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 zvezvinhu 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 mumapfupi-renji data kutaurirana transceiver modules, indium phosphide modulator inonyanya kushandiswa mune yepakati-range uye yakareba-range optical network network transceiver modules, uye lithium niobate electro-optical modulator (Eo Modulator) inonyanya kushandiswa mu. refu-range backbone network coherent communication uye single-wave 100/200Gbps 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 yazvino micro-nano process kupfungaira iyo silicon dioxide (SiO2) layer pasilicon substrate, sunga iyo lithium niobate substrate pakupisa kwepamusoro kuvaka nzvimbo yekutsemuka, uye pakupedzisira kupepeta. kubva pane 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 zvakaita kuti zvigoneke, ipapo iyo photonics revolution inogona kuteverwa kune zvinhu lithium niobate, inozivikanwa se "optical silicon" lithium niobate chinhu chisina ruvara chakajeka chinosanganisa photorefractive 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.
