Uburebure bwumucyo mwinshi kumpapuro

Uburebureisoko yumucyoku rupapuro

Amashanyarazi meza ni inzira byanze bikunze yo gukomeza Amategeko ya Moore, yabaye ubwumvikane bw’amasomo n’inganda, irashobora gukemura neza ibibazo by’umuvuduko n’amashanyarazi ahura n’ibikoresho bya elegitoroniki, byitezwe ko bizahindura ejo hazaza h’ubumenyi bw’ubwenge na ultra-yihutaitumanaho ryiza. Mu myaka yashize, iterambere ryingenzi mu ikoranabuhanga muri fotonike ishingiye kuri silikoni yibanda ku iterambere rya chip urwego rwa microcavity soliton optique yumurongo wa kombine, ishobora kubyara imirongo imwe ihuriweho na mikorobe ya optique. Kubera ibyiza byayo byo kwishyira hamwe, kwaguka kwinshi no gusubiramo inshuro nyinshi, chip urwego microcavity soliton yumucyo isoko ishobora gukoreshwa muburyo bunini bwo gutumanaho, spekitroscopi,microwave Photonics, gupima neza nizindi nzego. Muri rusange, uburyo bwo guhindura imikorere ya microcavity imwe ya soliton optique yumurongo wa tombora akenshi igarukira kubipimo bijyanye na microcavity optique. Munsi ya pompe yihariye, imbaraga zisohoka za microcavity imwe soliton optique yumurongo wa combre akenshi iba mike. Kwinjiza sisitemu yo hanze ya optique amplification byanze bikunze bizagira ingaruka ku kimenyetso cyerekana urusaku. Kubwibyo, ibishushanyo mbonera bya microcavity soliton optique yumurongo wa tombora byahindutse gukurikirana uyu murima.

Vuba aha, itsinda ryubushakashatsi muri Singapuru ryateye intambwe yingenzi mubijyanye n’umucyo utanga urumuri rwinshi kumpapuro. Itsinda ry’ubushakashatsi ryateguye chip ya microcavity chip hamwe na tekinike iringaniye, yagutse kandi hafi ya zeru ikwirakwizwa, kandi ipakira neza chip optique hamwe no guhuza impande zombi (igihombo kiri munsi ya 1 dB). Dushingiye kuri optique ya microcavity chip, ingaruka zikomeye za termo-optique muri microcavity optique zitsindwa na tekiniki ya tekinike yo kuvoma kabiri, kandi urumuri rwinshi rwumucyo utanga umusaruro ushimishije. Binyuze muri sisitemu yo kugenzura ibitekerezo, sisitemu nyinshi-yumurongo wa soliton sisitemu irashobora gukora neza mumasaha arenze 8.

Ibisohoka biva mu mucyo biva hafi ya trapezoidal, igipimo cyo gusubiramo ni nka 190 GHz, igorofa iringaniye igera kuri 1470-1670 nm, uburinganire bwa hafi 2.2 dBm (gutandukana bisanzwe), kandi intera igaragara ifite 70% muri byose urutonde rwerekana, rutwikiriye itsinda rya S + C + L + U. Ibisubizo byubushakashatsi birashobora gukoreshwa mubushobozi buhanitse bwa optique ihuza kandi murwego rwo hejuruoptiquesisitemu yo kubara. Kurugero, muri sisitemu nini yerekana itumanaho ryerekana uburyo bushingiye kuri microcavity soliton ibimamara, itsinda ryikomatanya ryitsinda rifite itandukaniro rinini ryingufu zihura nikibazo cya SNR nkeya, mugihe isoko ya soliton hamwe nibisohoka byoroshye bishobora gutsinda iki kibazo kandi bigafasha kunoza u SNR muburyo buboneye bwo gutunganya amakuru, ifite akamaro gakomeye mubuhanga.

Igikorwa cyiswe “Flat soliton microcomb source,” cyasohowe nk'impapuro zitwikiriye muri Opto-Electronic Science mu rwego rwa “Digital and Intelligent Optics”.
