3. I-modulator yokungenisa umbane yi-modulator yokuqina esetyenziswa kwi-data transmitter kunxibelelwano lwe-optical fiber.
(4) Iimodulators zokuphazamisa, ezifana neemodulators zeMach-Zehnder, zihlala zisetyenziswa kwiisekethe ezidityanisiweyo ze-photonic zokuhambisa idatha ye-optical.
5. Iimodulators ze-fiber optic zinokusekelwa kwimigaqo eyahlukeneyo. Isenokuba sisixhobo sokwenyani se-fiber optic, okanye ingaba yinxalenye yomzimba equlethe i-fiber pigtails.
6. I-modulator yekristale yolwelo ifanelekile ukusetyenziswa kwizixhobo zokubonisa ukukhanya okanye kwi-pulse shaper. Zingasetyenziswa njengee-modulators zokukhanya kwendawo, oko kuthetha ukuba uthumelo luyahluka ngokwendawo, olunokusetyenziswa kwizixhobo zokubonisa.
7. Idiski yokuguqula i-modulation inokutshintsha amandla e-beam ngamaxesha athile, asetyenziswa kwiimilinganiselo ezithile ze-optical (njengokusebenzisa ii-amplifiers zokutshixa).
8. Iimodulators zeMicromechanical (iinkqubo zeMicromechanical, iiMEMS) ezifana neevalvu zokukhanya ezisekwe kwisilicon kunye nee-mirror arrays ezinemilinganiselo emibini zibaluleke kakhulu kwizibonisi zeprojektha.
9. Iimodulators ze-optical ezinkulu, ezifana neemodulators ze-electro-optical, zinokusebenzisa indawo enkulu yemitha kwaye zingasetyenziswa nakwiimeko ezinamandla aphezulu. Iimodulators ezidityanisiweyo zefayibha, ezidla ngokuba ziimodulators ze-waveguide ezinee-fiber pigtails, kulula ukuzidibanisa kwiinkqubo ze-fiber optic.
Ukusetyenziswa kwe-Optical modulator
Ii-modulators ze-Optical zineendlela ezahlukeneyo zokusetyenziswa kwiindawo ezininzi. Ezi zilandelayo zezona ndawo ziphambili zokusetyenziswa kwee-Optical modulators kunye nezicelo zazo ezithile:
1. Unxibelelwano lwe-Optical: Kwiinkqubo zonxibelelwano lwe-optical, ii-optical modulators zisetyenziselwa ukuguqula ubukhulu, i-frequency kunye ne-phase ye-optical signals ukuze kudluliselwe ulwazi. Isetyenziswa rhoqo kumanyathelo aphambili afana nokuguqulwa kwe-photoelectric, i-optical signal modulation kunye ne-demodulation . Ii-electro-optic modulators zibaluleke kakhulu kwiinkqubo zonxibelelwano lwe-optical ezinesantya esiphezulu, ezisetyenziselwa ukuguqula i-electronic signals zibe yi-optical signals kunye nokuqonda i-data encoding kunye ne-transmission. Ngokuguqula amandla okanye i-phase ye-optical signal, imisebenzi yokutshintsha ukukhanya, ulawulo lwe-modulation rate kunye ne-signal modulation inokufezekiswa
2. Ukubona okubonakalayo: I-optical modulator inokuqonda ukulinganiswa kunye nokubeka iliso kwindalo ngokuguqula iimpawu zesignali yokubonakalayo. Umzekelo, ngokuguqula isigaba okanye ubukhulu bokukhanya, ii-gyroscopes ze-fiber optic, ii-fibre optic pressure sensors, njl.njl. zinokufezekiswa
3. Ugcino kunye nokucubungula i-Optical: Ii-Optical modulators zisetyenziselwa ukugcina i-optical kunye nezicelo zokucubungula i-optical. Kwimemori ye-optical, ii-optical modulators zingasetyenziselwa ukubhala nokufunda ulwazi ngaphakathi nangaphandle kwe-optical media. Kwi-optical processing, i-optical modulator ingasetyenziselwa ukwenza, ukucoca, ukuguqula kunye nokunciphisa imiqondiso ye-optical
4. Imifanekiso ye-Optical: ii-optical modulators zingasetyenziselwa ukuguqula isigaba kunye nobukhulu bomsebe wokukhanya, ngaloo ndlela zitshintsha iimpawu zomfanekiso kwimifanekiso ye-optical. Umzekelo, i-light field modulator inokusebenzisa i-two-dimensional phase modulation ukutshintsha ubude be-focal kunye nobunzulu be-focus ye-beam
5. Ulawulo lwengxolo yokukhanya: I-optical modulator inokulawula ubukhali kunye nokuphindaphinda kokukhanya, ngaloo ndlela inciphisa okanye icinezele ingxolo yokukhanya kwinkqubo yokukhanya.
