摘要: An apparatus for creating an optical noise of a predetermined bandwidth uses amplifier (2,20,50) which amplifies components and produces unpolarized by spontaneous emission, mirror (32,52,98) to reflect the back filter (4,32,34,56,80) that filters out outside bandwidth. The (4,32,-34,56,80) is located so passed are amplified in during additional amplification. Optionally, pollarizer Faraday rotator (30,54,96) used apparatus. created polarized polarizer (34,36,58,60,84,100) after 2 amplifications, rotated then two more times before leaving
