ABSTRACT

The generation of ultrashort pulses with high repetition rates is very important for future ultrahigh bit-rate optical communication systems. An active mode-locked ›ber laser is a potential source of such pulses. However, the pulse repetition rate is usually limited by the bandwidth of the intracavity modulator. Hence, some techniques have to be applied to increase the repetition frequency of the pulses generated. In this chapter, we focus on the generation of high-repetition-frequency optical pulses using the fractional temporal Talbot effect and brie—y on some other repetition rate multiplication techniques. The stability studies using the phase plane analysis (which is commonly employed to study the stability of nonlinear control systems) will also be discussed. The phase plane analysis is commonly used in nonlinear control systems and, to the best of our knowledge, this is the ›rst time that the technique is being applied in the repetition rate multiplication laser system.
