Ma muli o nā'āpanaʻehā maʻamau

Ua hōʻikeʻia kēia pepa iʻehā mau'āpana modula (e hoʻololi ana i ka palenaʻo Laser i loko o ka Nanosecould a me Subnanoosecond. Hoʻopili kēia iā Aom (ACOUTO-OCOUCTO-OPTIC MODIL), EOM (Electro-Optic Modetion), Som /Soia(Semiconductor Light Amplification e hōʻikeʻia anaʻo Semiconductor Modulation), aKūmole Laser Modula. ^. I waena o lākou, aom,Eom, I ka lā ma waho o ke kikowaena o waho, a iʻole nā ​​modulation modula.

1. Acoutto-optic Model

ʻO ka modula-Ocousto-optic he kaʻina pilikino e hoʻohana ana i ka hopena Acousto-optic e hoʻouka i kaʻike i ka mea lawe optical lawe. Ke mili i ka wā e kohoʻia, ke kau inoa uila (Amplipel Modetion) i hoʻohana muaʻia ma ka Transduces Electroitic, kahi e hoʻohuli ai i ka hōʻailona Electrical i ka Pūnaewele Ultrasoid. Ke hele nei ka nalu māmā ma loko o ka acousto-optic medum, ke hoʻololiʻia ka mea lawe optical i ka loaʻaʻana o kaʻike

2. Electro-optical modulator(Eom)

ʻO kahi modrol a me ka modrop ʻO ka hopena maloʻa uilaʻo ia ka mea i hoʻohanaʻia ka voltage i ka crysat eponstal, a me ka molarizaino o ka uila o ke kukui uila.

Kiʻi:ʻO ka hoʻonohonoho maʻamau o ke kaʻa kaʻa eom

Hoʻohana pinepineʻiaʻo SemiconnduordʻO Erbium-Doped Fiber Amphifier). ʻO kahi modulator Opelika Semical (Som)ʻo ia ka mea like me ka seamopont i ka mea i hoʻohanaʻia me ka mea i hoʻohanaʻia ma keʻano he mea hoʻohanaʻia I ka manawa i hoʻohanaʻia ai no ka hōʻailona hōʻailona optical, e hāʻawiʻia kahi kaʻa kaʻa i kēia manawa i ka sora e hana e hana ai ka shea ma ka'āina linear; I ka wā e hoʻohanaʻia ai e hoʻololi i nā pulu optical Ke hoʻohana nei i kaʻikeʻana i ka soa a me nā hiʻohiʻona a me nā hiʻohiʻona o kēiaʻano model Ka nui loa no kekahi mau hiʻohiʻona e koi pono i ka nui o ka nui, ka mana o ka mana a me ka hoʻonuiʻana i ka mana.

4. Hiki i ka modula pololei ke hoʻololi i ka hōʻailona o ka mea e pili ana i ka hanaʻana o ka laser, e like me keʻano he 3 Nanosecond pull Hiki keʻikeʻia aia kahi Spike i ka hoʻomakaʻana o ka Puki, i laweʻia e ka hoʻomaha o ka mea lawe kaʻa. Inā makemakeʻoe e kiʻi i kahi pulse o nā 100 picoseconds, hiki iāʻoe ke hoʻohana i kēia spike. Akā,ʻaʻole mākou makemake e loaʻa kēia spike.

He kūponoʻo Aom no kaʻike mana optical i kahi manawa kupanaha a loaʻa i kahi hana loli lōʻihi. Ua wikiwikiʻo Eom, akā he kiʻekiʻe ka paʻakikī o ka hoʻokele a me ka paʻakikī o ka hopena. ʻO Som (SOA)ʻo ia ka hopena maikaʻi loa no GHZ Speed ​​a me ke kiʻekiʻe o ka hoʻonuiʻana, me ka liʻiliʻi haʻahaʻa a me nā hiʻohiʻona haʻahaʻa a me nā hiʻohiʻona liʻiliʻi. ʻO nā doides Laser Dioder ka mea maʻalahi loa, akā e makaʻala i nā loli i nā hiʻohiʻona maʻalahi. Loaʻa i kēlā me kēia kumuhana modula i loaʻa i kona mau pono pono'ī a me nā hemahema, a he mea nui ka hoʻomaopopo pono i kēlā me kēia kumuhana, a koho i nā hana kūpono. No ka laʻana, ma kaʻikeʻoleʻana i ka nānāʻana,ʻo ka manaʻo kuʻuna ka nui, akā i kekahi mau papa hana hana hou, a hoʻomaikaʻi i ka nui o nā papa hana hou, a hoʻomaikaʻi i ka nui o nā papa hana I ka'ōnaehana kamaʻilio,ʻo ka'ōnaehana haʻahaʻa haʻahaʻa haʻahaʻa e hoʻopili pinepine ai i ka papahana modectina pololei, a hoʻohana ka'ōnaehana kiʻekiʻe kiʻekiʻe i ka hoʻolālā o ka electro-optic
