Kushandiswa kwetekinoroji yemodulator yemagetsi-optic
Modulator yeElectro-optic (Electro-optic modulator)Modulator yeEOM） chinhu chinodzora masaini chinoshandisa electro-optic effect kugadzirisa chiedza. Nheyo yaro yekushanda inowanzo wanikwa kuburikidza nePockels effect (Pockels effect, kureva Pockels effect), iyo inoshandisa mukana wekuti refractive index yezvinhu zvisiri zvemagetsi inoshanduka pasi pesimba remagetsi.
Chimiro chikuru che electro-optic modulator chinowanzo sanganisira kristaro (Pockels crystal) ine electro-optical effect, uye chinhu chinowanzo shandiswa i lithium niobate (LiNbO₃). Voltage inodiwa kuti pave nekuchinja kwechikamu inonzi Half-wave voltage. Kune makristaro ePockels, mazana kana kunyange zviuru zvevolts zvinowanzo dikanwa, saka kudiwa kwema amplifiers ane voltage yepamusoro. Dunhu remagetsi rakakodzera rinogona kuchinja voltage yakadaro mumasekonzi mashoma, zvichiita kuti EOM ishandiswe se switch yekukurumidza; Nekuda kwe capacitive yePockels crystals, madhiraivha aya anofanirwa kupa huwandu hwakawanda hwe current (kana paine fast switching kana modulation, capacitance inofanira kuderedzwa kuderedza kurasikirwa kwesimba). Mune zvimwe zviitiko, senge kana paine amplitude diki kana phase modulation chete, voltage diki chete ndiyo inodiwa kuti modulation ishande. Zvimwe zvinhu zvekristaro zvisiri zvemutsara zvinoshandiswa muma electro-optical modulators (Modulator yeEOM) zvinosanganisira potassium titanate (KTP), beta-barium borate (BBO, yakakodzera simba repakati nepakati uye/kana ma frequency ekuchinja akakwira), lithium tantalate (LiTaO3), uye ammonium phosphate (NH4H2PO4, ADP, ine hunhu hwakasiyana hwe electro-optical).
Electro-optic modulators (Magetsi emagetsi)Modulator yeEO） inoratidza kugona kwakakosha kwekushandisa muminda yakati wandei yetekinoroji yepamusoro:
1. Kutaurirana nefiber yemaziso: Muma network emazuva ano ekutaurirana, ma electro-optical modulators（Modulator yeEO） anoshandiswa kugadzirisa masaini ekuona, zvichiita kuti data rifambe zvakanaka uye rakavimbika munzvimbo refu. Nekudzora kwakarurama chikamu kana amplitude yechiedza, kutumira ruzivo nekukurumidza uye kwakakura kunogona kuitwa.
2. Kunyatsoongorora spectroscopy: Electro-optical modulator inogadzirisa chiedza chiri muspectrometer kuti ivandudze kurongeka kwekuyera. Nekukurumidza kugadzirisa frequency kana phase yechiratidzo cheoptical, kuongororwa nekuzivikanwa kwezvikamu zvakaoma zvemakemikari zvinogona kutsigirwa, uye kugadziriswa nekunzwa kwekuyera kwespectral kunogona kuvandudzwa.
3. Kugadziriswa kwedata remagetsi rinoita basa repamusoro: modulator yemagetsi-optical mu optical computing uye data processing system, kuburikidza nekuchinja kwezviratidzo zvemagetsi panguva chaiyo kuti zvivandudze kukurumidza kwedata uye kuchinjika. Nekupindura nekukurumidza kweEOM, kugadzirisa nekutumirwa kwedata remagetsi rinoita nekukurumidza uye kunonoka kwakaderera kunogona kuitika.
4. Tekinoroji yeLaser: Electro-optic modulator inogona kudzora phase uye amplitude yelaser beam, ichipa rutsigiro rwemifananidzo chaiyo, kugadzirwa nelaser nezvimwe zvinoshandiswa. Nekugadzirisa nemazvo maparameter elaser beam, kugadzirwa nelaser yemhando yepamusoro kunogona kuwanikwa.
