit yeV. Iyi parameter inotarirwa nezvinhu zvakaita sechinhu, chimiro uye maitiro, uye inherent parameter yeModulator yeMZM.
(2) Maximum DC bias voltage: Panguva yekushandiswa kwakajairika, iyo yekuisa bias voltage yeMZM inofanira kuva shoma pane iyi kukosha kudzivirira kukuvara kwemudziyo. Iyo unit ndeye V. Iyo DC bias voltage inoshandiswa kudzora yakarerekera mamiriro emodulator kuti isangane neyakasiyana modulation zvinodiwa.
(3) Yakanyanya kukosha yechiratidzo cheRF: Panguva yekushandiswa kwakajairwa, iyo RF yemagetsi chiratidzo cheMZM inofanira kunge iri shoma pane iyi kukosha kudzivirira kukuvara kwemudziyo. Chikwata ichi chinonzi V. Chiratidzo cheredhiyo cheredhiyo chiratidzo chemagetsi chinofanirwa kugadziridzwa pane chinotakura chemaziso.
