Lithium niobate inonziwo optical silicon. Pane chirevo chinoti "lithium niobate ndeyekutaurirana kwemaziso izvo silicon ndeye semiconductors." Kukosha kwesilicon mukuchinja kwemagetsi, saka chii chinoita kuti indasitiri ive netariro pamusoro pelithium niobate zvinhu?
Lithium niobate (LiNbO3) inozivikanwa se "optical silicon" muindasitiri. Pamusoro pezvakanakira zvechisikigo zvakaita sekugadzikana kwemuviri uye kemikari, hwindo rakafara rakajeka (0.4m ~ 5m), uye hombe electro-optical coefficient (33 = 27 pm/V), lithium niobate imhando yekristaro ine yakawanda mbishi zvinyorwa uye mutengo wakaderera. Inoshandiswa zvakanyanya mumasefa epamusoro ekuita, electro-optical zvishandiso, holographic storage, 3D holographic display, nonlinear optical devices, optical quantum communication nezvimwe zvakadaro. Mundima yekukurukurirana kwemaziso, lithium niobate inonyanya kuita basa rekugadzirisa chiedza, uye yave iri chigadzirwa chikuru mune yazvino high-speed electro-optical modulator (Eo Modulator) musika.
Parizvino, kune matatu makuru matekinoroji ekugadzirisa mwenje muindasitiri: electro-optical modulators (Eo Modulator) yakavakirwa pasilicon mwenje, indium phosphide uye.lithium niobatezvinhu platforms. Silicon optical modulator inonyanya kushandiswa mupfupi-renji data kutaurirana transceiver modules, indium phosphide modulator inonyanya kushandiswa mupakati-range uye yakareba-range optical network transceiver modules, uye lithium niobate electro-optical modulator (Eo Modulator) inonyanya kushandiswa mukureba-range kutaurirana uye single-0b0-cowaverent network 1G0b0-cowaverent network. ultra-high-speed data centers. Pakati peatatu ari pamusoro apa ekupedzisira-yepamusoro-soro modulator zvinhu mapuratifomu, iyo yakaonda firimu lithium niobate modulator yakabuda mumakore achangopfuura ine bandwidth mukana wekuti zvimwe zvinhu hazvigone kuenderana.
Lithium niobate imhando ye inorganic substance, chemical formulaLiNbO3, is a negative crystal, ferroelectric crystal, polarized lithium niobate crystal ine piezoelectric, ferroelectric, photoelectric, nonlinear optics, thermoelectric nezvimwe zvinhu zvezvinhu, panguva imwe chete ne photorefractive effect. Lithium niobate crystal ndeimwe yeanonyanya kushandiswa zvakanyanya inorganic zvinhu, yakanaka piezoelectric simba rekuchinjana zvinhu, ferroelectric material, electro-optical material, lithium niobate se electro-optical material mu optical communication inoita basa mukureruka modulation.
Iyo lithium niobate zvinhu, inozivikanwa se "optical silicon", inoshandisa ichangoburwa micro-nano process yekuputira iyo silicon dioxide (SiO2) layer pasilicon substrate, sunga iyo lithium niobate substrate patembiricha yepamusoro kuti ivake nzvimbo yekutsemura, uye pakupedzisira kubvisa iyo lithium niobate firimu. Iyo yakagadziridzwa firimu yakaonda lithium niobate modulator ine zvakanakira kuita kwepamusoro, mutengo wakaderera, saizi diki, kugadzirwa kwehuwandu, uye kuenderana neCMOS tekinoroji, uye imhinduro yemakwikwi ehupamhi hwepamusoro-soro yekubatanidza mune ramangwana.
Kana iyo yepakati yemagetsi revolution yakatumidzwa zita resilicon zvinhu izvo zvakaita kuti zviitike, ipapo iyo photonics revolution inogona kuteverwa kune zvinhu lithium niobate, inozivikanwa se "optical silicon" lithium niobate chinhu chisina ruvara chakajeka chinosanganisa mafotorefractive mhedzisiro, nonlinear mhedzisiro, electro-optical mhedzisiro, acousto-optical mhedzisiro, piezoelectric mhedzisiro uye thermal mhedzisiro. Zvizhinji zvezvivakwa zvayo zvinogona kudzorwa nekristaro kuumbwa, element doping, valence state control uye zvimwe zvinhu. Inoshandiswa zvakanyanya kugadzirira optical waveguide, optical switch, piezoelectric modulator,electro-optical modulator, yechipiri harmonic jenareta, laser frequency multiplier uye zvimwe zvigadzirwa. Muindasitiri yekukurukurirana yemaziso, modulators imusika wakakosha wekushandisa welithium niobate.
