I-LN–Q Ishintshe Isithombe Esifakiwe Se-Crystal

I-LN–Q Ishintshe I-Crystal

Incazelo emfushane:

I-LiNbO3 isetshenziswa kabanzi njengama-modulators e-electro-optic kanye nama-Q-switches e-Nd:YAG, Nd:YLF kanye ne-Ti:Sapphire lasers kanye nama-modulators for fibre optics. Ithebula elilandelayo libonisa imininingwane yekristalu ye-LiNbO3 evamile esetshenziswa njenge-Q-switch ene-transverse EO modulation.

Ukukhanya kubhebhetheka ku-z-eksisi kanye nenkambu kagesi kusebenza ku-x-eksisi. Ama-coefficients we-electro-optic we-LiNbO3 yilawa: r33 = 32 pm/V, r31 = 10 pm/V, r22 = 6.8 pm/V kumafrikhwensi aphansi futhi r33 = 31 pm/V, r31= 8.6 pm/V, r22pm = 3.4 imvamisa kagesi I-voltage enguhhafu-wave: Vπ=λd/(2no3r22L), rc=(ne/no)3r33-r13.LiNbO3 iphinde ibe yikristalu enhle ye-acousto-optic futhi isetshenziselwa i-surface acoustic wave (SAW) wafer namamodulators we-AO. I-CASTECH inikeza amakristalu e-acoustic (SAW) ebanga le-LiNbO3 kuma-wafers, ama-boules as-cut, izinto eziqediwe nezinto ezenziwe ngokwezifiso.
