“…This is achieved by simply examining the propagation of these pulses through two key components of any optical network (i.e., optical fiber and an optical filter), as a function of the SMSR. Our results show that, although many of the previous reported wavelength-tunable pulse sources using the SSGS technique had SMSR's which varied between 10-25 dB as the output pulse wavelength was tuned [6], [7], in practice, such pulses may be unsuitable for use in either WDM or OTDM systems. The reason for this lies in the buildup of noise on the optical pulses due to the mode partition effect [8], [9].…”

Abstract-The side-mode suppression ratio (SMSR) of selfseeded gain-switched optical pulses is shown to be an extremely important factor for the use of these pulses in optical communications systems. Experiments carried out involving pulse propagation through dispersion-shifted fiber and a bandpass optical filter demonstrate that, for SMSR values of less than 25 dB, the buildup of noise due to the mode partition effect may render these pulses unsuitable for use in optical communications systems.

“…An important drawback of these techniques, however, is the periodic nature of the pulse train, and as a consequence they do not allow the generation of coded messages. Methods that allow more flexibility are self-seeding [19]- [21], weak optical feedback [22]- [25], and optical injection [26]- [28]. Optical injection from a narrowband tunable master source is one of the most promising techniques.…”

Abstract-The performance of a device based on modified injection-locking techniques is studied by means of numerical simulations. The device incorporates master and slave configurations, each one with a DFB laser and an electroabsortion modulator (EAM). This arrangement allows the generation of high peak power, narrow optical pulses according to a periodic or pseudorandom bit stream provided by a current signal generator. The device is able to considerably increase the modulation bandwidth of free-running gain-switched semiconductor lasers using multiplexing in the time domain. Opportunities for integration in small packages or single chips are discussed.

“…Gain switching of a semiconductor laser diode is probably one of the most reliable methods to generate optical pulses, and by employing self seeding [7] of a gain-switched Fabry-Pérot (FP) laser, it is possible to obtain high-quality wavelength tunable single-mode pulses which have low timing jitter and good spectral purity. Nonetheless, a major disadvantage with the self-seeded gain-switched (SSGS) scheme is that the length of the external cavity has to be continuously tuned so that the pulse repetition frequency is an integer multiple of the cavity round-trip frequency.…”
