摘要: Controllable fiber optic attenuators and attenuation systems ( 100 ) are disclosed for controllably extracting optical energy from a 30 ), therefore attenuating the signal being transmitted through ). In one aspect, material is removed portion of thereby exposing surface which can be extracted. A controllable formed over according to changeable stimulus applied thereto, affects refractive index thereof. an improved embodiment, exposed controlling amount extracted optic, bulk material, into radiated.
