  • In Chapter 8 we introduced transmission-line laser modelling (TMLM). In this chapter, TLLM will be modified to allow the study of dynamic behaviour of distributed feedback laser diodes, in particular the effects of multiple phase shifts on the overall DFB LD performance. We can easily model any arbitrary phase-shift value by inserting some phaseshifter stubs into the scattering matrices of TLLM. This helps to make the electric field distribution and hence light intensity of DFB LDs more uniform along the laser cavity and hence minimise the hole burning effect. ...

  • In this paper, we overview some configurations of photonic devices for measuring mechanical strain and wavelength shift without use of spectrometer, which have been developed recently and demonstrated large potential application in sensing technique with low cost.
