Karolo ea filimi e tšesaane ea lithium niobate homodulator ea electro-optic
Ho tloha qalong ea indasteri ho fihlela joale, bokhoni ba puisano ea faeba e le 'ngoe bo eketsehile ka makhetlo a limilione, 'me palo e nyane ea lipatlisiso tsa sejoale-joale e fetile makhetlo a limilione tse mashome. Lithium niobate e bapetse karolo e kholo bohareng ba indasteri ea rona. Matsatsing a pele a puisano ea faeba ea optical, phetoho ea lets'oao la optical e ne e lokisoa ka kotloloho holaserMokhoa ona oa ho fetola molumo oa amoheleha lits'ebetsong tsa bandwidth e tlase kapa tsa sebaka se sekhutšoanyane. Bakeng sa lits'ebetso tsa ho fetola molumo ka lebelo le phahameng le tsa sebaka se selelele, ho ke ke ha e-ba le bandwidth e lekaneng 'me kanale ea phetisetso e theko e boima haholo ho fihlela lits'ebetso tsa sebaka se selelele.
Bohareng ba puisano ea faeba ea optical, phetoho ea lets'oao e potlakile le ho feta ho fihlela keketseho ea bokhoni ba puisano, 'me mokhoa oa phetoho ea lets'oao la optical o qala ho arohana, 'me mekhoa e fapaneng ea phetoho e sebelisoa marang-rang a sebaka se sekhutšoanyane le marang-rang a sebaka se selelele. Phetoho e tobileng e theko e tlase e sebelisoa marang-rang a sebaka se sekhutšoanyane, 'me "modulator ea electro-optic" e arohaneng e sebelisoa marang-rang a sebaka se selelele, e arotsoeng ho laser.
Modulator ea electro-optic e sebelisa sebopeho sa tšitiso ea Machzender ho fetola lets'oao, leseli ke leqhubu la motlakase, tšitiso ea maqhubu a motlakase e tsitsitseng e hloka maqhubu a taolo a tsitsitseng, mohato le polarization. Hangata re bua ka lentsoe, le bitsoang li-fringe tsa tšitiso, li-fringe tsa leseli le lefifi, sebaka se khanyang moo tšitiso ea motlakase e ntlafatsoang teng, lefifi ke sebaka seo tšitiso ea motlakase e bakang matla ho fokola. Tšitiso ea Mahzender ke mofuta oa interferometer e nang le sebopeho se ikhethileng, e leng phello ea tšitiso e laoloang ke ho laola mohato oa lehlaseli le tšoanang kamora ho arola lehlaseli. Ka mantsoe a mang, sephetho sa tšitiso se ka laoloa ka ho laola mohato oa tšitiso.
Lithium niobate thepa ena e sebediswa puisanong ya faeba ya optical, ke hore, e ka sebedisa boemo ba motlakase (letshwao la motlakase) ho laola mokgahlelo wa lesedi, ho fihlella modulator ya letshwao la lesedi, e leng kamano pakeng tsa modulator ya electro-optical le lithium niobate. Modulator ya rona e bitswa modulator ya electro-optic, e hlokang ho nahana ka botshepehi ba letshwao la motlakase le boleng ba modulator ya letshwao la optical. Bokgoni ba letshwao la motlakase ba indium phosphide le silicon photonics bo betere ho feta ba lithium niobate, mme bokgoni ba letshwao la optical bo fokola hanyane empa bo ka boela ba sebediswa, e leng se hlahisang tsela e ntjha ya ho nka monyetla wa mmaraka.
Ntle le thepa ea tsona e ntle ea motlakase, indium phosphide le silicon photonics li na le melemo ea miniaturization le integration eo lithium niobate e se nang eona. Indium phosphide e nyane ho feta lithium niobate 'me e na le tekanyo e phahameng ea integration, 'me silicon photons li nyane ho feta indium phosphide 'me li na le tekanyo e phahameng ea integration. Hlooho ea lithium niobate e lemodulatore telele habeli ho feta indium phosphide, 'me e ka ba modulator feela 'me e ke ke ea kopanya mesebetsi e meng.
Hona jwale, modulator ya electro-optical e kene nakong ya sekgahla sa matshwao a dibilione tse 100, (128G ke dibilione tse 128), mme lithium niobate e boetse e kene ntweng ya ho nka karolo tlholisanong, mme e tshepa ho etella pele nako ena nakong e tlang e haufi, e etella pele ho kena mmarakeng wa sekgahla sa matshwao a dibilione tse 250. Hore lithium niobate e hape mmaraka ona, ho hlokahala ho sekaseka seo indium phosphide le silicon photons di nang le sona, empa lithium niobate ha e na sona. Ke bokgoni ba motlakase, kopanyo e phahameng, miniaturization.
Phetoho ea lithium niobate e lutse ka likhutlo tse tharo, Angle ea pele ke mokhoa oa ho ntlafatsa bokhoni ba motlakase, Angle ea bobeli ke mokhoa oa ho ntlafatsa kopanyo, 'me Angle ea boraro ke mokhoa oa ho etsa hore e be nyane. Tharollo ea likhutlo tsena tse tharo tsa tekheniki e hloka ketso e le 'ngoe feela, ke hore, ho etsa filimi ea thepa ea lithium niobate ka mokhoa o fokolang, ho ntša lera le lesesaane haholo la thepa ea lithium niobate e le tataiso ea maqhubu a optical, u ka etsa moralo oa electrode bocha, ua ntlafatsa bokhoni ba motlakase, ua ntlafatsa bandwidth le katleho ea modulation ea lets'oao la motlakase. Ntlafatsa bokhoni ba motlakase. Filimi ena e ka boela ea hokeloa ho silicon wafer, ho fihlela kopanyo e tsoakiloeng, lithium niobate e le modulator, karolo e setseng ea kopanyo ea silicon photon, bokhoni ba silicon photon miniaturization bo totobetse ho bohle, filimi ea lithium niobate le kopanyo e tsoakiloeng ea leseli la silicon, ntlafatsa kopanyo, miniaturization e fihletsoeng ka tlhaho.
Haufinyane, modulator ea electro-optical e se e tla kena mehleng ea sekhahla sa matšoao a limilione tse likete tse 200, bothata ba mahlo ba indium phosphide le silicon photons bo ntse bo totobala haholoanyane, 'me molemo oa mahlo oa lithium niobate o ntse o hlahella haholoanyane, 'me filimi e tšesaane ea lithium niobate e ntlafatsa bothata ba thepa ena e le modulator, 'me indasteri e shebane le "filimi e tšesaane ea lithium niobate", ke hore, filimi e tšesaane.modulator ea lithium niobateEna ke karolo ea lithium niobate e tšesaane ea filimi lefapheng la li-modulator tsa electro-optical.
