Multiwavelengthlight sourcepapepa rakatsetseka
Optical chips ndiyo nzira isingadzivisiki yekuenderera mberi neMutemo waMoore, yave kubvumirana kweacademia uye indasitiri, inogona kunyatsogadzirisa kukurumidza uye kushandiswa kwesimba matambudziko anotarisana nemagetsi machipisi, inotarisirwa kukanganisa ramangwana rehungwaru komputa uye yekupedzisira-yepamusoro-kumhanya.optical communication. Mumakore achangopfuura, yakakosha tekinoroji budiriro musilicon-based photonics inotarisa pakuvandudza chip level microcavity soliton optical frequency combs, iyo inogona kugadzira yakaenzana yakaganhurwa frequency mizinga kuburikidza neoptical microcavities. Nekuda kwemabhenefiti ayo ekubatanidzwa kwepamusoro, yakafara spectrum uye yakakwirira kudzokorora frequency, chip level microcavity soliton light source ine inogona kushandiswa muhukuru hwekutaurirana, spectroscopy,microwave photonics, kunyatsoyera kuyerwa uye mamwe minda. Kazhinji, kutendeuka kwekushanda kwe microcavity single soliton optical frequency comb inowanzoganhurwa neakakodzera parameter ye optical microcavity. Pasi pesimba repombi chaiyo, simba rekubuda reiyo microcavity imwe soliton optical frequency comb rinowanzo ganhurwa. Iko kuunzwa kwekunze optical amplification system inozokanganisa chiyero chechiratidzo-kune-ruzha. Naizvozvo, iyo flat spectral mbiri ye microcavity soliton optical frequency comb yave kutsvaga kweiyi ndima.
Munguva pfupi yapfuura, boka rekutsvagisa muSingapore rakaita kufambira mberi kwakakosha mumunda weakawanda-wavelength magetsi pamashizha akatsetseka. Chikwata chekutsvagisa chakagadzira optical microcavity chip ine flat, yakafara spectrum uye pedyo ne zero dispersion, uye zvakanyatsorongedza chip chemaziso chine mupendero coupling (kubatanidzwa kurasikirwa kusingasviki 1 dB). Kubva pane optical microcavity chip, iyo yakasimba thermo-optical effect mu optical microcavity inokundwa nehunyanzvi chirongwa chekupomba kaviri, uye iyo yakawanda-wavelength light source ine flat spectral kubuda inoitika. Kuburikidza nemhinduro yekudzora sisitimu, iyo yakawanda-wavelength soliton sosi system inogona kushanda zvakatsiga kweanopfuura maawa masere.
Iyo spectral kubuda kweiyo mwenje sosi ingangoita trapezoidal, iyo yekudzokorora mwero ingangoita 190 GHz, iyo flat spectrum inovhara 1470-1670 nm, iyo flatness inenge 2.2 dBm (yakajairwa kutsauka), uye iyo flat spectral renji inotora makumi manomwe muzana ezvese. spectral range, inovhara S+C+L+U bhendi. Mhedzisiro yekutsvagisa inogona kushandiswa mune yakakwira-capacity optical interconnection uye yakakwirira-dimensionalopticalcomputing systems. Semuyenzaniso, mune yakakura-inogonesa yekuratidzira yekuratidzira system yakavakirwa pa microcavity soliton comb sosi, iyo frequency comb boka rine yakakura simba musiyano rinotarisana nedambudziko reyakaderera SNR, nepo soliton sosi ine flat spectral kubuda inogona kubudirira kukunda dambudziko iri uye kubatsira kuvandudza SNR mune parallel optical information processing, iyo ine kukosha kweinjiniya kukosha.
Iro basa, rakanzi "Flat soliton microcomb sosi," rakaburitswa sebepa rekuvhara muOpto-Electronic Sainzi sechikamu che "Digital uye Intelligent Optics" nyaya.
