Nzira dzekuyedza mashandiro e electro-optic modulator

Nzira dzekuyedza dzekuita kwemodulator yemagetsi-optic

1. Matanho ekuyedza voltage yehafu-wave yemodulator yesimba remagetsi-optic

Tichitora voltage yehafu-wave paRF terminal semuenzaniso, manyuko echiratidzo, mudziyo uri kuyedzwa uye oscilloscope zvakabatana kuburikidza nemudziyo une nzira nhatu. Paunenge uchiyedza voltage yehafu-wave paBias terminal, isanganise zvichienderana nemutsetse une madotted.

b. Batidza chiedza chinobuda uye chinobuda chiratidzo, woisa chiratidzo chewave yesawtooth (nguva yekuyedza yakajairika i1KHz) kumudziyo uri kuyedzwa. Chiratidzo chewave yesawtooth Vpp chinofanira kunge chakakura kupfuura voltage yehafu yemafungu kaviri.

c. Batidza oscilloscope;

d. Chiratidzo chekubuda kwe detector chiratidzo che cosine. Nyora kukosha kwe sawtooth wave voltage V1 ne V2 zvinoenderana ne peaks dziri pedyo uye troughs dzechiratidzo ichi. e. Verenga voltage yehafu-wave zvichienderana neFormula (3).

2. Matanho ekuedza kuona kana paine voltage yehafu yemafungumodulator yechikamu chemagetsi-optic

Mushure mekubatanidza sisitimu yekuedza, musiyano wenzira yemaziso pakati pemaoko maviri anoumba chimiro cheinterferometer che optical unofanira kunge uri mukati mehurefu hwekubatana. Chitubu chesignal neRF terminal yechishandiso chiri kuyedzwa pamwe nechiteshi 1 cheoscilloscope zvakabatana kuburikidza nechishandiso chine nzira nhatu. Mushure mekubatanidza sisitimu yekuedza, musiyano wenzira yemaziso pakati pemaoko maviri anoumba chimiro cheinterferometer che optical unofanira kunge uri mukati mehurefu hwekubatana. Chitubu chesignal neRF terminal yechishandiso chiri kuyedzwa pamwe nechiteshi 1 cheoscilloscope zvakabatana kuburikidza nechishandiso chine nzira nhatu, uye pombi yekupinda yeoscilloscope inogadziriswa kune mamiriro e-impedance ane high-impedance.

b. Batidza laser nekwakabva chiratidzo, woisa chiratidzo chewave resawtooth chine frequency yakati (yakajairika 50KHz) kumudziyo uri kuyedzwa. Chiratidzo chekubuda che detector chiratidzo che cosine. Vpp yechiratidzo chewave re sawtooth inofanira kunge yakakura kupfuura kaviri voltage yehafu-wave, asi isingapfuure huwandu hwe input voltage hwakatarwa ne modulator, kuitira kuti chiratidzo chewave resawtooth che detector chiratidze kanenge kutenderera kamwe chete.

c. Nyora kukosha kwevoltage yesawtooth wave V1 neV2 zvinoenderana nemakomo ari pedyo nepamusana pechiratidzo checosine;

d. Verenga voltage yehafu-wave zvichienderana neFormula (3).

3. Kurasikirwa kwekuisa kwema electro-optic modulators

Matanho ekuyedza

Mushure mekubatanidza chiedza ne polarizer, vhura chiedza uye edza simba re optical Pi remuchina uri kuyedzwa uchishandisa optical power meter.

b. Batanidza mudziyo uri kuyedzwa kune sisitimu yekuyedza, uye batanidza materminal ekubuda kwesimba remagetsi rinodzorwa nepini 1 (GND) uye 2 (Bias) yemodulator(kune mamwe ma modulators, pini 1 ye modulator inofanirawo kubatanidzwa kune housing).

c. Gadzirisa voltage inobuda yemagetsi anodzorwa uye edza kuverenga kwakanyanya kwemita yemagetsi e optical sePout.

d. Kana mudziyo uri kuyedzwa uri phase modulator, hapana chikonzero chekuwedzera voltage stabilizing power supply. Iyo Pout inogona kuverengwa zvakananga kubva pa optical power meter.

e. Verenga kurasikirwa kwekuisa zvichienderana neForamu (1).

Zvekungwaririra

a. Kupinza kwe optical kwe electro-optic modulator hakufanirwe kudarika kukosha kwe calibration pa test report; zvikasadaro,Modulator yeEOzvichakuvara.

b. RF input ye electro-optic modulator haifanirwe kudarika kukosha kwe calibration pa test sheet; zvikasadaro, EO modulator ichakuvadzwa.

c. Pakugadzika interferometer, pane zvinodiwa zvakanyanya zvekushandisa. Kuzununguka kwezvakatipoteredza uye kuzununguka kwefiber ye optical zvinogona kukanganisa mhedzisiro yebvunzo.
