Isoko y'urumuri rw'uburebure bwinshi ku rupapuro rurerure

Uburebure bw'amabara menshiisoko y'urumuriku rupapuro rurerure

Udupira tw’ikoranabuhanga ni inzira idashobora kwirindwa yo gukomeza itegeko rya Moore, byabaye nk’uko byemejwe n’inganda n’ibigo by’amashuri makuru, bishobora gukemura neza ibibazo by’umuvuduko n’ikoreshwa ry’amashanyarazi bihura natwo, kandi byitezwe ko bizahindura ahazaza h’ikoranabuhanga ry’ikoranabuhanga n’ikoranabuhanga ryihuse cyane.itumanaho ry'amasoMu myaka ya vuba aha, iterambere rikomeye mu ikoranabuhanga mu bijyanye na silicon-based photonics ryibanda ku iterambere rya chip level microcavity soliton optical frequency combs, zishobora gukora frequency combs zifite intera imwe binyuze muri microcavities optical. Kubera ibyiza byazo byo guhuza cyane, wide spectrum na high repetition frequency, chip level microcavity soliton light source ishobora gukoreshwa mu itumanaho rinini, spectroscopy,fotoniki za mikoroonde, gupima neza n'izindi nzego. Muri rusange, ubushobozi bwo guhindura imikorere ya microcavity single soliton optical frequency comb akenshi bugengwa n'ibipimo bireba microcavity optical. Mu gihe cy'ingufu za pompe runaka, imbaraga zo gusohora microcavity single soliton optical frequency comb akenshi ziba nke. Kwinjizwa kwa sisitemu yo kongera ingufu z'amashanyarazi hanze bizagira ingaruka ku gipimo cy'urusaku hagati y'ibimenyetso n'urusaku. Kubwibyo, imiterere ya spectral ya microcavity soliton optical frequency comb yabaye intego y'uyu murima.

Mu minsi ishize, itsinda ry’abashakashatsi muri Singapuru ryateye imbere cyane mu bijyanye n’urumuri rw’uburebure bwinshi ku mpapuro zigororotse. Itsinda ry’abashakashatsi ryakoze chip ya microcavity ya optique ifite spectrum yagutse kandi hafi ya zeru, kandi ipakiye neza chip ya optique hamwe n’uburyo bwo guhuza impande (igihombo cyo guhuza kiri munsi ya 1 dB). Hashingiwe kuri chip ya microcavity ya optique, ingaruka zikomeye za thermo-optical muri microcavity ya optique zitsindwa na gahunda ya tekiniki yo gupompa inshuro ebyiri, kandi isoko y’urumuri rw’uburebure bwinshi hamwe n’umusaruro wa flat spectral iraboneka. Binyuze muri sisitemu yo kugenzura ibitekerezo, sisitemu ya multi-wavelength soliton source ishobora gukora neza amasaha arenga 8.

Umusaruro wa spectral w'urumuri ni hafi trapezoidal, igipimo cyo gusubiramo ni hafi 190 GHz, spectrum ya flat ifata 1470-1670 nm, uburebure ni hafi 2.2 dBm (itandukaniro risanzwe), naho urwego rwa flat spectral rufata 70% by'urwego rwose rwa spectral, rukora S+C+L+U band. Ibisubizo by'ubushakashatsi bishobora gukoreshwa mu guhuza optique ifite ubushobozi bwo hejuru no mu buryo bwo hejuru.itara ry'amasoSisitemu zo kubara. Urugero, muri sisitemu yo kwerekana itumanaho rifite ubushobozi bwinshi ishingiye ku isoko y’imashini ya soliton, itsinda ry’imashini zikoresha frequency comb rifite itandukaniro rikomeye ry’ingufu rihura n’ikibazo cya SNR nke, mu gihe isoko ya soliton ifite spectral output ishobora gukemura iki kibazo neza no gufasha kunoza SNR mu gutunganya amakuru y’urumuri icyarimwe, ifite akamaro kanini mu buhanga.

Iki gitabo, cyitwa “Flat soliton microcomb source,” cyasohotse nk'inyandiko y'ibanze muri Opto-Electronic Science nk'igice cy'ikinyamakuru “Digital and Intelligent Optics”.
