Iqhaza lefilimu elincanyana le-lithium niobate ku-electro-optic modulator

Indima yefilimu emincane ye-lithium niobate inI-Electro-Optic Modulator
Kusukela ekuqaleni kwemboni kuze kube manje, amandla okuxhumana nge-fiber eyodwa akhuphuke ngezigidi zezikhathi, futhi inani elincane locwaningo olusikiwe selwedlule amashumi ezigidi zezikhathi. I-Lithium niobate yadlala indima enkulu phakathi kwemboni yethu. Ezinsukwini zokuqala zokuxhumana kwe-fiber okubonakalayo, ukuguqulwa kwesiginali ye-optical kwahlelwa ngqo kui-laser. Le ndlela yokushintshashintsha yamukelekile ku-bandwidth ephansi noma izinhlelo ezifushane zebanga. Ngokushintshashintsha kwesivinini esiphezulu kanye nezicelo zebanga elide, kuzoba nomkhawulokudonsa olwanele futhi isiteshi sokuhambisa sibiza kakhulu ukufeza izicelo zebanga elide.
Maphakathi nokukhulumisana kwe-fiber optical, ukuguquguquka kwesiginali kushesha futhi kusheshe ukubhekana nokwanda kwamandla okuxhumana, futhi imodi yokushintshanisa yesiginali ye-Optical iqala ukuhlukanisa, futhi izindlela zokushintshana ezahlukahlukene zisetshenziswa ekuxhumaneni nebanga elide kanye ne-trunk trunkt. Ukuguqulwa okuqondile okubiza okuphansi kusetshenziswa ekuxhumaneni nebanga eliphansi, kanye ne- "electro-optumulator" ehlukile "esetshenzisiwe ku-trunk ye-trunk yebanga elide, ehlukaniswe ne-laser.
I-Electro-Optic Modulator isebenzisa isakhiwo sokuphazanyiswa kweMachZender ukuguqula isinali, ukukhanya kungugesi we-electromagnetic, i-electromagnetic wave atformate angferent aphazamisa imvamisa ezinzile, isigaba kanye ne-polarization. Imvamisa sikhuluma ngegama, elibizwa ngokuthi ama-fringes aphazamisayo, amafreyimu akhanyayo futhi amnyama, okugqamile yindawo yokuphazamiseka kwe-electromagnetic kuthuthukiswa, kumnyama indawo lapho ukuphazamiseka kwe-electromagnetic kubangela ukuba buthaka. Ukuphazanyiswa kweMahazender kuwuhlobo lwe-Interferometer ngesakhiwo esikhethekile, okungukuthi umphumela wokuphazamiseka olawulwa ngokulawula isigaba sogongolo olufanayo ngemuva kokuhlukanisa ugongolo. Ngamanye amagama, umphumela wokuphazanyiswa ungalawulwa ngokulawula isigaba sokuphazanyiswa.
I-Lithium iniobate lokhu okuqukethwe kusetshenziswa ekuxhumaneni kwe-fiber okubonakalayo, okungukuthi, kungasebenzisa izinga le-voltage (isinambiso kagesi) ukulawula isigaba sokukhanya, ukufezekisa ukushintshwa kwesibonakaliso sokukhanya, okuwubudlelwano phakathi kwe-electro-optical modulator kanye ne-lithium niobate. Isimonyo sethu sibizwa ngokuthi i-electro-optic modulator, okudinga ukubheka bobabili ubuqotho besiginali kagesi kanye nekhwalithi yokushintshanisa yesiginali ye-optical. Amandla wesiginali kagesi we-Indium Phosphide kanye ne-Silicon Photonics kungcono kunaleso se-Lithium Niobate, futhi amandla wesiginali we-Optical abuthakathaka kancane kepha angasetshenziswa, okudala indlela entsha yokubamba ithuba lemakethe.
Ngaphezu kwezici zabo ezinhle kakhulu zikagesi, i-Indium Phosphide kanye ne-Silicon Photonics zinezinzuzo ze-miniaturization kanye nokuhlanganiswa ukuthi i-lithium niobate ayinayo. I-Indium Phosphide incane kune-Lithium Niobate futhi ine-degree ehlanganisiwe ephezulu, kanye nama-Silicon Photon amancane kune-Indium Phosphide futhi abe ne-degree ehlanganisiwe ephezulu. Ikhanda le-lithium niobate njengeimbebulaInde kabili njenge-Indium Phosphide, futhi ingaba yimodeli kuphela futhi ayikwazi ukuhlanganisa eminye imisebenzi.
Njengamanje, i-Electro-Optical Modulator ifake inkathi yezinga elingamatshe ayizigidi eziyizinkulungwane eziyikhulu, (i-128G lingu-128 billion), futhi i-lithium niobate iphinde ifake empini ukuhlanganyela kulo mncintiswano, futhi iholele ekungeneni imakethe yezinga lama-250 billion. Kwi-Lithium Niobate yokuthola le makethe, kuyadingeka ukuhlaziya ukuthi yini i-Indium phosphide ne-silicon photon, kepha i-lithium niobate ayisebenzi. Lokho amandla kagesi, ukuhlanganiswa okuphezulu, okuncane.
Ukushintshwa kwe-lithium niobate kulele ngama-engeli amathathu, i-angle yokuqala yindlela yokuthuthukisa amandla kagesi, i-angle yesibili yindlela yokwenza ukuthuthukisa ukuhlanganiswa, ne-angle yesithathu ukuthi ungathandana kanjani. The solution to these three technical angles requires only one action, that is, to thin film the lithium niobate material, take out a very thin layer of lithium niobate material as an optical waveguide, you can redesign the electrode, improve the electrical capacity, improve the bandwidth and modulation efficiency of the electrical signal. Ngcono ikhono kagesi. Le filimu nayo ingahle ifakwe kwi-Silicon Wafer, ukufezekisa ukuhlanganiswa okuxubile, i-lithium niobate njenge-modulator, i-silicon photon ukuhlanganiswa, ukuhlanganiswa kwefilimuni ye-silicon ye-silicon, ukuhlanganisa okuncane.
Esikhathini esizayo esiseduze, i-Electro-Optical Modulator isizongena kwi-ENA yezinga elingu-200 billion, i-Indiium Phosphide kanye ne-Sithicon Photons liyabonakala ngokwengeziwe, futhi inzuzo ye-lithicon niobate ithuthukisa ukungathandeki, futhi inzuzo ye-lithium nithium ye-modulator, futhi imboni ye-lithium igxile kule modi " niobate ", lokho, ifilimu elincanyanaI-Lithium niobate Modulator. Le yindima yefilimu elincanyana le-lithium niobate emkhakheni we-Electro-Optical Modulators.
