ʻO nā ʻenehana optical multiplexing a me kā lāua male ʻana no ke kamaʻilio ma-chip a me ka fiber optical

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 "Optical multiplexing techniques and their marriage" maOpto-ElectronicNā holomua no ka on-chip akamaʻilio fiber optical: he loiloi. Ua hoʻomohala ka pūʻulu noiʻi a Polofesa Khonina i kekahi mau mea ʻokoʻa ʻokoʻa no ka hoʻokō ʻana i ka MDM ma kahi ākea afiber optics. Akā ʻo ka bandwidth pūnaewele e like me "nā ʻaʻahu ponoʻī", ʻaʻole nui loa, ʻaʻole lawa. Ua hoʻokumu nā kahe ʻikepili i kahi koi pahū no ke kaʻa. Ke pani ʻia nei nā leka uila pōkole e nā kiʻi animated e lawe i ka bandwidth. No nā ʻikepili, wikiō a me nā leo hoʻolaha leo i nā makahiki i hala aku nei i nui ka bandwidth, ke ʻimi nei nā luna kelepona i kēia manawa e hana i kahi ala kūpono ʻole e hālāwai ai i ka koi pau ʻole no ka bandwidth. Ma muli o kona ʻike nui ma kēia ʻāpana noiʻi, ua hōʻuluʻulu ʻo Polofesa Khonina i nā holomua hou loa a koʻikoʻi loa ma ke kahua o ka multiplexing e like me kāna hiki. ʻO nā kumuhana i uhi ʻia i ka loiloi ʻo WDM, PDM, SDM, MDM, OAMM, a me nā ʻenehana hybrid ʻekolu o WDM-PDM, WDM-MDM, a me PDM-MDM. Ma waena o lākou, ma ka hoʻohana wale ʻana i kahi multixer WDM-MDM hybrid, hiki ke ʻike ʻia nā kaha N × M ma o nā hawewe N a me nā ʻano alakaʻi M.

ʻO ka Institute of Image Processing Systems o ka Russian Academy of Sciences (IPSI RAS, i kēia manawa he lālā o ka Federal Scientific Research Center o ka Russian Academy of Sciences "Crystallography and Photonics") i hoʻokumu ʻia ma 1988 ma ke kumu o kahi hui noiʻi ma Samara. Kulanui Mokuʻāina. 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 helu a me nā noiʻi 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) me ka hui pū ʻana me ka hui o ka Nobel Laureate i ka physics, Academician Alexander Mikhailovich Prokhorov. I nā makahiki i hala iho nei, ua noi aku nā kānaka ʻepekema IPSI RAS i nā ʻano mea DOE he nui ma nā kamepiula, a laila hana ʻia ia mau mea ma ke ʻano o nā holograms superimposed phase me nā ʻano laser transverse mau. ʻO nā laʻana e pili ana i nā vortices optical, mode Lacroerre-Gauss, mode Hermi-Gauss, mode Bessel, hana Zernick (no ka nānā ʻana aberration), etc. Loaʻa nā hopena ana ma ke ʻano o ka correlation peaks ma kekahi mau wahi (diffraction orders) ma ka mokulele Fourier o kaʻōnaehana ʻōpika. Ma hope mai, ua hoʻohana ʻia ke kumumanaʻo no ka hoʻoulu ʻana i nā kaola paʻakikī, a me ka demultiplexing beams i nā fiber optical, free space, a me ka media turbulent me ka hoʻohana ʻana i DOE a me spatial.ʻO nā mea hoʻololi hoʻololi.
