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

Chipangizo chowunikira ndi chipangizo chomwe chimalandira kuwala kwa siginecha ndikutulutsa chizindikiro chokhala ndi mphamvu yayikulu kwambiri. Nthawi zambiri, zolowera ndi zotuluka ndi matabwa a laser (kawirikawiri mitundu ina ya nyali zowala), mwina zimafalikira ngati matabwa a Gaussian pamalo aulere kapena mu ulusi. Kukulitsa kumapezeka muzomwe zimatchedwa kuti gain medium, zomwe ziyenera "kuponyedwa" (ie, kuperekedwa ndi mphamvu) kuchokera kunja. Ma amplifiers ambiri amapangidwa ndi magetsi kapena optical.
Mitundu yosiyanasiyana ya amplifiers imasiyana kwambiri mwachitsanzo potengera kuchuluka kwazinthu. Mwachitsanzo, ma media amtundu wa laser osowa padziko lapansi amatha kusunga mphamvu zochulukirapo, pomwe ma amplifiers owoneka bwino amapereka kukulitsa pokhapokha mtengo wapampu ulipo. Monga chitsanzo china, ma semiconductor optical amplifiers amasunga mphamvu zochepa kwambiri kuposa zokulitsa ulusi, ndipo izi zimakhala ndi tanthauzo lofunikira pakulumikizana kwa ulusi wa kuwala.
