Abstract

An integrated optical device including an electrically controllable switching element and an electrically controllable attenuating element cascaded together, wherein the switching element may be switched from a maximum attenuation state at zero electrical power input to a minimum attenuation state by the input of electrical power, and wherein the attenuating element may be switched from a minimum attenuating state at zero electrical power input to a state of greater attenuation by the input of electrical power, the attenuating element capable of exhibiting greater maximum attenuation than the switching element.
