Momwe mungagwiritsire ntchitoEO modulator
Mutalandira modulator ya EO ndikutsegula phukusi, chonde valani magolovesi a electrostatic / wristbands mukakhudza mbali yachitsulo chubu chipolopolo cha chipangizocho. Gwiritsani ntchito ma tweezers kuti muchotse madoko olowera / zotulutsa za chipangizocho poyambira bokosilo, ndiyeno chotsani mbali yayikulu ya chowongolera pamipopo ya siponji. Kenako gwirani thupi lalikulu la EO modulator m'dzanja limodzi ndikukokerani cholumikizira cholumikizira / chotulutsa cha modulator ndi china.
Kukonzekera ndi kuyang'anitsitsa musanagwiritse ntchito
a. Onani kuti palibe kuwonongeka kwa chinthucho, pamwamba pa module ndi manja a fiber optical.
b. Onetsetsani kuti chizindikirocho chilibe dothi ndipo zizindikiro zosindikizira za silika ndi zomveka.
c. Flange yamagetsi sinawonongeke ndipo ma pini a ma elekitirodi onse ndi osasunthika.
d. Gwiritsani ntchito chojambulira chakumapeto kwa ulusi kuti muwone ngati ulusi wa mbali zonse ziwiri uli woyera.
1. Njira zogwiritsira ntchitomphamvu modulator
a. Yang'anani ngati mbali zomaliza za ulusi wolowetsa / zotulutsa za chosinthira mwamphamvu ndizoyera. Ngati pali madontho, chonde pukutani ndi mowa.
b. The intensity modulator ndikulowetsa polarization-kusunga. Ndibwino kuti mugwiritse ntchito polarization-kusunga gwero lounikira pamene likugwiritsidwa ntchito (kutalika kwa gwero la kuwala kumadalira kutalika kwa mawonekedwe a modulator), ndipo mphamvu ya kuwala kwa gwero la kuwala makamaka 10dBm.
Mukamagwiritsa ntchito mphamvu yamagetsi, gwirizanitsani magetsi a GND ku pini 1 ya modulator, ndi malo abwino opangira magetsi kuti aphimbe 2. Pin 3/4 ndi cathode ndi anode ya PD mkati mwa modulator. Ngati mukufuna kuigwiritsa ntchito, chonde gwiritsani ntchito PD iyi ndi dera logulitsira kumapeto kumbuyo, ndipo PD iyi ingagwiritsidwe ntchito popanda kugwiritsa ntchito magetsi (ngati modulator ilibe PD yamkati, pini 3/4 ndi NC, pini yoyimitsidwa).
d. Zida zamphamvu modulator ndi lithiamu niobate. Munda wamagetsi ukagwiritsidwa ntchito, index refractive ya kristalo idzasintha. Chifukwa chake, voteji ikagwiritsidwa ntchito pa modulator, kutayika kwa kuyika kwa modulator kumasiyana ndi mphamvu yomwe imagwiritsidwa ntchito. Ogwiritsa ntchito amatha kuwongolera modulator pamalo ena ogwiritsira ntchito malinga ndi momwe amagwiritsira ntchito.
Kusamalitsa
a. Kuyika kwa kuwala kwa modulator sikuyenera kupitirira mtengo wa calibration pa pepala loyesera; apo ayi, modulator idzawonongeka.
b. Kuyika kwa RF kwa modulator sikuyenera kupitirira mtengo wovomerezeka pa pepala loyesera; apo ayi, modulator idzawonongeka.
c. Mpweya wowonjezera wa pini ya voltage bias voltage ndi ≤± 15V
2. Njira zogwiritsira ntchitogawo modulator
a. Yang'anani ngati mbali zomaliza za ulusi wolowetsa / zotulutsa za chosinthira mwamphamvu ndizoyera. Ngati pali madontho, chonde pukutani ndi mowa.
b. The gawo modulator ndi polarization-kusunga zolowetsa. Ndibwino kuti mugwiritse ntchito polarization-kusunga gwero lounikira pamene likugwiritsidwa ntchito (kutalika kwa gwero la kuwala kumadalira kutalika kwa mawonekedwe a modulator), ndipo mphamvu ya kuwala kwa gwero la kuwala makamaka ndi 10dBm.
c. Mukamagwiritsa ntchito chosinthira gawo, lumikizani chizindikiro cha RF ku doko lolowera la RF la modulator.
d. Gawo la modulator limatha kugwira ntchito pambuyo powonjezera ma frequency a wailesi, kumaliza gawoloelectro-optic modulator. Kuwala kosinthidwa sikungadziwike mwachindunji ndi photodetector ngati siginecha ya ma radio frequency modulated. Kawirikawiri, interferometer iyenera kukhazikitsidwa, ndipo chizindikiro cha maulendo a wailesi chimatha kudziwika ndi photodetector pambuyo posokoneza.
Kusamalitsa
a. Kuyika kwa kuwala kwa EO modulator sikuyenera kupitirira mtengo wa calibration pa pepala loyesera; apo ayi, modulator idzawonongeka.
b. Kuyika kwa RF kwa EO modulator sikuyenera kupitirira mtengo wovomerezeka pa pepala loyesera; apo ayi, modulator idzawonongeka.
c. Mukakhazikitsa interferometer, pali zofunika kwambiri pa malo ogwiritsira ntchito. Kugwedezeka kwa chilengedwe ndi kugwedezeka kwa kuwala kwa fiber kungakhudze zotsatira za mayeso.
