Ubwoko bwa moderi ya electro-optique isobanuwe muri make

Moderi ya electro-optique (EOM) igenzura imbaraga, icyiciro hamwe na polarisiyasi yumurambararo wa laser mugukoresha ibimenyetso bya elegitoroniki.
Moderi yoroshye ya electro-optique ni moderi ya moderi igizwe nagasanduku kamwe gusa ka Pockels, aho umurima wamashanyarazi (ushyirwa kuri kristu na electrode) uhindura gutinda kwicyiciro cya laser nyuma yo kwinjira muri kristu. Imiterere ya polarisiyasi yibyabaye mubisanzwe igomba kuba ihwanye nimwe mumashoka ya optique ya kristu kugirango imiterere ya polarisiyasi idahinduka.

Rimwe na rimwe birasabwa gusa icyiciro gito cyane (moderi cyangwa aperiodic). Kurugero, EOM isanzwe ikoreshwa mugucunga no gutuza resonant inshuro ya optique ya resonator. Modonulator ya resonance isanzwe ikoreshwa mugihe aho bisabwa guhinduka mugihe, kandi ubujyakuzimu bunini burashobora kuboneka hamwe na voltage yo gutwara gusa. Rimwe na rimwe, ubujyakuzimu ni bunini cyane, kandi sidelobe nyinshi (generator yumucyo, urumuri rwumucyo) ikorerwa murwego rwo hejuru.

Modulator
Ukurikije ubwoko nicyerekezo cya kristu idafite umurongo, kimwe nicyerekezo cyumuriro wamashanyarazi nyirizina, gutinda kwicyiciro nabyo bifitanye isano nicyerekezo cya polarisiyasi. Kubwibyo, agasanduku ka Pockels karashobora kubona amashanyarazi menshi agenzurwa nibyuma, kandi birashobora no gukoreshwa muguhindura leta. Kumucyo winjizamo urumuri rwinshi (mubisanzwe kuri Angle ya 45 ° uhereye kuri kristu ya kirisiti), polarisiyasi yibisohoka bisohoka mubisanzwe ni elliptike, aho kuzunguruka gusa na Angle uhereye kumucyo wambere utandukanijwe.

Amplitude modulator
Iyo uhujwe nibindi bintu bya optique, cyane hamwe na polarizeri, agasanduku ka Pockels karashobora gukoreshwa mubundi bwoko bwa modulation. Amplitude modulator mu gishushanyo cya 2 ikoresha agasanduku ka Pockels kugirango ihindure imiterere ya polarisiyasi, hanyuma ikoreshe polarizer kugirango ihindure ihinduka ryimiterere ya polarisiyasi ihinduka impinduka ya amplitude nimbaraga zumucyo woherejwe.
Bimwe mubisanzwe porogaramu ya moderi ya electro-optique irimo:
Guhindura imbaraga z'urumuri rwa laser, kurugero, kubicapiro rya laser, kwihuta kwamakuru yihuta, cyangwa itumanaho ryihuse;
Byakoreshejwe muburyo bwa laser frequency stabilisations, kurugero, ukoresheje uburyo bwa Pound-Drever-Hall;
Q ihinduranya muri lazeri ikomeye (aho EOM ikoreshwa mugufunga laser resonator mbere yimishwarara);
Uburyo bukora-gufunga (EOM modulation cavity gutakaza cyangwa icyiciro cyurugendo-rugendo, nibindi);
Guhindura pulses mubatoragura pulse, ibitekerezo byiza byongera ibitekerezo hamwe na lazeri.
