Momwe mungagwiritsire ntchitoEO modulator
Mukalandira EO modulator ndikutsegula phukusi, chonde valani magolovesi/ma wristband amagetsi mukakhudza gawo la chipolopolo cha chubu chachitsulo cha chipangizocho. Gwiritsani ntchito ma tweezers kuti muchotse ma port optical input/output ports a chipangizocho m'mipata ya bokosilo, kenako chotsani thupi lalikulu la modulator m'mipata ya siponji. Kenako gwirani thupi lalikulu la EO modulator ndi dzanja limodzi ndikukoka optical input/output port ya modulator ndi dzanja lina.
Kukonzekera ndi kuwunika musanagwiritse ntchito
a. Onetsetsani kuti palibe kuwonongeka kwa pamwamba pa chinthucho, pamwamba pa module ndi sleeve ya ulusi wowala.
b. Onetsetsani kuti chizindikirocho chilibe dothi ndipo zizindikiro zosindikizira za silk-screen zili bwino.
c. Flange yamagetsi siiwonongeka ndipo ma electrode pini onse ndi abwino.
d. Gwiritsani ntchito chowunikira nkhope ya ulusi wa kuwala kuti muwone ngati ulusi wa kuwala uli kumapeto onse awiri ndi woyera.
1. Njira zogwiritsira ntchitomodulator ya mphamvu
a. Onetsetsani ngati mbali za kumapeto kwa ulusi wa kuwala wolowera/wotulutsa wa intensity modulator zili zoyera. Ngati pali madontho, chonde apukuteni ndi mowa.
b. Modulator ya mphamvu ndi njira yosungira polarization. Ndikofunikira kugwiritsa ntchito gwero la kuwala losunga polarization mukamagwiritsa ntchito (mafunde a gwero la kuwala amadalira mafunde oyenera a modulator), ndipo mphamvu ya kuwala ya gwero la kuwala ndi 10dBm.
Mukagwiritsa ntchito strength modulator, lumikizani power supply GND ku pin 1 ya modulator, ndi positive terminal ya power supply ku pin 2. Pin 3/4 ndi cathode ndi anode ya PD mkati mwa modulator. Ngati mukufuna kuigwiritsa ntchito, chonde gwiritsani ntchito PD iyi ndi acquisition circuit kumapeto, ndipo PD iyi ingagwiritsidwe ntchito popanda kugwiritsa ntchito voltage (ngati modulator ilibe PD yamkati, pin 3/4 ndi NC, suspended pin).
d. Zinthu zomwe zili mu intensity modulator ndi lithiamu niobate. Pamene magetsi agwiritsidwa ntchito, refractive index ya kristalo imasintha. Chifukwa chake, magetsi akagwiritsidwa ntchito pa modulator, kutayika kwa insertion ya modulator kumasiyana malinga ndi voltage yomwe yagwiritsidwa ntchito. Ogwiritsa ntchito amatha kuwongolera modulator pamalo enaake ogwirira ntchito malinga ndi momwe amagwiritsidwira ntchito.
Kusamalitsa
a. Cholowera cha kuwala cha modulator sichiyenera kupitirira mtengo wowerengera pa pepala loyesera; apo ayi, modulator idzawonongeka.
b. Kulowetsa kwa RF kwa modulator sikuyenera kupitirira mtengo woyesedwa pa pepala loyesera; apo ayi, modulator idzawonongeka.
c. Voltage yowonjezera ya pini ya voliyumu ya modulator ndi ≤±15V
2. Njira zogwiritsira ntchitomodulator ya gawo
a. Onetsetsani ngati mbali za kumapeto kwa ulusi wa kuwala wolowera/wotulutsa wa intensity modulator zili zoyera. Ngati pali madontho, chonde apukuteni ndi mowa.
b. Phase modulator ndi njira yolumikizira polarization. Ndikofunikira kugwiritsa ntchito polarization-safetaining light source mukamagwiritsa ntchito (mafunde a kuwala kwa gwero la kuwala amadalira mafunde oyenera a modulator), ndipo mphamvu ya kuwala kwa gwero la kuwala ndi 10dBm.
c. Mukagwiritsa ntchito phase modulator, lumikizani chizindikiro cha RF ku doko lolowera la RF la modulator.
d. Gawo lowongolera limatha kugwira ntchito pambuyo powonjezera chizindikiro cha ma frequency a wailesi, ndikumaliza gawolomodulator yamagetsiKuwala kosinthidwa sikungathe kuzindikirika mwachindunji ndi chowunikira zithunzi monga chizindikiro cha mafunde chosinthidwa. Nthawi zambiri, interferometer imafunika kukhazikitsidwa, ndipo chizindikiro cha mafunde chimatha kuzindikirika ndi chowunikira zithunzi pambuyo poti chasokonezedwa.
Kusamalitsa
a. Kulowetsa kwa kuwala kwa EO modulator sikuyenera kupitirira mtengo wowerengera pa pepala loyesera; apo ayi, modulator idzawonongeka.
b. Kulowetsa kwa RF kwa EO modulator sikuyenera kupitirira mtengo woyesedwa pa pepala loyesera; apo ayi, modulator idzawonongeka.
c. Mukakhazikitsa interferometer, pali zofunikira zambiri pa malo ogwiritsira ntchito. Kugwedezeka kwa chilengedwe ndi kugwedezeka kwa ulusi wa kuwala kungakhudze zotsatira za mayeso.
