ʻO nā ʻenehana multiplexing optical a me kā lākou male ʻana no ka kamaʻilio on-chip a me ka optical fiber

Ua paʻi ka hui noiʻi o Prof. Khonina mai ka Institute of Image Processing Systems o ka Russian Academy of Sciences i kahi pepa i kapa ʻia ʻo "Optical multiplexing techniques and their marriage" maʻOpto-UilaNā holomua no ka on-chip a mekamaʻilio fiber optic: he loiloi. Ua hoʻomohala ka hui noiʻi a Polofesa Khonina i kekahi mau mea optical diffractive no ka hoʻokō ʻana i ka MDM ma kahi ākea anā ʻike maka fiberAkā, ua like ka bandwidth pūnaewele me "nā kapa komo pono'ī", ʻaʻole nui loa, ʻaʻole lawa. Ua hoʻokumu ke kahe ʻikepili i kahi koi pahū no ke kaʻa. Ke pani ʻia nei nā leka uila pōkole e nā kiʻi animated e lawe ana i ka bandwidth. No nā pūnaewele hoʻolaha ʻikepili, wikiō a me ka leo i loaʻa i kekahi mau makahiki i hala aku nei he nui ka bandwidth, ke nānā nei nā luna kelepona e lawe i kahi ala maʻamau ʻole e hoʻokō ai i ke koi pau ʻole no ka bandwidth. Ma muli o kona ʻike nui ma kēia wahi noiʻi, ua hōʻuluʻulu ʻo Polofesa Khonina i nā holomua hou loa a koʻikoʻi loa ma ke kahua o ka multiplexing e like me ka hiki iā ia. ʻO nā kumuhana i uhi ʻia ma ka loiloi ʻo WDM, PDM, SDM, MDM, OAMM, a me nā ʻenehana hybrid ʻekolu o WDM-PDM, WDM-MDM, a me PDM-MDM. I waena o lākou, ma ka hoʻohana ʻana i kahi multiplexer hybrid WDM-MDM, hiki ke hoʻokō ʻia nā kahawai N × M ma o nā nalu N a me nā ʻano alakaʻi M.

Ua hoʻokumu ʻia ka Institute of Image Processing Systems of the Russian Academy of Sciences (IPSI RAS, i kēia manawa he lālā o ke Federal Scientific Research Center of the Russian Academy of Sciences "Crystallography and Photonics") i ka makahiki 1988 ma ke kumu o kahi hui noiʻi ma ke Kulanui ʻo Samara State. Ke alakaʻi ʻia nei ka hui e Victor Alexandrovich Soifer, he lālā o ka Russian Academy of Sciences. ʻO kekahi o nā kuhikuhi noiʻi o ka hui noiʻi ʻo ia ka hoʻomohala ʻana i nā ʻano helu a me nā haʻawina hoʻokolohua o nā kukuna laser multi-channel. Ua hoʻomaka kēia mau haʻawina i ka makahiki 1982, i ka wā i hoʻokō ʻia ai ka multi-channel diffracted optical element (DOE) mua ma ka laulima ʻana me ka hui o ka Nobel Laureate ma ke physics, ʻo Academician Alexander Mikhailovich Prokhorov. I nā makahiki ma hope mai, ua hāpai, hoʻohālike a aʻo nā kānaka ʻepekema IPSI RAS i nā ʻano he nui o nā mea DOE ma nā kamepiula, a laila hana iā lākou ma ke ʻano o nā holograms pae like ʻole me nā ʻano laser transverse kūlike. ʻO nā laʻana e komo pū me nā vortices optical, ke ʻano Lacroerre-Gauss, ke ʻano Hermi-Gauss, ke ʻano Bessel, ka hana Zernick (no ka nānā ʻana i ka aberration), a pēlā aku. Hoʻopili ʻia kēia DOE, i hana ʻia me ka hoʻohana ʻana i ka lithography electron, i ka nānā ʻana i ka beam ma muli o ka decomposition mode optical. Loaʻa nā hopena ana ma ke ʻano o nā piko correlation ma kekahi mau kiko (nā kauoha diffraction) ma ka mokulele Fourier o kaʻōnaehana ʻike makaMa hope mai, ua hoʻohana ʻia ke kumumanaʻo e hana i nā kukuna paʻakikī, a me nā kukuna demultiplexing i nā fiber optical, ka hakahaka manuahi, a me nā media turbulent me ka hoʻohana ʻana iā DOE a me ka spatialNā modulators optical.
