Optical Vakawanda maitiro uye imba yavo ye on-chip: ongororo

Optical dzakawanda nzira uye muchato wavo wear-chip uyeOptical fiber kutaurirana: ongororo

Optical marobhoti maitiro enyaya inokurumidza kutsvagisa, uye nyanzvi pasi rese vari kuitisa kutsvagurudza mumunda uyu. Kwemakore, akawanda akawanda matekinoroji akadai seyakawona Wavelengent Discobling Multiplexing (WDM) tekinoroji inogonesa masaini maviri kana kupfuura emazwi maviri ekuwisirwa kuti aenderane nemuti mumwechete wekurasikirwa kweiyo fiber. Iyo dzidziso yacho yakatanga kuongororwa nekunonoka muna 1970, uye yakanga isiri kusvika 1977 kuti kutsvagisa kwehunyanzvi hweWDM kwakatanga, uko kwakanangana nekushandiswa kwekutaurirana network. Kubva ipapo, nekukura kwekuenderera kweOptical Fiber, Tsime Renje, PhotomdetectorUye mamwe minda, kuongorora kwevanhu kweWDM tekinoroji kwakakurudzira zvakare. Iko mukana wePolarization Kuwedzera (PDM) ndiko kuti huwandu hwekutapurirwa kwemasangano kunogona kuiswa pachinzvimbo chechidimbu chechiedza chimwe chechiedza, uye nzira mbiri dzekunze dzakaparadzirwa uye dzakazvimiririra dzakazviratidza pakugamuchira kunopera.

Sezvo kudikanwa kweiyo yepamusoro data data inoenderera mberi nekukura, iyo yekupedzisira dhizaini yerusununguko rwekushamisika, nzvimbo, yakadzidzwa zvakanyanya pamusoro pemakore gumi apfuura. Pakati pavo, iyo nzira inodavirira akawanda (MDM) inonyanya kugadzirwa ne n transmitters, iyo inozoonekwa ne spatial modelplexer. Pakupedzisira, chiratidzo chinotsigirwa nemhando yemweya inotumirwa kune yakaderera-mode fiber. Munguva yekuparadzira chiratidzo, zvese modes pane imwe chete wavelength inobatwa seyunivhesiti yekutsikirira (sdm) supplified, yakarongedzwa uye yakawedzerwa panguva imwe chete, pasina kukwanisa kuwana zvakasiyana maitiro maitiro. MuMDM, akasiyana spatial contours (kureva kuti, maumbirwo akasiyana) ematanho anopihwa kune akasiyana chiteshi. Semuenzaniso, chiteshi chinotumirwa pamusoro peiyo laser beam iyo yakaumbwa sekona, mraba, kana denderedzwa. Zvimiro zvinoshandiswa neMDM mune chaiyo-nyika zvikumbiro zvakaoma uye zvine akasiyana masvomhu uye emuviri maitiro. Iyi tekinoroji ndeyekupokana zvakanyanya nekuvandudzwa kwekuratidzira mune fiber optic data kutapurirana kubvira kuma1980. Tekinoroji yeMDM inopa chirongwa chitsva kuti zviite mimwe nzira uye kuwedzera chinongedzo kugona uchishandisa imwe chete wavelength kutakura. Orbital Angular Metalum (OAM) hunhu hwemagetsi emafungu emagetsi umo nzira yekunyepedzera inotsanangurwa neiyo helical phase wavefront. Sezvo ichi chimiro chinogona kushandiswa kutanga nzira dzakasiyana, Wireless Orbital Angular Mettlexing (OAMM) rinogona kuwedzera huwandu hwekutapurika mukutandwa kwepamusoro (senge isina waya yekudzokera).
