Yuav siv li casEO modulator
Tom qab tau txais EO modulator thiab qhib lub pob khoom, thov hnav cov hnab looj tes electrostatic / wristbands thaum kov lub plhaub hlau ntawm lub cuab yeej. Siv tweezers kom tshem tawm cov qhov nkag / qhov tso zis optical ntawm lub cuab yeej los ntawm cov grooves ntawm lub thawv, thiab tom qab ntawd tshem tawm lub cev tseem ceeb ntawm modulator los ntawm cov grooves daim txhuam cev. Tom qab ntawd tuav lub cev tseem ceeb ntawm EO modulator hauv ib txhais tes thiab rub lub qhov nkag / qhov tso zis optical ntawm modulator nrog lwm tus.
Kev npaj thiab kev tshuaj xyuas ua ntej siv
a. Saib xyuas kom tsis muaj kev puas tsuaj rau qhov chaw ntawm cov khoom, qhov chaw ntawm lub module thiab lub tes tsho fiber optical.
b. Xyuas kom daim ntawv lo tsis muaj av thiab cov cim luam ntawv silk-screen pom tseeb.
c. Lub flange hluav taws xob tsis puas tsuaj thiab txhua lub electrode pins tseem zoo.
d. Siv lub tshuab ntsuas qhov kawg ntawm cov fiber ntau los xyuas seb cov fiber ntau ntawm ob qho kawg puas huv.
1. Cov kauj ruam rau kev sivlub zog modulator
a. Xyuas seb qhov kawg ntawm cov fibers input/output optical ntawm lub intensity modulator puas huv. Yog tias muaj cov xim av, thov so lawv kom huv nrog cawv.
b. Lub intensity modulator yog ib qho input uas tswj tau polarization. Nws raug pom zoo kom siv lub teeb ci uas tswj tau polarization thaum siv (qhov wavelength ntawm lub teeb ci nyob ntawm qhov wavelength ntawm lub modulator), thiab lub zog teeb ntawm lub teeb ci zoo dua yog 10dBm.
Thaum siv lub zog modulator, txuas lub hwj chim GND rau tus pin 1 ntawm lub modulator, thiab lub davhlau ya nyob twg zoo ntawm lub hwj chim rau tus pin 2. Tus pin 3/4 yog cathode thiab anode ntawm PD sab hauv lub modulator. Yog tias koj xav tau siv nws, thov siv PD no nrog lub voj voog txais khoom ntawm qhov kawg tom qab, thiab PD no tuaj yeem siv yam tsis tas siv hluav taws xob (yog tias lub modulator tsis muaj PD sab hauv, tus pin 3/4 yog NC, tus pin ncua).
d. Cov khoom siv ntawm lub modulator zog yog lithium niobate. Thaum siv lub teb hluav taws xob, qhov ntsuas refractive ntawm lub siv lead ua yuav hloov pauv. Yog li ntawd, thaum muaj hluav taws xob siv rau lub modulator, qhov poob ntawm lub modulator yuav txawv nrog rau qhov hluav taws xob siv. Cov neeg siv tuaj yeem tswj lub modulator ntawm qee qhov chaw ua haujlwm raws li lawv siv.
Cov kev ceev faj
a. Qhov nkag ntawm lub modulator yuav tsum tsis pub tshaj qhov ntsuas ntawm daim ntawv xeem; txwv tsis pub, lub modulator yuav puas tsuaj.
b. Lub RF input ntawm lub modulator yuav tsum tsis pub tshaj qhov calibrated value ntawm daim ntawv xeem; txwv tsis pub, lub modulator yuav puas tsuaj.
c. Qhov voltage ntxiv ntawm lub modulator bias voltage pin yog ≤ ± 15V
2. Cov kauj ruam rau kev sivtheem modulator
a. Xyuas seb qhov kawg ntawm cov fibers input/output optical ntawm lub intensity modulator puas huv. Yog tias muaj cov xim av, thov so lawv kom huv nrog cawv.
b. Lub modulator theem yog ib qho input uas tswj tau polarization. Nws raug pom zoo kom siv lub teeb ci uas tswj tau polarization thaum siv (qhov wavelength ntawm lub teeb ci nyob ntawm qhov wavelength ntawm lub modulator), thiab lub zog teeb ntawm lub teeb ci zoo dua yog 10dBm.
c. Thaum siv lub modulator theem, txuas lub teeb liab RF rau qhov chaw nres nkoj RF ntawm lub modulator.
d. Tus modulator theem tuaj yeem ua haujlwm tom qab ntxiv lub teeb liab zaus xov tooj cua, ua kom tiav theemelectro-optic modulatorLub teeb modulated tsis tuaj yeem ntes tau ncaj qha los ntawm lub photodetector ua lub teeb liab zaus modulated. Feem ntau, yuav tsum teeb tsa interferometer, thiab lub teeb liab zaus xov tooj cua tsuas yog tuaj yeem ntes tau los ntawm lub photodetector tom qab cuam tshuam.
Cov kev ceev faj
a. Qhov nkag optical ntawm EO modulator yuav tsum tsis pub tshaj qhov calibration value ntawm daim ntawv xeem; txwv tsis pub, lub modulator yuav puas tsuaj.
b. Lub RF input ntawm EO modulator yuav tsum tsis pub tshaj qhov calibrated value ntawm daim ntawv xeem; txwv tsis pub, lub modulator yuav puas tsuaj.
c. Thaum teeb tsa lub interferometer, muaj cov kev cai siab heev rau qhov chaw siv. Kev co ntawm ib puag ncig thiab kev co ntawm cov fiber ntau tuaj yeem cuam tshuam rau cov txiaj ntsig ntawm kev sim.
