AB  - In this paper, a theoretical analysis of recently developed tapered chirped fiber 
      Bragg gratings (TCFBG) written in co-directional and counter-directional 
      configurations is presented. In particular, the effects of the synthesis of 
      chirps resulting from both a fused taper profile and a linearly chirped fringe 
      pattern of the induced refractive index changes within the fiber core are 
      extensively examined. For this purpose, a numerical model based on the transfer 
      matrix method (TMM) and the coupled mode theory (CMT) was developed for such a 
      grating. The impact of TCFBG parameters, such as grating length and steepness of 
      the taper transition, as well as the effect of the fringe pattern chirp rate on 
      the spectral properties of the resulting gratings, are presented. Results show 
      that, by using the appropriate design process, TCFBGs with reduced or enhanced 
      resulting chirp, and thus with widely tailored spectral responses, can be easily 
      achieved. In turn, it reveals a great potential application of such structures. 
      The presented numerical approach provides an excellent tool for TCFBG design.
