Nghọta zuru oke nke ndị modul eletrọ-optic
Igwe ihe eji electro optic modulator (EOM) bụ ihe ntụgharị eletrọnịkị nke na-eji akara eletrọnịkị chịkwaa akara ngosi anya, nke a na-ejikarị na usoro ngbanwe akara ngosi n'ọhịa teknụzụ nkwukọrịta.
Ihe na-esonụ bụ mmeghe zuru ezu maka modulator electro-optic:
1. The isi ụkpụrụ nkeelectrooptic modulatordabere na mmetụta electro-optic, ya bụ, ntugharị refractive nke ụfọdụ ihe ga-agbanwe n'okpuru ọrụ nke ọkụ eletrik etinyere. Ka ebili mmiri ọkụ na-agafe na kristal ndị a, njirimara mgbasa na-agbanwe na mpaghara eletrik. N'iji ụkpụrụ a, usoro, njupụta ma ọ bụ polarization steeti nkengwa anyaenwere ike ịchịkwa mgbaàmà site n'ịgbanwe mpaghara eletrik etinyere.
2. Ọdịdị na mejupụtara Electro-optical modulators bụ n'ozuzu mejupụtara nke anya ụzọ, amplifiers, nzacha na photoelectric converters. Na mgbakwunye, ọ na-agụnye ihe ndị bụ isi dị ka ndị ọkwọ ụgbọ ala dị elu, eriri anya na kristal piezoelectric. Nhazi nke modulator electro-optic nwere ike ịdịgasị iche dabere na ọnọdụ mgbanwe ya na ngwa chọrọ, mana na-agụnye akụkụ abụọ: modul inverter electro-optic na photoelectric modulation modul.
3. Modulation mode Electro-optic modulator nwere isi modulation ụdịdị abụọ:usoro modulationna mgbanwe mgbanwe ike. Mgbanwe usoro: Usoro nke ebu na-agbanwe ka mgbama a gbanwere agbanwe. Na Pockels electro-optic modulator, ọkụ na-ebu-ugboro na-agafe na kristal piezoelectric, na mgbe a na-etinye voltaji a gbanwere, a na-emepụta ọkụ eletrik na kristal piezoelectric, na-eme ka ntụgharị ntụgharị ya gbanwee, si otú ahụ gbanwee oge nke ìhè. .Mgbanwe ike: Ike (ọkụ ọkụ) nke onye na-ebu ngwa anya na-agbanwe ka mgbama a gbanwere agbanwe. A na-enwetakarị mgbanwe ike ike site na iji modulator ike nke Mach-Zehnder, nke dabara na ụkpụrụ na interferometer Mach-Zehnder. Mgbe ejiri ogwe aka na-agbanwe akụkụ nke nwere ike dị iche iche gbanwee ogwe abụọ ahụ, a na-etinye ha n'ikpeazụ ka ha wee nweta mgbama ngwa anya gbanwere ike.
4. Mpaghara ngwa eletrọnịkị modulators nwere ọtụtụ ngwa n'ọtụtụ mpaghara, gụnyere ma ọnweghị oke na: nkwurịta okwu anya: N'ime usoro nkwurịta okwu ngwa anya dị elu, a na-eji ndị na-eme mgbanwe elektrọnik iji gbanwee akara elektrọn ka ọ bụrụ akara ngosi anya. iji nweta ngbanwe data na nnyefe. Site n'ịgbanwe ike ma ọ bụ akụkụ nke mgbama ngwa anya, ọrụ nke ngbanwe ọkụ, njikwa ọnụego mgbanwe na mgbanwe mgbama nwere ike mezuo. Spectroscopy: Enwere ike iji modulators electro-optical dị ka akụkụ nke nyocha ihe nlere anya maka nyocha na nha anya. Ntụ aka nka: ndị na-ahụ maka elektrọn-optical modulators na-arụkwa ọrụ dị mkpa na sistemụ radar, nyocha ahụike na mpaghara ndị ọzọ. Dịka ọmụmaatụ, na usoro radar, enwere ike iji ya mee ihe maka mgbama mgbaama na demodulation; Na nyocha ahụike, enwere ike iji ya maka onyonyo anya na ọgwụgwọ. Ngwa ọhụrụ fotoelectric: eletrọnịkị modulators nwekwara ike iji rụpụta ngwaọrụ fotoelectric ọhụrụ, dị ka igwe ọkụ eletrọnịkị, ihe ndị na-ahụ anya, wdg.
5. Uru na ọghọm dị na modulator Electro-optic nwere ọtụtụ uru, dị ka ntụkwasị obi dị elu, obere ike oriri, ntinye dị mfe, obere nha na ihe ndị ọzọ. N'otu oge ahụ, ọ nwekwara ezigbo àgwà eletriki na ikike mgbochi nnyonye anya, nke a pụrụ iji mee ihe maka mgbasa ozi brọdband na ọtụtụ mkpa nhazi mgbaàmà. Agbanyeghị, modulator electrooptic nwekwara ụfọdụ adịghị ike, dị ka igbu oge mbufe mgbaàmà, ọ dị mfe ebili mmiri elektrọnịkị mpụga na-egbochi ya. Ya mere, mgbe ị na-eji modulator electro-optic, ọ dị mkpa ịhọrọ ngwaahịa ziri ezi dịka ngwa ngwa dị mkpa iji nweta ezigbo mmetụta na arụmọrụ. Na nchịkọta, modulator electro-optic bụ ihe ntụgharị electro-optic dị mkpa, nke nwere atụmanya ngwa dị ukwuu n'ọtụtụ mpaghara dị ka nkwurịta okwu anya, spectroscopy na nhazi teknụzụ.
Site na ọganihu sayensị na teknụzụ na-aga n'ihu na mmụba na-achọ ngwa ngwa ngwa anya dị elu, electro-optical modulators ga-emepewanye ma tinye ya n'ọrụ.
