Ikoreshwa ry'ikoranabuhanga rya modulator ya electro-optique

Ikoreshwa ry'ikoranabuhanga ryamodulator y'amashanyarazi n'amatara

Modulator ya Electro-optic（Modulator ya EOM） ni ikintu cyo kugenzura ibimenyetso gikoresha ingaruka za electro-optic kugira ngo gihindure urumuri. Ihame ryacyo ry’imikorere muri rusange rigerwaho binyuze mu ngaruka za Pockels (ingaruka za Pockels, ni ukuvuga ingaruka za Pockels), zifashisha ikintu cy’uko imiterere y’ibikoresho bidafite umurongo ugororotse ihinduka bitewe n’imikorere y’amashanyarazi.

Imiterere y'ibanze ya modulator ya electro-optic ubusanzwe iba irimo kristu (Pockels crystal) ifite ingaruka za electro-optical, kandi ibikoresho bisanzwe ni lithium niobate (LiNbO₃). Voltage ikenewe kugira ngo habeho impinduka mu cyiciro yitwa voltage ya Half-wave. Kuri kristu za Pockels, volts amagana cyangwa ibihumbi ni byo bikunze gukenerwa, bityo hakaba hakenewe amplifiers zifite voltage nyinshi. Urugendo rwa elegitoroniki rukwiye rushobora guhindura voltage nyinshi mu masegonda make, bigatuma EOM ikoreshwa nk'ingufu zihuse; Bitewe n'ubushobozi bwa kristu za Pockels, izi mashini zigomba gutanga ingufu nyinshi (mu gihe cyo guhindura cyangwa guhinduranya byihuse, ubushobozi bugomba kugabanuka kugira ngo bigabanye igihombo cy'ingufu). Mu bindi bihe, nko mu gihe hakenewe amplitude nto cyangwa modulation y'igice, hakenewe voltage nto gusa kugira ngo hahindurwe. Ibindi bikoresho bya kristu bitari umurongo ugororotse bikoreshwa muri modulator za electro-optical (Modulator ya EOM) harimo potasiyumu titanate (KTP), beta-barium borate (BBO, ikwiriye ingufu zisanzwe cyangwa frequencies nyinshi zo guhinduranya), lithiyumu tantalate (LiTaO3), na ammonium phosphate (NH4H2PO4, ADP, ifite imiterere yihariye ya electro-optical).

Modulator za Electro-optic（Umuhuzabikorwa wa EO) zigaragaza ubushobozi bw'ingenzi mu gukoresha ibikoresho mu nzego zitandukanye z'ikoranabuhanga rigezweho:

1. Itumanaho rya fibre optique: Mu miyoboro ya none y'itumanaho, modulator z'amashanyarazi n'amataraUmuhuzabikorwa wa EO） bikoreshwa mu guhindura ibimenyetso by'urumuri, bigamije kohereza amakuru neza kandi yizewe mu ntera ndende. Mu kugenzura neza urwego cyangwa uburebure bw'urumuri, kohereza amakuru mu buryo bwihuse kandi bunini bishobora kugerwaho.

2. Uburyo bwo gupima neza: Uburyo bwo gupima neza bukoresha electro-optical modulator kugira ngo buhindure urumuri muri spectrometer kugira ngo burusheho kunoza uburyo bwo gupima. Mu guhindura vuba inshuro cyangwa icyiciro cy'ikimenyetso cy'urumuri, isesengura n'imenyekana ry'ibice by'ibinyabutabire bigoye bishobora gushyigikirwa, kandi ubushobozi bwo gupima neza no gusobanukirwa neza ibintu bishobora kunozwa.

3. Gutunganya amakuru y’urumuri mu buryo bwo hejuru: modulator y’amashanyarazi muri sisitemu yo gutunganya amakuru n’iy’ikoranabuhanga, binyuze mu guhindura ibimenyetso by’urumuri mu buryo bwihuse kugira ngo hongerwe umuvuduko wo gutunganya amakuru no koroshya imikorere. Hamwe n’uburyo bwo gusubiza bwihuse bwa EOM, gutunganya no kohereza amakuru y’urumuri mu buryo bwihuse kandi budatinze bishobora gukorwa.

4. Ikoranabuhanga rya Laser: Modulator ya electro-optic ishobora kugenzura urwego n'uburebure bw'umurabyo wa laser, igatanga ubufasha mu gufata amashusho neza, gutunganya laser n'izindi porogaramu. Mu guhindura neza ibipimo by'umurabyo wa laser, gutunganya laser nziza cyane bishobora kugerwaho.
