I-LN–Q Itshintshe I-Crystal Umfanekiso Obonisiweyo

I-LN–Q Ikristale etshintshileyo

Inkcazelo emfutshane:

I-LiNbO3 isetyenziswa ngokubanzi njenge-electro-optic modulators kunye ne-Q-switches ye-Nd: YAG, Nd: YLF kunye ne-Ti: i-laser ye-Sapphire kunye ne-modulators ye-fiber optics.Itheyibhile ilandelayo idwelisa iinkcukacha zekristale ye-LiNbO3 eqhelekileyo esetyenziswe njenge-Q-switch kunye ne-modulation ye-EO eguquguqukayo.

Ingcaciso yeMveliso

Ukukhanya kusasazeka kwi-z-axis kunye nebala lombane lisebenza kwi-x-axis.I-electro-optic coefficients ye-LiNbO3 zezi: r33 = 32 pm / V, r31 = 10 pm / V, r22 = 6.8 pm / V kwi-frequency ephantsi kunye ne-r33 = 31 pm / V, r31 = 8.6 pm / V, r22 = 3.4 pm/V kumaza ombane aphezulu.Umbane wesiqingatha-amaza ombane: Vπ=λd/(2no3r22L), rc=(ne/no)3r33-r13.LiNbO3 ikwayikristale elungileyo yeacousto-optic kwaye isetyenziselwa iwave ye-acoustic wave (SAW) kunye ne-AO modulators.I-CASTECH ibonelela ngeekristale ze-acoustic (SAW) zebakala le-LiNbO3 kwii-wafers, njengoko-cut boules, izinto ezigqityiweyo kunye nezinto ezenziwe ngokwezifiso.
