| Abstract: | The effect of profile imperfections, like axial index dip and layered structure in the inner cladding, on the leakage loss of LP01 mode in MCVD made single-mode depressed index cladding (DIC) fibres is investigated quantitatively through a matrix approach. The study reveals that these apparent profile imperfections may greatly affect leakage loss coefficients especially at longer wavelengths. A typical example of the presence of a linear axial dip along with ripples in the inner cladding is seen to increase the leakage loss coefficient of the LP01 mode to 43.44 dB/km from a value of 0.25 dB/km at 1.3 μm in the absence of profile perturbation |
