Kazoza ka moderi ya electro optique

Kazoza kaamashanyarazi ya optique

Modulator ya electro optique igira uruhare runini muri sisitemu ya optoelectronic igezweho, igira uruhare runini mubice byinshi kuva itumanaho kugeza kuri comptabilite mu kugenzura imiterere yumucyo. Uru rupapuro ruvuga uko ibintu bimeze, iterambere rigezweho hamwe niterambere rya kazoza ka tekinoroji ya electro optique

Igishushanyo 1: Kugereranya imikorere itandukanyemoderi nzizatekinoroji, harimo firime yoroheje ya lithium niobate (TFLN), modulator ya III-V yo kwinjiza amashanyarazi (EAM), moderi ya silicon na moderi ya moderi mubijyanye no gutakaza insimburangingo, umurongo mugari, gukoresha ingufu, ingano, hamwe nubushobozi bwo gukora.

Gakondo ya silicon ishingiye kuri electro optique modulator hamwe nimbibi zabo

Moderi yerekana amashanyarazi yerekana amashanyarazi yabaye ishingiro rya sisitemu yo gutumanaho optique mumyaka myinshi. Ukurikije ingaruka zo gukwirakwiza plasma, ibikoresho nkibi byateye intambwe ishimishije mumyaka 25 ishize, byongera igipimo cyo kohereza amakuru kubitatu byubunini. Modulator igezweho ishingiye kuri silicon irashobora kugera ku ntera ya 4 ya pulse amplitude modulation (PAM4) igera kuri 224 Gb / s, ndetse irenga 300 Gb / s hamwe na PAM8.

Nyamara, modulitori ishingiye kuri silicon ihura nimbogamizi zifatika zikomoka kumitungo. Iyo optique ya optique isaba igipimo cya baud irenga 200+ Gbaud, ubwinshi bwibi bikoresho biragoye guhaza ibyifuzo. Iyi mbogamizi ituruka ku miterere yihariye ya silikoni - impirimbanyi zo kwirinda gutakaza urumuri rwinshi mu gihe ukomeza gutwara ibintu bihagije bitera inyungu byanze bikunze.

Ubuhanga bugaragara bwa tekinoroji nibikoresho

Imipaka ya moderi gakondo ishingiye kuri silicon yatumye ubushakashatsi mubindi bikoresho hamwe na tekinoroji yo guhuza. Filime ntoya ya lithium niobate yabaye imwe muma platform atanga ibyiringiro kubisekuru bishya bya modulator.Filime yoroheje lithium niobate electro-optique modulatorkuzungura ibintu byiza biranga ubwinshi bwa lithium niobate, harimo: idirishya ryagutse rifite umucyo, coefficient nini ya electro-optique (r33 = 31 pm / V) umurongo wa selire Kerrs ingaruka irashobora gukora mumirongo myinshi yumuraba

Iterambere rya vuba muri tekinoroji ya lithium niobate itanga umusaruro ushimishije, harimo na modulator ikora kuri 260 Gbaud ifite igipimo cya 1.96 Tb / s kuri buri muyoboro. Ihuriro rifite ibyiza byihariye nka CMOS-ihuza imashini ya voltage na 3-dB ya 100 GHz.

Ikoreshwa rya tekinoroji

Iterambere rya moderi ya electro optique ifitanye isano rya hafi na porogaramu zigaragara mubice byinshi. Mu rwego rwubwenge bwubuhanga nibigo byamakuru,modulator yihutani ingenzi kubisekuru bizaza byimikoranire, kandi porogaramu yo kubara AI itwara ibyifuzo bya 800G na 1.6T byacomeka. Tekinoroji ya modulator nayo ikoreshwa kuri: kwant amakuru yo gutunganya neuromorphic computing Frequency modulated continuive wave (FMCW) lidar microwave Photon tekinoroji

By'umwihariko, firime yoroheje ya lithium niobate moderi ya electro-optique yerekana imbaraga muri moteri yo gutunganya optique yo kubara, itanga modulisiyo yihuta yihuta yihuta yiga imashini hamwe nubwenge bwubuhanga. Bene modulator zirashobora kandi gukora mubushyuhe buke kandi zirakwiriye kuri kwant-classique intera mumirongo irenze urugero.

Iterambere ryibisekuru bizakurikiraho moderi ya electro optique ihura nibibazo byinshi byingenzi: Igiciro cyumusaruro nubunini: moderi yoroheje ya lithium niobate modulators kuri ubu igarukira kuri mm 150 ya wafer, bigatuma ibiciro byiyongera. Inganda zigomba kwagura ubunini bwa wafer mugihe hagumye uburinganire bwa firime nubuziranenge. Kwishyira hamwe no gufatanya: Iterambere ryiza ryaabayobora cyanebisaba ubushobozi bwuzuye bwo gushushanya, burimo ubufatanye bwa optoelectronics hamwe nabashushanya chip ya elegitoronike, abatanga EDA, amasoko, ninzobere mu gupakira. Gukora ibintu bigoye: Mugihe ibikorwa bya silicon bishingiye kuri optoelectronics bitagoranye kuruta ibikoresho bya elegitoroniki bya CMOS byateye imbere, kugera kumikorere ihamye no gutanga umusaruro bisaba ubuhanga bukomeye nibikorwa byo gukora neza.

Bitewe n’iterambere rya AI hamwe n’ibintu bya geopolitiki, urwego rwakira ishoramari ryiyongera kuri guverinoma, inganda n’abikorera ku isi, bitanga amahirwe mashya y’ubufatanye hagati y’amasomo n’inganda kandi basezeranya kwihutisha udushya.
