Machipisi eOptical inzira isingadzivisiki yekuenderera mberi neMoore's Law, yave kubvumirana kwevakadzidza nemaindasitiri, inogona kugadzirisa zvinobudirira matambudziko ekumhanya nekushandiswa kwesimba anotarisana nemachipisi emagetsi, inotarisirwa kukanganisa ramangwana remakombiyuta akangwara uye kumhanya kwakanyanya.kutaurirana kwemazisoMumakore achangopfuura, kufambira mberi kwakakosha kwetekinoroji mu silicon-based photonics kunotarisa pakugadzirwa kwema chip level microcavity soliton optical frequency combs, ayo anogona kugadzira ma frequency combs akapatsanurwa zvakaenzana kuburikidza nema optical microcavities. Nekuda kwezvakanaka zvayo zvekubatanidzwa kwepamusoro, wide spectrum uye high repetition frequency, chip level microcavity soliton light source inogona kushandiswa mukukurukurirana kwakawanda, spectroscopy,mifananidzo ye microwave, kuyera kwakarurama nedzimwe nzvimbo. Kazhinji, kushanda zvakanaka kwe microcavity single soliton optical frequency comb kunowanzo ganhwa nematanho akakodzera e optical microcavity. Pasi pesimba repombi chaiyo, simba rekubuda kwe microcavity single soliton optical frequency comb rinowanzo ganhwa. Kuunzwa kwe external optical amplification system kuchakanganisa chiyero chesignal-to-noise. Nokudaro, flat spectral profile ye microcavity soliton optical frequency comb yave iri kutsvagwa kwemunda uyu.

Munguva pfupi yapfuura, chikwata chekutsvagisa muSingapore chafambira mberi zvikuru munyaya dzezviwanikwa zvemwenje zvine mawavelength akawanda pamapepa akatsetseka. Chikwata chekutsvagisa chakagadzira chip ye optical microcavity ine flat, broad spectrum uye nearly zero dispersion, uye chakarongedza chip ye optical zvinobudirira ne edge coupling (coupling loss iri pasi pe 1 dB). Zvichibva pa chip ye optical microcavity, simba guru re thermo-optical mu optical microcavity rinokundwa ne technical scheme yekupomba kaviri, uye multi-wavelength light source ine flat spectral output inowanikwa. Kuburikidza ne feedback control system, multi-wavelength soliton source system inogona kushanda zvakadzikama kweanopfuura maawa masere.

Kubuda kwespectral kubva kuchiedza kunenge trapezoidal, repetition rate inenge 190 GHz, flat spectrum inofukidza 1470-1670 nm, flatness inenge 2.2 dBm (standard deviation), uye flat spectral range inotora 70% yespectral range yese, ichifukidza S+C+L+U band. Mhedzisiro yekutsvagisa inogona kushandiswa mu high-capacity optical interconnection uye high-dimensional.chiedzamasisitimu emakombiyuta. Semuenzaniso, muhurongwa hwekuratidzira kutaurirana hune simba guru hwakavakirwa pasosi ye microcavity soliton comb, boka re frequency comb rine musiyano mukuru wesimba rinotarisana nedambudziko reSNR yakaderera, nepo soliton source ine flat spectral output inogona kukunda dambudziko iri zvinobudirira uye kubatsira kuvandudza SNR mukugadzirisa ruzivo rwe optical parallel, iyo ine kukosha kwakakosha kweinjiniya.

Basa iri, rine musoro unoti “Flat soliton microcomb source,” rakabudiswa sepepa rekufukidza muOpto-Electronic Science sechikamu chemagazini ye“Digital and Intelligent Optics”.
