LGS Substrate Definition
LGS (Lithium Gallium Silicate) substrate yana nufin takamaiman nau'in kayan da aka saba amfani da shi don haɓakar fina-finai na kristal guda ɗaya.LGS substrates ana amfani da yafi a cikin filayen electro-optic da acousto-optic na'urorin, kamar mita converters, na gani modulators, surface acoustic kalaman na'urorin, da dai sauransu.
Abubuwan LGS sun ƙunshi lithium, gallium, da silicate ions tare da takamaiman sifofi na crystal.Wannan na musamman abun da ke ciki yana ba LGS substrates ingantattun kaddarorin gani da na zahiri don aikace-aikace iri-iri.Waɗannan ɓangarorin suna baje kolin indices masu ɗaukar nauyi, ƙarancin ɗaukar haske, da ingantaccen haske a bayyane zuwa kewayon tsayin infrared na kusa.
LGS substrates sun dace musamman don haɓaka sifofin fina-finai na bakin ciki saboda sun dace da dabaru daban-daban na jita-jita kamar su molecular beam epitaxy (MBE) ko hanyoyin ci gaban epitaxial kamar bayanan tururin sinadarai (CVD).
Takamaiman kaddarorin LGS, kamar piezoelectric da kaddarorin lantarki-optic, sun sa su dace don kera na'urorin da ke buƙatar kaddarorin gani mai sarrafa wutar lantarki ko haifar da raƙuman sauti na saman.
A taƙaice, LGS substrates sune takamaiman nau'in kayan da ake amfani da su don haɓaka fina-finai na bakin ciki guda-crystal don aikace-aikace a cikin na'urorin lantarki-optic da acousto-optic.Waɗannan kayan aikin suna da kyawawan kaddarorin gani da na zahiri waɗanda ke sa su dace da aikace-aikacen gani da lantarki iri-iri.
