Technology kushandiswa kweelectro-optic modulator
Electro-optic modulator.EOM modulator） chinhu chinodzora chiratidzo chinoshandisa iyo electro-optic mhedzisiro kugadzirisa mwenje wemwenje. Nheyo yaro yekushanda inowanikwa kuburikidza nePockels effect (Pockels effect, iyo inonzi Pockels effect), iyo inotora mukana wechiitiko chokuti refractive index ye nonlinear optical materials inoshanduka pasi pechiito chemagetsi emagetsi.
Iyo yakakosha chimiro che electro-optic modulator inowanzo sanganisira crystal (Pockels crystal) ine electro-optical effect, uye yakajairika zvinhu lithium niobate (LiNbO₃). Mhepo inodiwa kuti iite shanduko inonzi Half-wave voltage. Kune maPockels makristasi, mazana kana kunyange zviuru zvevolts zvinowanzodiwa, nekudaro kudiwa kweakakwira-voltage amplifiers. Iyo yakakodzera yemagetsi yedunhu inogona kushandura yakakwira voltage mune mashoma nanoseconds, ichibvumira EOM kuti ishandiswe sekukurumidza optical switch; Nekuda kweiyo capacitive hunhu hwePockels crystals, vatyairi ava vanofanirwa kupa huwandu hwakati wandei hwezvino (munyaya yekukurumidza kushandura kana modulation, iyo capacitance inofanirwa kuderedzwa kuderedza kurasikirwa kwesimba). Mune zvimwe zviitiko, senge apo chete diki amplitude kana chikamu modulation inodiwa, chete diki voltage inodiwa pakugadzirisa. Zvimwe zvisiri zvekristaro zvinhu zvinoshandiswa mu electro-optical modulators (EOM modulator) inosanganisira potassium titanate (KTP), beta-barium borate (BBO, yakakodzera paavhareji simba uye/kana yakakwirira switching frequencies), lithium tantalate (LiTaO3), uye ammonium phosphate (NH4H2PO4, ADP, ine chaiwo electro-optical properties).
Electro-optic modulators.EO modulator） ratidza kukosha kwekushandisa mukana mune akati wandei epamusoro-tech minda:
1. Optical fiber kutaurirana: Mumazuva ano enharembozha network, electro-optical modulators.EO modulator） anoshandiswa kuenzanisa zvikwangwani zvemaziso, kuve nechokwadi chekufambisa uye chakavimbika data kutapurirana pamusoro pemadaro marefu. Nekunyatso kudzora chikamu kana amplitude yechiedza, kukurumidza-kumhanya uye hukuru-hukuru hwekufambisa ruzivo hunogona kuwanikwa.
2. Precision spectroscopy: Iyo electro-optical modulator inogadzirisa chiedza chechiedza mu spectrometer kuvandudza kuyerwa kwechiyero. Nekukurumidza kugadzirisa kuwanda kana chikamu chechiratidzo che optical, kuongororwa uye kuzivikanwa kwezvakaoma zvemakemikari zvikamu zvinogona kutsigirwa, uye kugadzirisa uye kunzwisiswa kwekuyera kuyerwa kunogona kuvandudzwa.
3. High-performance optical data processing: electro-optical modulator mu optical computing uye data processing system, kuburikidza ne-real-time modulation ye optical signals yekuvandudza data processing speed uye kushanduka. Nekukurumidza kupindura maitiro eEOM, yakakwirira-kumhanya uye yakaderera-latency optical data kugadzirisa uye kutapurirana kunogona kuitika.
4. Laser tekinoroji: Iyo electro-optic modulator inogona kudzora chikamu uye amplitude ye laser beam, ichipa rutsigiro rwekufungidzira kwakaringana, laser process uye mamwe maapplication. Nekunyatso gadzirisa iyo paramita ye laser beam, yakakwira mhando laser processing inogona kuwanikwa.
