Ukwethulwa okufushane kobuchwepheshe be-Laser Modulator

Ukwethulwa okufushane kwe-laserimbebulaubuchwepheshe
I-laser igagasi elijwayelekile le-electromagnetic le-electromagnetic, ngenxa yokuhlangana kwayo okuhle, njengamagagasi endabuko we-electromagnetic (anjenge asetshenzisiwe emsakazweni nawamabonakude), njengegagasi lenkampani yenethiwekhi ukuze adlulise imininingwane. Inqubo yokulayisha imininingwane e-laser ibizwa ngokuthi yi-movie, futhi idivaysi eyenza le nqubo ibizwa ngokuthi yi-modulator. Kule nqubo, i-laser isebenza njengomthwali, ngenkathi isibonakaliso esivame kakhulu sokudlulisa imininingwane ibizwa ngokuthi isiginali elungisiwe.
Ukushintshwa kwe-laser kuvame ukuhlukaniswa kwaba ukuguquguquka kwangaphakathi kwangaphakathi kwezindlela ezimbili zokushintshana ngezindlela ezimbili. Ukushintshwa kwangaphakathi: Kubhekiswa ekuguqukeni kwenqubo ye-Laser Oscillation, okungukuthi, ngokuguqula isibonakaliso sokushintsha amapharamitha we-Oscillation e-laser. Kunezindlela ezimbili zokushintshashintsha kwangaphakathi: 1. Lawula ngokuqondile ukuhanjiswa kwamandla okupompa kwe-laser ukuze uguqule ubukhulu bokukhishwa kwe-laser. Ngokusebenzisa isiginali ukulawula ukuhlinzekwa kwamandla we-laser, amandla okukhipha ama-laser angalawulwa yisiginali. 2 Inzuzo yokuguqulwa kwangaphakathi ukuthi ukusebenza kahle kokushintshanisa kuphakeme, kepha ukungahambi kahle yilokho ngoba i-modulator itholakala emgodini, izokukhulisa ukulahleka emgodini, futhi i-bandwidth yesimodeli izophinde ikhawulelwe yi-passband ye-resonator. Ukushintshwa kwangaphandle: kusho ukuthi ngemuva kokwakhiwa kwe-laser, i-modulator ibekwa endleleni ye-laser ngaphandle kwe-laser, futhi izici zomzimba ze-modulator ziguqulwa ngesizinda esilungisiwe, futhi lapho i-laser idlula esisinjiniyela, igagasi elithile legagasi elikhanyayo lizolungiswa. Izinzuzo zokuguqulwa kwangaphandle ukuthi amandla okukhipha e-laser awathinteki kanti umkhawulokudonsa wesilawuli akanqunyelwe yi-passband ye-resonator. Okubi kakhulu ukuguquguquka okuphansi kwentukuthelo.
Ukushintshwa kwe-laser kungahlukaniswa ku-Amplitude Modralion, ukuguquguquka imvamisa, ukuguquguquka kwesigaba kanye nokuguquguquka kokuqina ngokuya ngezindawo zayo zokushintsha. 1, Ukushintshwa kwe-Amplitutution: Ukuguquguquka kwe-Amplitutution yi-oscillation ukuthi amplitude kangaphakathi eshintsha nomthetho wesiginali elungisiwe. 2, Ukushintshashintsha Kwemvamisa: Ukushintsha isiginali ukushintsha imvamisa ye-laser oscillation. 3, Ukushintshwa kwesigaba: Ukushintsha isiginali ukushintsha isigaba se-Laser Oscillation Laser.

I-Electro-Optical Intensity Modulator
Umgomo wokuguquguquka kokuqina kwe-electro-optic ukubona ukuguquguquka okuphezulu ngokuya ngomgomo wokuphazamiseka wokukhanya okukhanyayo ngokusebenzisa i-electro-optic umphumela wekristali. Umphumela we-electro-optical wekristalu ubhekisa kwisimo senkomba evulekayo ngaphansi kwendlela yenkundla kagesi yangaphandle, okuholela ekuhluphekeni kwenkambu ye-polarizal, ukuze isimo se-polarization sishintsha.

I-electro-optic isigaba modulator
I-Electro-angle ye-Laser Oscillation iguqulwe nguMthetho Wokuguqula Isiginali.

Ngokungeziwe ku-Electro-optic yokushintshana ngokuguquguquka kwe-electro-optic, kunezindlela eziningi ze-laser modulators, njenge-transverse electro-optic modulator, i-acctro-optic modulator, i-acousto-optic modulator, i-modulator ye-acousto-optic, i-magnetooptic modulator, i-spatial light modulator.
