Maximization of Gain in Slow-Light Silicon Raman Amplifiers

Figure 1

(a) Ultimate signal gain (dashed curves) and optimal amplifier length (solid curves) plotted as functions of 𝜏_𝑐 for an SRA operating in the undepleted-pump regime when 𝑆_𝑠=𝑆_𝑝=1; different colors correspond to different values of 𝛼_𝑠=𝛼_𝑝≡𝛼. (b) Input and output pump intensities calculated as a function of 𝜏_𝑐 using (10) with 𝑆_𝑝=1. Refer to text for other parameters.
