Ke engmodulator ea mohato
Modulator ea Mokhahlelo ke modulator ea optical e ka laolang mohato oa lebone la laser. Mefuta e tloaelehileng ea li-modulator tsa mohato ke tse thehiloeng lebokoseng la Pockelsli-modulator tsa electro-opticle di-modulator tsa kristale ya mokelikeli, tse ka boelang tsa nka monyetla ka diphetoho tsa index ya refractive ya faeba ya mocheso kapa diphetoho tsa bolelele, kapa ka ho otlolla ho fetola bolelele. Di-modulator tse fapaneng tsa phase di sebediswa lefapheng la di-optics tse kopaneng, moo lesedi le fetotsweng le hasanang ka hara leqhubu la maqhubu.
Litšobotsi tsa bohlokoa tsa li-modulator tsa mohato li kenyelletsa: Boholo ba modulation ea mohato (e khethollang index ea modulation le matla a amanang le lehlakore) e hloka bandwidth ea modulation ea motlakase oa drive (sebaka sa maqhubu a modulation),modulator ea electro-opticale ka tatellano ea GHz, 'me sesebelisoa se sebelisang phello ea mocheso kapa thepa ea kristale ea mokelikeli se tlase haholo ho feta bandwidth ea ts'ebetso ea lesoba la sesebelisoa. E fokotsa radius ea mahlaseli a moriti oa moriti o fetotsoeng Litekanyo tsa kantle tsa sesebelisoa Thepa ena e fapana haholo bakeng sa mefuta e fapaneng ea li-modulator tsa mekhahlelo. Ka hona, li-modulator tse fapaneng tsa mekhahlelo li hloka ho sebelisoa lits'ebetsong tse fapaneng tsa ts'ebetso.
Mehlala ea lits'ebetso tsa modulator ea mohato e kenyelletsa: Modulator ea mohato ka har'a resonator ea laser ea laser ea maqhubu a le mong e ka sebelisoa bakeng sa ho lokisa bolelele ba wavelength, kapa ho notlela mokhoa o sebetsang (FM mode-locking) oa laser ho hlophisa khanya haeba e na le matla a modulation a itekanetseng, e ka sebelisoa mokhoeng oa ho tsitsisa maqhubu a laser, mohlala, Mokhoa oa Pell-Drever-Hall o hloka li-modulator tsa mohato lisebelisoa tse ngata tsa tekanyo ea li-spectral tsa interferometer, hangata li sebelisa matšoao a ho khanna nako le nako. Litekanyo tse ling li hloka li-comb tsa maqhubu, tse fumanoang ka ho kenya khanya ea maqhubu a le mong ka har'a modulator ea mohato. Tabeng ena, modulation ea mohato hangata e hloka ho ba matla, e le hore u ka fumana lihlopha tse ngata tsa lehlakore. Ho transmitter ea data ea sistimi ea puisano ea fiber ea optical, modulator ea mohato e ka sebelisoa ho khetholla tlhahisoleseling e fetisoang. Mohlala, mokhoa oa ho kenya senotlolo sa phase-shift oa sebelisoa.
