Kubudirira kwechipiri Halkonics mune yakawandisa spectrum

Kubvira pakuwanikwa kwechipiri-kurongeka nonlinear mhedzisiro muma1960s, yakamutswa kufarira, zvakavakirwa pachiitiko chechipiri, uye kugadzirwa kubva kune yakanyanya kuwanda kusvika kune yakanyanya infrared band yelasers, kusimudzira zvakanyanya kukura kweLaser,OpticalKugadziriswa kweruzivo, yakakwirira-resolution microscopic kufungidzira uye mamwe minda. Zvinoenderana neisipolenarOpticsuye polarization dzidziso, iyo-yakarongeka nonlinear optical mhedzisiro inoenderana neCymmetal Symmetry, uye iyo isiri yepletaling haina zero chete mune isiri-yepakati inversion symmetric media. Sezvinonyanya kukoshesa chechipiri-kurongeka nonlinear mhedzisiro, yechipiri Hurmonics inokanganisa chizvarwa chavo uye kushandiswa kunobudirira muQuartz fiber nekuda kweiyo Amorphous Fomu uye Symmetry yeCenter Inversion. Parizvino, nzira dzekupora (Optical polarization, polarization polarization, emagetsi polarization) inogona kubatsira symmetry yezvinhu zvekunze fiber fiber fiber fiber fiber fiber fiber fiber fiber fiber fiber fiber fiber fiber fiber fiber Fiber Nekudaro, nzira iyi inoda tekinoroji yakaoma uye inoda kugadzirira tekinoroji, uye inogona kungosangana neiyo Quasi-chikamu chinofananidza mamiriro pane discrete wavelengths. Iyo Optical Fiber Resonant mhete yakavakirwa pamhepo yemadziro maitiro anogumira iyo yakafara spectrumu yakaenzana neyechipiri Halkonics. Nekutyora symmetry yeiyo fiber yeiyo fiber, yechipiri yekisimusi mune yakasarudzika chimiro inosimbiswa kune imwe nhanho, asi ichiri kutsamira pombi yechibatopo neyekumusoro kwazvo. Naizvozvo, chizvarwa chechipiri-kuronga nonlinear mhedzisiro mune zvese-fiber zvimiro zvekupindirana, ndizvo zvinetso zvekupenya, uye zvine kukosha kwesainzi, uye kukosha kwakakosha kwesainzi uye kukosha kwakawanda.

Chikwata chekutsvagisa muChina chakakurudzira iyo yakarongedzwa Gallium Solenide Crystal chikamu chekubatanidza chirongwa chine micro-nano fiber. Nekutora mukana weiyo yepamusoro yechipiri-yakarongeka-yekuraira yeGalenside yeClension Crystals, kuwanda-kuwanda kwekushandurwa kwemugwagwa muFiber uye kugadzirira kweBroadband wechipiriZvigadzirwa zvechiedza. Iyo inoshanda zvakanaka yechipiri Hurtonic uye sum nguva yehurongwa zvakanyanya muhurongwa hunonyanya kuenderana nemamiriro ezvinhu matatu matatu ekutevera: Iyo Yakareba Chiedza - Chakareba Kubatana Pakati peGalenside uyeMicro-Nano Fiber, iyo yakakwirira yechipiri-yakarongeka-yekare-kurongeka kweiyo yakarongeka yeGalensium Slenside Crystal, uye chikamu cheChikamu cheChikamu cheKudzvinyirira uye kuwanda kwekupedzisira.

Mukuedzwa, iyo micro-nano fiber yakagadzirirwa nemurazvo wekutarisa system ine yunifomu yenzvimbo muhurongwa hweMillimeter, iyo inopa yakareba isina kujairika chidimbu chechiedza chepombi uye yechipiri Harmonic wave. Iyo yechipiri-kurongeka isiri yeplazarability yeiyo yakabatanidzwa Gallen Scenside Crystal inodarika 170 pm / v, iyo yakanyanya kukwirisa kupfuura iyo Intrinsic Polarizability yeiyo Optical Fiber. Zvakare, iyo yakareba-yakarayirwa gadziriro yeGalenide Crystal yekukanganisa kwechipiri yekukanganisa kwechipiri Zvinotonyanya kukosha, chikamu chinoenderana nepamhepo yepamhepo yekupomba

Mamiriro ezvinhu ari pamusoro apa akavhara hwaro hwekushanda uye rakakura-band-band kufarirwa kwechipiri Halkonics mune micro-nano fiber. Kuedza kunoratidza kuti kubudiswa kwechipiri Harmonics kuNanowt Kupfuurirazve. Nekutsiva mwenje wepombi ne ultra-radiant mwenje-inobvisa diode (sled) yebhandi regumi nemabhandi neBandwidth neBandwidth ye 28.3 nm inogadzirwa (Mufananidzo 2). Uye zvakare, kana makemikari apor position inogona kushandiswa kutsiva tekinoroji yekufambisa yekufambisa muchidzidzo ichi, uye vashoma veGalensi
