ʻO ka modulator māmā Spatial (SLM) he mea pono o ka optical optical device hiki ke hoʻokaʻawale spatially modulation o ka amplitude, phase a polarization state of light waves. Hoʻohana kā mākou mau huahana SLM i hoʻomohala ponoʻī i ka ʻenehana wai aniani e hoʻokele ai i ka hoʻonohonoho ʻana o nā molekole aniani wai ma o nā hōʻailona uila e hoʻokō i ka hoʻoponopono pololei o nā nalu māmā. ʻO kēia mana mana kūpono e hana i ka Spatial Light Modulator (SLM) he "canvas naʻauao" i loko o nā ʻōnaehana optical. Hiki iā ia ke hana i nā ʻano like ʻole o nā māhele māmā paʻakikī i loko o ke ala optical.

Spatial light modulator (SLM) he mea hoʻohiwahiwa i hiki ke hoʻololi i ka manawa maoli o ka amplitude māmā, ka pae, a me ke kūlana polarization ma lalo o ka mana o waho.

ʻO ka hoʻopuehu ʻana i ke kino he ʻano ākea ākea ma ke ʻano, a ʻo ka hoʻopuehu māmā ʻana ma muli o ka paʻakikī a me ka inhomogeneity spatio-temporal o nā ala hoʻolaha māmā i ka media, e laʻa.

I loko o ka ʻōnaehana kamaʻilio fiber optical me nā hōʻailona kino e hoʻomalu a hoʻololi i ka amplitude, frequency, phase, polarization a me nā ʻano ʻē aʻe o nā ʻāpana o ka mea lawe optical o ke kaʻina i kapa ʻia ʻo optical modulation. ʻO ke kuleana o ka modulation optical ka ʻae ʻana i ka ʻike e hoʻohana i nā hiʻohiʻona o ka nalu māmā e hoʻokō i ka wikiwiki wikiwiki a me ka hoʻoili ʻana, a hiki ke pale pono i ka hoʻopili ʻana o nā kahua electromagnetic waho, i ʻoi aku ka paʻa o ka hoʻolaha ʻana o ka ʻike. Me ka hoʻohana nui ʻana o ka ʻenehana hoʻokaʻawale hawewe lōʻihi (DWDM) a me ka ulu nui ʻana o ka hiki ke hoʻoili ʻia o ka fiber optic, ua lōʻihi ka nui o ka ʻenehana SDH, e pili ana i ka wavelength selective switch (WSS) ma ke ʻano he kolu o ka hanauna o ka multi-functional reconfigurable optical insertion and multiplexing (ROADM) ma ke ʻano he kī nui e ʻike ai i ka hanauna hou o ka ʻenehana noiʻi koʻikoʻi. i, a ua ulu wikiwiki.

Me ka hoʻomohala ʻana o ka ʻoihana kamaʻilio kelepona paʻa, ua lilo ka 6th generation mobile communication technology (6G) i wahi wela noiʻi. He kiʻekiʻe ka nui o ka hoʻouna ʻana o 6G, ka nui o ke kahawai nui, ka liʻiliʻi o ka hoʻouna ʻana, ke kiʻekiʻe spectrum maikaʻi a me ka hilinaʻi ikaika, etc. ʻO ka mea nui loa, ʻike ʻo 6G i ka pilina naʻauao nui ma waena o nā kānaka a me nā mea, ʻo ia hoʻi, "Ua pili hohonu nā mea āpau! ". I mea e ʻike ai i nā hiʻohiʻona maikaʻi loa o ka pūnaewele kamaʻilio 6G, pehea e ʻike ai i ka hanauna multi-beam me ka ultra-large-scale antenna array i lilo i wahi wela noiʻi o kēia manawa.

ʻIke ʻia nā hanana Vortex i ke ola, e like me ka ʻauʻau wai ʻauʻau i ka wā e hoʻokahe ai i ka wai, hoʻāla i nā vortex e kaʻawale mai nā moku i ko lākou huakaʻi, nā makani ʻino, nā ʻino, a me ka holo moana. Ua ʻike mua ʻia ke kukui Vortex (e lawe ana i ka momentum angular orbital, OAM) a ua hoʻohana nui ʻia ma ke kahua o ka optics, ʻo ia hoʻi, ka hana ʻana o nā kiʻi vortex a me nā kukuna vortex, a ʻo ka manaʻo o nā kukuna vortex i hāpai mua ʻia e Coullet et al. i ka makahiki 1989. I ka makahiki 1922, L. Allen et al. ua hōʻoia ʻia i ke ʻano o ka OAM i nā vortex beams, ka mea i hoʻokuʻu i ke kula i mua o ka honua.
