Kumvetsetsa kwathunthu kwa ma modulators a electro-optic
Chowongolera cha Electro-optic (EOM) ndi chosinthira chamagetsi chomwe chimagwiritsa ntchito zizindikiro zamagetsi kuwongolera zizindikiro zowala, zomwe zimagwiritsidwa ntchito makamaka munjira yosinthira zizindikiro zowala m'munda waukadaulo wolumikizirana.
Chiyambi cha electro-optic modulator ndi ichi:
1. Mfundo yaikulu yamodulator yamagetsiimachokera ku mphamvu ya electro-optic, kutanthauza kuti, chizindikiro cha refractive cha zinthu zina chidzasintha pansi pa mphamvu ya mphamvu yamagetsi yomwe yagwiritsidwa ntchito. Pamene mafunde a kuwala akudutsa m'makristalo awa, makhalidwe a kufalikira amasintha ndi mphamvu yamagetsi. Pogwiritsa ntchito mfundo imeneyi, gawo, amplitude kapena polarization state yakuwalachizindikiro chingawongoleredwe posintha mphamvu yamagetsi yomwe yagwiritsidwa ntchito.
2. Kapangidwe ndi kapangidwe kake Ma modulators a electro-optical nthawi zambiri amakhala ndi njira zowunikira, ma amplifiers, zosefera ndi ma photoelectric converters. Kuphatikiza apo, imaphatikizapo zigawo zofunika monga ma drivers othamanga kwambiri, ulusi wa optical ndi ma piezoelectric crystals. Kapangidwe ka electro-optic modulator kamatha kusiyana malinga ndi momwe imasinthira komanso zofunikira pakugwiritsa ntchito, koma nthawi zambiri kumakhala ndi magawo awiri: electro-optic inverter module ndi photoelectric modulation module.
3. Modulation mode Electro-optic modulator ili ndi njira ziwiri zazikulu zosinthira:kusintha kwa gawondi kusintha kwa mphamvu. Kusintha kwa gawo: Gawo la chonyamulira limasintha pamene chizindikiro chosinthidwa chikusintha. Mu Pockels electro-optic modulator, kuwala kwa carrier-frequency kumadutsa mu kristalo ya piezoelectric, ndipo magetsi akagwiritsidwa ntchito, mphamvu yamagetsi imapangidwa mu kristalo ya piezoelectric, zomwe zimapangitsa kuti refractive index yake isinthe, motero kusintha gawo la kuwala.Kusintha kwa mphamvu: Mphamvu (mphamvu yowala) ya chonyamulira kuwala imasintha pamene chizindikiro chosinthidwa chikusintha. Kusinthasintha kwa mphamvu nthawi zambiri kumachitika pogwiritsa ntchito Mach-Zehnder intensity modulator, yomwe ndi yofanana ndi Mach-Zehnder interferometer. Pambuyo poti ma beam awiriwa asinthidwa ndi phase shifting arm yokhala ndi mphamvu zosiyanasiyana, pamapeto pake amasokonezedwa kuti apeze chizindikiro chosinthika cha mphamvu.
4. Madera Ogwiritsira Ntchito Ma modulators a electro-optical ali ndi ntchito zosiyanasiyana m'magawo angapo, kuphatikiza koma osati kokha: kulumikizana kwa kuwala: Mu machitidwe olumikizirana a kuwala othamanga kwambiri, ma modulators a electro-optical amagwiritsidwa ntchito kusintha ma signal amagetsi kukhala ma signal optical kuti akwaniritse kuyika ndi kutumiza deta. Mwa kusintha mphamvu kapena gawo la chizindikiro cha kuwala, ntchito za kusintha kwa kuwala, kuwongolera liwiro la modulation ndi kusintha kwa ma signal zitha kuchitika. Spectroscopy: Ma modulators a electro-optical angagwiritsidwe ntchito ngati zigawo za optical spectrum analyzers kuti ayesedwe ndi kuyeza ma spectral. Muyeso waukadaulo: ma modulators a electro-optical amakhalanso ndi gawo lofunikira mu radar systems, diagnostics azachipatala ndi madera ena. Mwachitsanzo, mu radar systems, ingagwiritsidwe ntchito posintha ma signal ndi demodulation; Pa matenda azachipatala, ingagwiritsidwe ntchito pojambula ndi kuchiza ma optical. Zipangizo zatsopano zamagetsi: ma modulators a electro-optical angagwiritsidwenso ntchito popanga zida zatsopano zamagetsi, monga ma switch a electro-optical, optical isolators, ndi zina zotero.
5. Ubwino ndi kuipa kwa Electro-optic modulator ili ndi zabwino zambiri, monga kudalirika kwambiri, kugwiritsa ntchito mphamvu zochepa, kusavuta kuyiyika, kukula kochepa ndi zina zotero. Nthawi yomweyo, ilinso ndi mawonekedwe abwino amagetsi komanso kuthekera koletsa kusokonezedwa, komwe kungagwiritsidwe ntchito potumiza ma broadband ndi zosowa zosiyanasiyana zogwiritsira ntchito ma signal. Komabe, electro-optic modulator ilinso ndi zofooka zina, monga kuchedwa kutumiza ma signal, kusokonezeka mosavuta ndi mafunde akunja a electromagnetic. Chifukwa chake, mukamagwiritsa ntchito electro-optic modulator, ndikofunikira kusankha chinthu choyenera malinga ndi zosowa zenizeni kuti mukwaniritse zotsatira zabwino zosinthira ndi magwiridwe antchito. Mwachidule, electro-optic modulator ndi chosinthira chofunikira cha electro-optic, chomwe chili ndi mwayi waukulu wogwiritsa ntchito m'magawo ambiri monga kulumikizana kwa maso, spectroscopy ndi muyeso waukadaulo.
Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo komanso kufunikira kwakukulu kwa zida zamagetsi zogwira ntchito bwino, ma modulators amagetsi ndi kuwala adzapangidwa kwambiri ndikugwiritsidwa ntchito.
