Ụkpụrụ ọrụ nke nkịtịihe na-eme ka ike dịkwuo mma

Ụkpụrụ nke ihe na-eme ka ike dịkwuo elu dị iche iche dabere na ụdị ya. Ihe ndị a bụ ụkpụrụ ọrụ nke ihe na-eme ka ike dịkwuo elu:

1. Mach Zehnder Intensity Modulator (MZM Modulator)
Isi ụkpụrụ: Dabere na mmetụta nnyonye anya nke ìhè.Mgbanwe ike electro-opticbụ iji mmetụta electro-optic nke kristal wee nweta mgbanwe ike dabere na ụkpụrụ nnyonye anya nke ìhè polarized. Mmetụta electro-optic nke kristal na-ezo aka na ihe na-eme ka index refractive nke kristal gbanwee n'okpuru ọrụ nke ubi eletrik mpụga, na-akpata ọdịiche nke usoro n'etiti ìhè na-agafe na kristal na ntụziaka polarization dị iche iche, si otú a na-agbanwe ọnọdụ polarization nke ìhè.
Usoro ọrụ:
A na-ekewa ọkụ ntinye ahụ ụzọ abụọ site na ihe na-ekewa ìhè ma na-agafe ogwe aka abụọ nke nduzi ebili mmiri n'otu n'otu.
Itinye voltaji mpụga n'otu aka ma ọ bụ abụọ ahụ ma jiri mmetụta electro-optic (dịka mmetụta electro-optic linear nke kristal lithium niobate) gbanwee ntụaka refractive nke ntuziaka waveguide, si otú a gbanwee usoro nke ebili mmiri ọkụ dị na ogwe aka.
A na-ejikọta ọkụ abụọ ọzọ na njedebe mmepụta, n'ihi ọdịiche dị iche iche nke usoro, nnyonye anya nwere ike ime ihe ndị na-ewuli elu ma ọ bụ na-ebibi ihe, na-ebute mgbanwe na ike ọkụ mmepụta site na voltaji.
Mgbe ọdịiche nke usoro dị n'etiti ogwe aka abụọ ahụ bụ 0, ike nke ìhè mmepụta ga-adị oke elu (n'ọnọdụ "on"); Mgbe ọdịiche nke usoro bụ π, a na-ebelata ike nke ìhè mmepụta (n'ọnọdụ "gbanyụọ"), na-enweta mgbanwe ike.

2. Igwe Mgbakwunye Ike Elektrọnik (EAM)
Isi ụkpụrụ: Iji mmetụta electroabsorption nke ihe ndị dị na olulu mmiri kwantum mee ihe.
Usoro ọrụ:
Itinye oghere eletrik mpụga na ihe ndị na-emepụta ihe na-agbanwe ọnụọgụ nnabata nke ihe ahụ.
Mgbe ìhè gafere ihe, ike ya na-agbanwe n'ihi mgbanwe na njikọ nnabata, si otú a na-enweta mgbanwe ike ọkụ.
Ọ na-achọkarị mgbanwe echiche, ihe mgbaàmà eletriki ntinye nwere mmekọrịta dị elu na ike ọkụ mmepụta, na-eme ka ọ dabara adaba maka nkwukọrịta anya dị elu.

3.ihe na-eme ka ike acousto-optic dịkwuo mma
Isi ụkpụrụ: Dabere na mmetụta acousto-optic.
Usoro ọrụ:
Mepụta ebili mmiri ultrasonic na kristal iji mepụta grating na mgbanwe mgbanwe oge.
Mgbe ìhè gafere n'ime grating, diffraction na-eme, ike nke ìhè diffract na-ejikọtakwa ike nke ebili mmiri ultrasonic. Site n'ịchịkwa ike ma ọ bụ ugboro ole ebili mmiri ultrasonic na-eme, enwere ike ịgbanwe ike ọkụ mmepụta.

4. Ihe na-eme ka kristal dị ike nke mmiri mmiri
Isi ụkpụrụ: Iji njirimara nke kristal mmiri mmiri na-agbanwe nnyefe ya n'okpuru ọkụ eletrik.
Usoro ọrụ:
Nduzi nhazi nke molekul kristal mmiri mmiri na-agbanwe n'okpuru ọrụ nke ubi eletrik, na-emetụta nnyefe nke ìhè.
Site n'itinye voltaji dị iche iche iji chịkwaa nnyefe nke kristal mmiri mmiri, a na-agbanwe ike ọkụ mmepụta, nke a na-ejikarị eme ihe n'ọhịa ngosipụta na onyonyo.
Ụdị modulators dị iche iche nwere njirimara nke ha n'ihe gbasara ụkpụrụ, arụmọrụ, na ọnọdụ ngwa, a ga-ahọrọkwa ụdị kwesịrị ekwesị dịka mkpa ụfọdụ si dị.
