Iyini i-Optical modulator?
I-modulator yokukhanyazivame ukusetshenziselwa ukushintsha izakhiwo zemisebe yokukhanya, njengemisebe ye-laser. Idivayisi ingaguqula izakhiwo zemisebe, njengamandla okukhanya noma isigaba. I-Modulator ngokwesimo semisebe eguquliwe ibizwa ngokuthii-modulator yokuqina, i-modulator yesigaba, i-polarization modulator, i-spatial Optical modulator, njll. Izinhlobo ezahlukene zama-modulator zingasetshenziswa ezinhlelweni zokusebenza ezahlukene, njengokuxhumana kwe-fiber optic, amadivayisi okubonisa, ama-laser e-Q-switched noma i-mode-locked, kanye nokulinganisa kwe-optical.
Uhlobo lwe-modulator ye-optical
Kunezinhlobo eziningana ezahlukene zama-modulator:
1. I-Acousto-optic modulator iyi-modulator esekelwe kumphumela we-acousto-optic. Isetshenziselwa ukushintsha noma ukulungisa njalo ubukhulu bomsebe we-laser, ukushintsha imvamisa yokukhanya, noma ukushintsha isiqondiso sesikhala.
2. Ii-electro-optic modulatorisebenzisa umphumela we-electro-optic ebhokisini le-bubble Kerrs. Zingaguqula isimo se-polarization, isigaba, noma amandla e-beam, noma zisetshenziselwe ukukhipha i-pulse njengoba kushiwo esigabeni sama-amplifiers e-pulse amafushane kakhulu.
3. I-modulator yokumunca kagesi iyi-modulator yokuqina esetshenziswa kusithumeli sedatha ekuxhumaneni nge-optical fiber.
(4) Ama-modulators okuphazamisa, njenge-Mach-Zehnder modulators, avame ukusetshenziswa kumasekethe ahlanganisiwe e-photonic ukuze kudluliselwe idatha ye-optical.
5. Ama-modulators e-fibre optic angasekelwa ezimisweni ezahlukahlukene. Kungaba idivayisi yangempela ye-fiber optic, noma kungaba yingxenye yomzimba equkethe i-fiber pigtails.
6. I-modulator yekristalu yolwelo ifanele ukusetshenziswa emishinini yokubonisa i-optical noma i-pulse shaper. Ingasetshenziswa futhi njenge-modulators yokukhanya kwendawo, okusho ukuthi ukudluliselwa kuyahlukahluka ngesikhala, esingasetshenziswa kumadivayisi okubonisa.
7. Idiski yokushintsha ingashintsha amandla ogongolo ngezikhathi ezithile, olusetshenziswa kwezinye izilinganiso ezithile zokukhanya (njengokusebenzisa ama-amplifier okukhiya).
8. Ama-modulators e-Micromechanical (izinhlelo ze-micromechanical, i-MEMS) njenge-valve yokukhanya esekelwe ku-silicon kanye nama-mirror arrays amabili abaluleke kakhulu ekubonisweni kwe-projection.
9. Ama-modulators e-optical amakhulu, njenge-electro-optical modulators, angasebenzisa indawo enkulu ye-beam futhi angasetshenziswa nasezimweni zamandla aphezulu. Ama-modulators ahlanganiswe ne-fibre, ngokuvamile ama-modulators e-waveguide ane-fiber pigtails, kulula ukuwahlanganisa ezinhlelweni ze-fiber optic.
Ukusetshenziswa kwe-modulator ye-Optical
Ama-modulators e-Optical anezinhlelo zokusebenza eziningi emikhakheni eminingi. Lokhu okulandelayo yizindawo eziyinhloko zokusetshenziswa kwama-modulators e-Optical kanye nezinhlelo zawo ezithile:
1. Ukuxhumana Okubonakalayo: Ezinhlelweni zokuxhumana okubonakalayo, ama-modulators optical asetshenziswa ukuguqula ubukhulu, imvamisa kanye nesigaba sezimpawu zokukhanya ukuze kudluliselwe ulwazi. Ngokuvamile asetshenziswa ezinyathelweni ezibalulekile njengokuguqulwa kwe-photoelectric, ukuguqulwa kwesignali optical kanye nokususwa kwe-. Ama-modulators e-electro-optic abaluleke kakhulu ezinhlelweni zokuxhumana ezisheshayo, ezisetshenziselwa ukuguqula izimpawu ze-elekthronikhi zibe izimpawu zokukhanya futhi zenze ukufakwa kwekhodi kwedatha kanye nokudluliselwa kwayo. Ngokuguqula ubukhali noma isigaba sesignali optical, imisebenzi yokushintsha ukukhanya, ukulawula izinga lokuguquguquka kanye nokuguqulwa kwesignali ingafezeka
2. Ukuzwa kokukhanya: I-modulator yokukhanya ingabona ukulinganiswa nokuqapha indawo ngokushintsha izici zesignali yokukhanya. Isibonelo, ngokushintsha isigaba noma ubukhulu bokukhanya, ama-gyroscope e-fiber optic, izinzwa zokucindezela kwe-fiber optic, njll. kungabonakala
3. Isitoreji kanye nokucubungula kwe-Optical: Ama-modulators e-Optical asetshenziselwa isitoreji se-optical kanye nezinhlelo zokusebenza zokucubungula kwe-optical. Kumemori ye-optical, ama-modulators e-optical angasetshenziswa ukubhala nokufunda ulwazi ngaphakathi nangaphandle kwemidiya ye-optical. Ekucubungulweni kwe-optical, i-modulator ye-optical ingasetshenziswa ekwakheni, ekuhlungeni, ekuguquleni nasekuhlukaniseni izimpawu ze-optical
4. Ukuthwebula izithombe ngokubona: ama-modulators optical angasetshenziswa ukuguqula isigaba kanye nobukhulu bomsebe wokukhanya, ngaleyo ndlela ashintshe izici zesithombe ekuthwebula izithombe ngokubona. Isibonelo, i-modulator yensimu yokukhanya ingasebenzisa ukuguqulwa kwesigaba okunezinhlangothi ezimbili ukushintsha ubude bokugxila kanye nokujula kokugxila komsebe
5. Ukulawulwa komsindo obonakalayo: I-modulator yokukhanya ingalawula ubukhali kanye nemvamisa yokukhanya, ngaleyo ndlela inciphise noma icindezele umsindo obonakalayo ohlelweni lokukhanya. Ingasetshenziswa kuma-amplifier optical, ama-laser kanye nezinhlelo zokudlulisa i-fiber optic ukuthuthukisa isilinganiso sesiginali kuya komsindo kanye nokusebenza kohlelo
6. Ezinye izinhlelo zokusebenza: ama-modulators e-electro-optical asetshenziswa nasekuhlaziyweni kwe-spectral, izinhlelo ze-radar, ukuxilongwa kwezokwelapha kanye neminye imikhakha. Ku-spectroscopy, i-modulator ye-electro-optical ingasetshenziswa njengengxenye ye-optical spectrum analyzer yokuhlaziywa kwe-spectral kanye nokulinganiswa. Kuhlelo lwe-radar, i-electro-optic modulator isetshenziselwa ukuguqulwa kwesignali kanye nokususwa kwe-demodulation. Ekuxilongweni kwezokwelapha, ama-modulators e-electro-optic asetshenziswa ekuthathweni kwezithombe kanye nokwelashwa kwe-optical .
