A kọwara ụdị ndị na-eme ka electro-optic modulators dị mkpirikpi.

Ihe na-eme ka ihe na-arụ ọrụ elektrọ-optical (EOM) na-achịkwa ike, usoro na polarization nke ọkụ laser site na iji eletrọniki na-achịkwa mgbaàmà ahụ.
Nke kachasị mfeihe na-eme ka electro-optic modulator dịbụmodulator nke usoronke nwere naanị otu igbe Pockels, ebe ọkụ eletrik (nke elektrọd na-etinye na kristal ahụ) na-agbanwe oge nkwụsị nke ogwe laser mgbe ọ banyere na kristal ahụ. Ọnọdụ polarisation nke ogwe ihe merenụ na-abụkarị ihe yiri otu n'ime axes anya nke kristal ahụ ka ọnọdụ polarisation nke ogwe ahụ ghara ịgbanwe.

N'ọnọdụ ụfọdụ, naanị obere usoro nhazi (oge maọbụ oge) ka achọrọ. Dịka ọmụmaatụ, a na-ejikarị EOM achịkwa ma mee ka ugboro resonant nke resonators optical sie ike. A na-ejikarị resonance modulators eme ihe n'ọnọdụ ebe achọrọ mgbanwe oge, enwere ike nweta nnukwu omimi modulation naanị site na voltaji draịva dị ala. Mgbe ụfọdụ, omimi modulation na-ebu ibu nke ukwuu, a na-emepụtakwa ọtụtụ akụkụ akụkụ (ihe na-emepụta comb ọkụ, comb ọkụ) na spectrum.

Ihe nhazi Polarization
Dabere n'ụdị na ntụziaka nke kristal na-abụghị ahịrị, yana ntụziaka nke ubi eletriki n'ezie, nkwụsịtụ nke usoro ahụ na-ejikọkwa na ntụziaka polarization. Ya mere, igbe Pockels nwere ike ịhụ efere ebili mmiri nwere ọtụtụ voltaji, enwere ike iji ya gbanwee ọnọdụ polarization. Maka ìhè ntinye nke nwere polarization (na-abụkarị n'akụkụ nke 45° site na axis kristal), polarization nke ìhè mmepụta na-abụkarị elliptic, kama ịtụgharị ya naanị site na Angle site na ìhè mbụ nwere polarized.

Ihe nhazi mmụba
Mgbe ejikọtara ya na ihe ndị ọzọ na-ahụ anya, ọkachasị na polarizers, enwere ike iji igbe Pockels mee ụdị modulation ndị ọzọ. Ihe modulator amplitude dị na Foto nke 2 na-eji igbe Pockels agbanwe ọnọdụ polarization, wee jiri polarizer gbanwee mgbanwe na ọnọdụ polarization ka ọ bụrụ mgbanwe na oke na ike nke ìhè ebufere.
Ụfọdụ ngwa ndị a na-ejikarị eme ihe maka modulators electro-optic gụnyere:
Ịgbanwe ike nke ọkụ laser, dịka ọmụmaatụ, maka ibipụta laser, ndekọ data dijitalụ dị elu, ma ọ bụ nkwukọrịta anya dị elu;
A na-eji usoro nhazi ugboro ole laser eme ihe, dịka ọmụmaatụ, site na iji usoro Pound-Drever-Hall;
