Ngwa ọhụrụ makaElektrọ-Optic modulator nke usoro
Ihe nhazi LiNbO3Ihe nhazi usoro bụ isi ihe nwere ike ijikwa mgbanwe usoro nke ebili mmiri ọkụ, ọ na-arụkwa ọrụ dị mkpa na nkwukọrịta anya na mmetụta nke oge a. N'oge na-adịbeghị anya, ụdị ọhụrụ nkemodulator nke usoroadọtala uche nke ndị nchọpụta na ndị injinia, nke na-arụ ọrụ na ogologo ebili mmiri atọ nke 780nm, 850nm na 1064nm, yana bandwidth modulation nke ruru 300MHz, 10GHz, 20GHz na 40GHz.
Ihe kachasị mkpa nke modulator nke usoro a bụ oke bandwit modulation na obere mfu ntinye. Mfu ntinye na-ezo aka na mbelata ike ma ọ bụ ike nke akara anya mgbe ọ gafere modulator. Mfu ntinye nke modulator nke usoro a dị oke ala, nke na-eme ka ihe mgbaàmà ahụ guzosie ike, ka ihe mgbaàmà ahụ wee nwee ike ịnọgide na-enwe ike dị elu mgbe emechara mgbanwe.
Tinyere nke ahụ, modulator nke usoro ahụ nwere njirimara nke obere voltaji ọkara-wave. Voltaji ọkara-wave bụ voltaji nke a ga-etinye na modulator iji gbanwee usoro nke ìhè site na ogo 180. Voltaji ọkara-wave dị ala pụtara na naanị voltaji dị ala ka achọrọ iji nweta nnukwu mgbanwe na usoro anya, nke na-ebelata oke oriri ike nke ngwaọrụ ahụ.
Maka mpaghara ngwa, enwere ike iji modulator nke usoro ọhụrụ a mee ihe n'ọtụtụ ebe na sensọ eriri optical, nkwukọrịta eriri optical, igbu oge usoro (shifter), na nkwukọrịta quantum. Na mmetụta eriri optical, modulator nke usoro nwere ike ime ka mmetụta na mkpebi nke sensọ dịkwuo mma. Na nkwukọrịta eriri optical, ọ nwere ike ime ka ọsọ nkwukọrịta na arụmọrụ nnyefe data ka mma. Na igbu oge usoro (shifter), ọ nwere ike ijikwa ntụziaka nke mgbasa ọkụ kpọmkwem; Na nkwukọrịta quantum, enwere ike iji ya chịkwaa ma jikwaa ọnọdụ quantum.
N'ozuzu, modulator nke usoro ọhụrụ a na-enye anyị ụzọ njikwa anya dị irè ma zie ezi karị, nke ga-eweta mgbanwe mgbanwe n'ọtụtụ ngalaba. Anyị na-atụ anya na teknụzụ a ga-emepe ma zuo oke n'ọdịnihu, na-ekpughe ihe omimi anya ndị ọzọ maka anyị.
