Gusobanukirwa neza modulators za electro-optic
Modulator ya Electro-optic (EOM) ni igikoresho gihindura amashanyarazi gikoresha ibimenyetso by'amashanyarazi mu kugenzura ibimenyetso by'urumuri, gikoreshwa cyane cyane mu guhindura ibimenyetso by'urumuri mu rwego rw'ikoranabuhanga mu itumanaho.
Ibi bikurikira ni intangiriro irambuye kuri modulator ya electro-optic:
1. Ihame ry'ibanze ryamodulator y'amashanyarazi n'amataraishingiye ku ngaruka za electro-optic, ni ukuvuga ko igipimo cyo kurekura cy'ibikoresho bimwe na bimwe kizahinduka bitewe n'imikorere y'umurima w'amashanyarazi ukoreshejwe. Uko imiraba y'urumuri inyura muri izi kristu, imiterere y'ikwirakwira ry'umurima w'amashanyarazi irahinduka. Dukoresheje iri hame, imiterere y'urwego, amplitude cyangwa polarisation yaitara ry'amasoikimenyetso gishobora kugenzurwa hakoreshejwe guhindura amashanyarazi akoreshwa.
2. Imiterere n'imiterere y'ibikoresho bya elegitoroniki muri rusange bigizwe n'inzira z'urumuri, amplifiers, filters na fotoelectric converters. Byongeye kandi, birimo ibice by'ingenzi nka drivers zihuta cyane, fibre optique na piezoelectric crystals. Imiterere ya electro-optics modulator ishobora gutandukana bitewe n'uburyo bwo guhindura imiterere n'ibisabwa mu ikoreshwa ryayo, ariko akenshi irimo ibice bibiri: electro-optique inverter module na photoelectric modulation module.
3. Uburyo bwo guhindura imiterere y'amajwi (Modulation mode) Electro-optic modulator ifite uburyo bubiri bw'ingenzi bwo guhindura imiterere y'amajwi:ihindagurika ry'ibyiciron'uburyo imbaraga zihinduka. Uburyo ingufu zihinduka: Uburyo ingufu zihinduka uko ikimenyetso cyahinduwe. Muri modulator ya Pockels electro-optic, urumuri rwa carrier-frequency runyura muri crystal ya piezoelectric, kandi iyo voltage yahinduwe, ingufu z'amashanyarazi zikorwa muri crystal ya piezoelectric, bigatuma refractive index yayo ihinduka, bityo bigatuma urwego rw'urumuri ruhinduka.Guhindura imbaraga: Ubukana (ubukana bw'urumuri) bw'icyuma gitwara urumuri burahinduka uko ikimenyetso cyahinduwe gihinduka. Ubusanzwe uburyo imbaraga zihinduka hakoreshejwe uburyo bwa Mach-Zehnder intensity modulator, bungana na interferometer ya Mach-Zehnder. Nyuma y'uko imirasire ibiri ihinduwe n'ukuboko guhindagurika kw'impinduka zitandukanye, amaherezo iravangwa kugira ngo ikimenyetso cy'urumuri gihindurwe impagarara.
4. Ahantu hakoreshwa Electro-optical modulators ifite uburyo bwinshi bwo gukoresha mu nzego zitandukanye, harimo ariko ntigahagarikire kuri: itumanaho ry’amajwi: Muri sisitemu y’itumanaho ryihuse cyane, electro-optical modulators zikoreshwa mu guhindura ibimenyetso by’ikoranabuhanga mo ibimenyetso by’amajwi kugira ngo hagerwe ku gusimbuza no kohereza amakuru. Mu guhindura ubukana cyangwa icyiciro cy’ibimenyetso by’amajwi, imirimo yo guhindura urumuri, kugenzura umuvuduko w’impinduka no guhindura ibimenyetso irashobora kugerwaho. Spectroscopy: Electro-optical modulators zishobora gukoreshwa nk'ibice bigize optical spectrum analyzers mu gusesengura no gupima spectral. Ibipimo bya tekiniki: Electro-optical modulators nazo zigira uruhare runini muri sisitemu za radar, gusuzuma indwara n'izindi nzego. Urugero, muri sisitemu za radar, ishobora gukoreshwa mu guhindura ibimenyetso no gukuramo ibimenyetso; Mu gusuzuma indwara, ishobora gukoreshwa mu gufata amashusho no kuvura. Ibikoresho bishya by’amashanyarazi: electro-optical modulators zishobora kandi gukoreshwa mu gukora ibikoresho bishya by’amashanyarazi, nka switches za electro-optical, optical isolators, nibindi.
5. Ibyiza n'ibibi Modulator ya Electro-optic ifite ibyiza byinshi, nko kwizera cyane, gukoresha ingufu nke, koroshya kuyishyiraho, ingano nto n'ibindi. Ariko kandi, ifite imiterere myiza y'amashanyarazi n'ubushobozi bwo kwirinda kubangamira, ishobora gukoreshwa mu kohereza umuyoboro wa interineti no mu buryo butandukanye bwo gutunganya ibimenyetso. Ariko, modulator ya electro-optic ifite kandi inenge zimwe na zimwe, nko gutinda kohereza ibimenyetso, koroshya kwivanga n'imiraba ya electromagnetic yo hanze. Kubwibyo, iyo ukoresha modulator ya electro-optic, ni ngombwa guhitamo ibicuruzwa bikwiye hakurikijwe ibyo ikoreshwa kugira ngo ugere ku ngaruka nziza zo guhindura no gukora neza. Muri make, modulator ya electro-optic ni igikoresho cy'ingenzi cyo guhindura electro-optic, gifite amahirwe menshi yo gukoresha mu nzego nyinshi nko mu itumanaho ry'amajwi, spectroscopy no gupima tekiniki.
Bitewe n’iterambere rikomeje mu bumenyi n’ikoranabuhanga hamwe n’ubwiyongere bw’ubukene bw’ibikoresho by’ikoranabuhanga bikora neza cyane, modulator z’amashanyarazi zizarushaho gutezwa imbere no gukoreshwa.
