LGS Substrate
Inkcazo
I-LGS ingasetyenziselwa ukwenza izixhobo ze-piezoelectric kunye ne-electro-optical.Ineempawu eziphezulu zepiezoelectric.I-coefficient yokudibanisa i-electromechanical iphindwe kathathu ye-quartz, kwaye iqondo lokushisa lokutshintsha kwesigaba liphezulu (ukusuka kwiqondo lokushisa ukuya kwindawo yokunyibilika kwe-1470 ℃).Ingasetyenziselwa kwi-saw, i-BAW, inzwa yokushisa ephezulu kunye namandla aphezulu, izinga lokuphindaphinda i-electro-optic Q-switch.

LGS Substrate Definition
I-LGS (i-Lithium Gallium Silicate) i-substrate ibhekisela kuhlobo oluthile lwe-substrate yezinto eziqhelekileyo ezisetyenziselwa ukukhula kweefilimu ezinqabileyo ze-crystal enye.Ii-substrates ze-LGS zisetyenziswa ikakhulu kwimimandla yezixhobo ze-electro-optic kunye ne-acousto-optic, ezifana neziguquli zefrikhwensi, iimodyuli zokukhanya, izixhobo zamaza amaza angaphezulu, njl.
I-LGS substrates iquka i-lithium, i-gallium, kunye ne-silicate ion kunye nezakhiwo ezithile ze-crystal.Olu lwakhiwo lukhethekileyo lunika ii-LGS substrates ezifanelekileyo ze-optical kunye nezakhiwo ezibonakalayo kwiintlobo ezahlukeneyo zezicelo.Ezi substrates zibonisa izalathisi eziphezulu ze-refractive, ukufunxwa kokukhanya okuphantsi, kunye nokubonakala okugqwesileyo okugqwesileyo kuluhlu olusondeleyo lwe-infrared wavelength.
Ii-substrates ze-LGS zifaneleke ngokukodwa ukukhula kwezakhiwo zefilimu ezibhityileyo njengoko zihambelana neendlela ezahlukeneyo zokubeka ezifana ne-molecular beam epitaxy (MBE) okanye iindlela zokukhula kwe-epitaxial ezifana ne-chemical vapor deposition (CVD).
Iimpawu ezithile ze-LGS substrates, ezifana neepropathi ze-piezoelectric kunye ne-electro-optic, zizenza zilungele ukwenza izixhobo ezifuna iipropathi ze-voltage ezilawulwa yi-voltage okanye zivelise amaza e-acoustic angaphezulu.
Isishwankathelo, i-LGS substrates luhlobo oluthile lwe-substrate material esetyenziselwa ukukhulisa ifilimu enye-crystal encinci yezicelo kwizixhobo ze-electro-optic kunye ne-acousto-optic.Ezi substrates zineempawu ezinqwenelekayo ze-optical kunye nezinto ezibonakalayo ezenza ukuba zifaneleke kwiintlobo ezahlukeneyo ze-optical kunye ne-electronic applications.
