Uburyo bwo gukoreshaUmuhuzabikorwa wa EO
Nyuma yo kwakira modulator ya EO no gufungura ipaki, nyamuneka wambare uturindantoki/imikandara yo ku kuboko ya elegitoroniki mugihe ukora ku gice cy'icyuma cy'icyuma cy'igikoresho. Koresha utubuto kugira ngo ukureho imiyoboro y'icyuma/isohoka ry'igikoresho mu miyoboro y'agasanduku, hanyuma ukureho igice cy'ingenzi cya modulator mu miyoboro y'iponji. Hanyuma fata igice cy'ingenzi cya modulator ya EO mu kuboko kumwe hanyuma ukuremo igice cy'isohoka ry'umuyoboro w'icyuma n'ikindi.
Gutegura no kugenzura mbere yo gukoresha
a. Menya neza ko nta cyangiritse ku buso bw'ibicuruzwa, ubuso bwa module n'agasanduku k'umuyoboro w'amashanyarazi.
b. Genzura ko icyapa nta mwanda kirimo kandi ko ibimenyetso byo gucapa bya silk-screen bigaragara neza.
c. Umugozi w'amashanyarazi ntugira icyo wangirika kandi imigozi yose ya electrode nta kibazo ifite.
d. Koresha icyuma gipima impera z'urumuri kugira ngo urebe niba insinga z'urumuri ku mpera zombi zisukuye.
1. Intambwe zo gukoreshamodulator y'ubukana
a. Reba niba impande z'insinga z'amashanyarazi zinjira/zisohoka muri modulator y'ingufu zisukuye. Niba hari ibizinga, nyamuneka ubihanagure ukoresheje alcool.
b. Modulator y'ingufu ni uburyo bwo kubungabunga polarisation. Ni byiza gukoresha isoko y'urumuri ibungabunga polarisation iyo ikoreshwa (uburebure bw'urumuri buterwa n'uburebure bw'urumuri bukoreshwa na modulator), kandi imbaraga z'urumuri rw'urumuri ni 10dBm.
Mu gihe ukoresha modulator y'imbaraga, huza GND y'amashanyarazi kuri pin ya 1 ya modulator, n'aho terminal y'amashanyarazi kuri pin ya 2. Pin 3/4 ni cathode na anode bya PD iri muri modulator. Niba ukeneye kuyikoresha, nyamuneka koresha iyi PD hamwe na circuit yo kubona ku mpera y'inyuma, kandi iyi PD ishobora gukoreshwa nta voltage ikoreshejwe (niba modulator idafite PD y'imbere, pin 3/4 ni NC, pin ihagaze).
d. Ibikoresho bya modulator y'ingufu ni lithium niobate. Iyo hakoreshejwe amashanyarazi, imiterere y'ikirahure cya kristu irahinduka. Kubwibyo, iyo voltage ishyizwe kuri modulator, igihombo cyo kwinjira kwa modulator kizatandukana bitewe na voltage ikoreshejwe. Abakoresha bashobora kugenzura modulator ahantu runaka hakoreshwa bitewe n'uko ikoreshwa.
Amabwiriza yo Kwirinda
a. Ibyuma bikoresha modulator ntibigomba kurenza agaciro ko gupima ku rupapuro rw'igerageza; bitabaye ibyo, modulator izangirika.
b. RF yinjiye muri modulator ntigomba kurenza agaciro kagenwe ku rupapuro rw'igerageza; bitabaye ibyo, modulator izangirika.
c. Voltage yongeweho ya pin ya modulator bias voltage ni ≤±15V
2. Intambwe zo gukoreshamodulator y'icyiciro
a. Reba niba impande z'insinga z'amashanyarazi zinjira/zisohoka muri modulator y'ingufu zisukuye. Niba hari ibizinga, nyamuneka ubihanagure ukoresheje alcool.
b. Modulator y'icyiciro ni uburyo bwo kubungabunga polarisation. Ni byiza gukoresha isoko y'urumuri ibungabunga polarisation iyo ikoreshwa (uburebure bw'urumuri buterwa n'uburebure bw'urumuri bukoreshwa na modulator), kandi imbaraga z'urumuri rw'urumuri ni 10dBm.
c. Mu gihe ukoresha modulator y'icyiciro, huza ikimenyetso cya RF n'aho modulator yinjiye.
d. Imashini ikoresha ikoranabuhanga ry'icyiciro ishobora gukora nyuma yo kongeramo ikimenyetso cya radiyo, ikarangiza icyo cyiciromodulator y'amashanyarazi n'amatara. Urumuri rwahinduwe ntirushobora kubonwa mu buryo butaziguye na fotodecteur nk'ikimenyetso cya radiyo cyahinduwe. Ubusanzwe, interferometer igomba gushyirwaho, kandi ikimenyetso cya radiyo gishobora kubonwa gusa na fotodecteur nyuma yo kubangamirana.
Amabwiriza yo Kwirinda
a. Ibyuma bikoresha ikoranabuhanga rya EO modulator ntibigomba kurenza agaciro k'isuzuma ku rupapuro rw'igerageza; bitabaye ibyo, modulator izangirika.
b. RF yinjiye muri modulator ya EO ntigomba kurenza agaciro kagenwe ku rupapuro rw'igerageza; bitabaye ibyo, modulator izangirika.
c. Mu gushyiraho interferometer, hari ibisabwa byinshi ku bidukikije. Gutigita kw'ibidukikije no kunyeganyega kw'imigozi y'urumuri bishobora kugira ingaruka ku bisubizo by'ibizamini.
