Rare-earth doped single-mode optical fibres are ideal sources for producing mode locked pulses of very short duration since they have large fluorescence linewidths. To make full use of the linewidth very fast modulators or saturable absorbers are necessary. This work investigates the use of Multiple Quantum Well (MQW) modulators for modelocking and Q-switching fibre lasers. The particular attraction of this approach is that MQW modulators offer good on/off ratios for low voltage drive and are compact in size. Work carried out by Whitehead et al [1] led to the development of the Asymmetric Fabry Perot modulator (AFPM) structure which can achieve very high contrast by using MQW electro-absorption to obtain complete destructive interference of light reflected from the device
