In Brillouin-assisted slow-light the induced delay is always linked to a particular gain; i.e., the delay is directly proportional to the gain expressed in decibels. However, for certain applications this may be restrictive, and techniques to decouple gain and delay are thus of considerable practical interest. We propose a way to effectively decouple these two parameters that, subject to inherent physical constraints, can be used to obtain a delay line capable of providing arbitrary gain (or alternatively an amplifier that can provide arbitrary delay for a fixed gain). The decoupling mechanism relies upon operating the amplifier in the pump-depletion regime. Other advantages of this approach, as well as its limitations in the context of slow-light, are discussed.
