Rof Electro-optic modulator EDFA Optical Amplifier Erbium Doped Fiber Amplifier YDFA Amplifier

ʻO ka amplifier optical kahi mea e loaʻa ai kekahi kukui hōʻailona hoʻokomo a hoʻopuka i kahi hōʻailona puka me ka mana optical kiʻekiʻe. ʻO ka maʻamau, ʻo nā mea hoʻokomo a me nā mea hoʻopuka he mau kukuna laser (ʻaʻole kakaikahi nā ʻano kukui ʻē aʻe), e hoʻolaha ana e like me nā kukuna Gaussian ma kahi ākea a i ʻole ma kahi fiber. Loaʻa ka hoʻonui ʻia i loko o kahi mea i kapa ʻia ʻo gain medium, pono e "pump" (ʻo ia hoʻi, hāʻawi ʻia me ka ikehu) mai kahi kumu waho. ʻO ka hapa nui o nā mea hoʻonui i hoʻopaʻa ʻia ma ka optically a i ʻole ka uila uila.
ʻOkoʻa loa nā ʻano mea hoʻonui like ʻole e laʻa i ke ʻano o nā waiwai saturation. No ka laʻana, hiki ke mālama i ka nui o ka ikehu, ʻoiai nā mea hoʻonui hoʻohālikelike optical e hāʻawi i ka hoʻonui wale ʻana i ka wā e loaʻa ana ka pahu paila. E like me kekahi laʻana, ʻoi aku ka liʻiliʻi o ka ikehu semiconductor optical amplifier ma mua o ka fiber amplifiers, a he mea koʻikoʻi kēia no nā kamaʻilio fiber optical.
