摘要： A photocarrier-injecting variable optical attenuator that operates by injecting photocarriers into a light transmitting waveguide from a second, injection light source. The light transmitting waveguide may be defined by a ridge extending from a slab of a light transmitting medium. The light transmitting waveguide is transparent to signal light. Light emitted from the second, injection light source is optically absorbed by the light transmitting waveguide to introduce photocarriers in a plurality of configurations, thereby attenuating the signal light.
