Modulator y'amajwi ni iki?

Modulator y'urumuribikunze gukoreshwa mu guhindura imiterere y'imirasire y'urumuri, nk'imirasire ya laser. Igikoresho gishobora guhindura imiterere y'imirasire, nk'ingufu z'urumuri cyangwa phase. Modulator ikurikije imiterere y'imirasire yahinduwe yitwamodulator y'ubukana, modulator y'icyiciro, modulator ya polarization, modulator y'amajwi y'ahantu, n'ibindi. Ubwoko butandukanye bwa modulator bushobora gukoreshwa mu bikorwa bitandukanye, nko mu itumanaho rya fiber optic, ibikoresho byo kwerekana, lazeri za Q-switched cyangwa mode-locked, hamwe no gupima optical.

Ubwoko bwa modulator y'urumuri

Hari ubwoko butandukanye bwa modulator:

1. Acousto-optic modulator ni modulator ishingiye ku ngaruka za acousto-optic. Ikoreshwa mu guhindura cyangwa guhindura buri gihe uburebure bw'umurabyo wa laser, guhindura ingano y'urumuri, cyangwa guhindura icyerekezo cy'umwanya.

2. Itsindamodulator y'amashanyarazi n'amataraikoresha ingaruka za electro-optic mu gasanduku ka Kerrs k'umutuku. Zishobora guhindura imiterere ya polarization, phase, cyangwa imbaraga za beam, cyangwa zigakoreshwa mu gukuramo pulse nk'uko byavuzwe mu gice kivuga ku byuma bikurura pulse bigufi cyane.

3. Modulator y'amashanyarazi ni modulator y'ingufu ikoreshwa ku cyuma gitanga amakuru mu itumanaho rya fibre optique.

(4) Utwuma dukoresha uburyo bwo kubangamira amakuru, nka Mach-Zehnder modulators, dukoreshwa mu buryo bwa fotonike buhuriweho mu kohereza amakuru y’urumuri.

5. Udukoresho twa fibre optique dushobora gushingira ku mahame atandukanye. Dushobora kuba igikoresho nyacyo cya fibre optique, cyangwa se kikaba igice cy'umubiri kirimo imirizo ya fibre.

6. Modulator ya crystal y'amazi ikwiriye gukoreshwa ku bikoresho byo kwerekana urumuri cyangwa pulse shaper. Ishobora kandi gukoreshwa nk'ibikoresho byo kugenzura urumuri rw'ikirere, bivuze ko uburyo bwo kohereza butandukana bitewe n'umwanya, bushobora gukoreshwa mu bikoresho byo kwerekana urumuri.

7. Disiki ya modulation ishobora guhindura imbaraga z'umurabyo rimwe na rimwe, ikoreshwa mu bipimo bimwe na bimwe by'urumuri (nk'ikoreshwa rya amplifiers zo gufunga).

8. Utwuma duto tw’ubukanishi (utumashini duto tw’ubukanishi, MEMS) nka vali z’urumuri zishingiye kuri silikoni n’udupira tw’indorerwamo tw’ibice bibiri ni ingenzi cyane mu kwerekana imiterere y’urumuri.

9. Utwuma dukoresha ikoranabuhanga ry'amashanyarazi, nka electro-optical modulators, dushobora gukoresha ahantu hanini ho gushyira urumuri kandi dushobora no gukoreshwa mu bihe by'ingufu nyinshi. Utwuma dukoresha ikoranabuhanga ry'amashanyarazi, akenshi dukoresha ikoranabuhanga ry'amashanyarazi rifite imirizo y'ingurube, tworoshye gushyira muri sisitemu ya ikoranabuhanga ry'amashanyarazi.

Gukoresha modulator y'amajwi

Modulators z'amajwi zifite uburyo bwinshi bwo gukoresha mu nzego nyinshi. Ibi bikurikira ni ibice by'ingenzi by'ikoreshwa rya modulators z'amajwi n'uburyo zikoreshwa byihariye:

1. Itumanaho ry'amajwi: Muri sisitemu y'itumanaho ry'amajwi, modulators z'amajwi zikoreshwa mu guhindura ubwinshi, ingano n'icyiciro cy'ibimenyetso by'amajwi kugira ngo byohereze amakuru. Bikunze gukoreshwa mu ntambwe z'ingenzi nko guhindura amashanyarazi, guhindura ibimenyetso by'amajwi no gukuraho ‌. Modulators z'amajwi ni ingenzi cyane muri sisitemu y'itumanaho ryihuse, zikoreshwa mu guhindura ibimenyetso by'ikoranabuhanga mo ibimenyetso by'amajwi no gutuma amakuru ashyirwa mu bikorwa. Mu guhindura ubukana cyangwa icyiciro cy'ibimenyetso by'amajwi, imirimo yo guhindura urumuri, kugenzura umuvuduko w'amajwi no guhindura ibimenyetso ishobora kugerwaho ‌

2. Gupima urumuri: Modulator y'urumuri ishobora kumenya gupima no gukurikirana ibidukikije ikoresheje guhindura imiterere y'ikimenyetso cy'urumuri. Urugero, binyuze mu guhindura imiterere y'urumuri cyangwa uburebure bwarwo, fibre optique gyroscopes, fibre optique pressure sensors, nibindi bishobora gukorwa.

3. Ububiko n'uburyo bwo gutunganya urumuri: Utwuma dukoresha urumuri dukoreshwa mu kubika urumuri no gutunganya urumuri. Mu bubiko bw'urumuri, utwuma dukoresha urumuri dushobora gukoreshwa mu kwandika no gusoma amakuru mu buryo bw'ikoranabuhanga. Mu gutunganya urumuri, utwuma dukoresha urumuri dushobora gukoreshwa mu gukora, kuyungurura, guhindura no gukuraho ibimenyetso by'urumuri

4. Ishusho y'urumuri: modulators z'urumuri zishobora gukoreshwa mu guhindura imiterere y'urumuri n'ubugari bw'urumuri, bityo bigahindura imiterere y'ishusho mu ifoto y'urumuri. Urugero, modulators z'urumuri zishobora gushyira mu bikorwa modulation y'ibice bibiri kugira ngo zihindure uburebure bw'umuraba n'ubujyakuzimu bw'umuraba.

5. Kugenzura urusaku rw'urumuri: Imashini ikoresha urumuri ishobora kugenzura ubukana n'inshuro z'urumuri, bityo ikagabanya cyangwa igahagarika urusaku rw'urumuri muri sisitemu y'urumuri. Ishobora gukoreshwa muri amplifiers z'urumuri, lasers na sisitemu yo kohereza fibre optique kugira ngo inoze ikigereranyo cy'urusaku hagati y'ibimenyetso n'imikorere ya sisitemu ‌

6. Izindi porogaramu: modulators za electro-optical nazo zikoreshwa mu gusesengura spectral, sisitemu za radar, gusuzuma indwara n'izindi nzego. Muri spectroscopy, modulators za electro-optical zishobora gukoreshwa nk'igice cya optical spectrum analyzer mu gusesengura no gupima spectral. Muri radar system, electro-optic modulator ikoreshwa mu guhindura ibimenyetso no gukuramo ibimenyetso. Mu gusuzuma indwara, modulators za electro-optic zikoreshwa mu gupima no kuvura ‌.
