The behaviour of these parameters for a Modified Total Internal Reflection (MTIR) Photonic Crystal Fibre (PCF) is studied when strain is applied. We chose a range of normalized frequency (Λ/λ) and a range of d/Λ and we analyzed the behaviour for different values of strain. The sensibilities of the studied parameter are obtained in the chosen range. Finally, the region of maximum influence of the strain is observed.}, publisher = {SPIE Society of Photo-Optical Instrumentation Engineers}, publisher = {Proceedings of SPIE, 2007, vol. 6619, 661935}, publisher = {Third European Workshop on Optical Fibre Sensors, Nápoles, 2007}, title = {Optical properties of photonic crystal fibers with the strain}, author = {Lázaro Urrutia, José Miguel and Galíndez Jamioy, Carlos Augusto and Quintela Incera, Antonio and Cobo García, Adolfo and López Higuera, José Miguel}, }
