Abstract: | In this paper we report a numerical investigation of an all-fibre narrowband transmission filter in the arrangement of two
identical photo-imprinted Bragg gratings symmetrically located in each arm of a Michelson Interferometer, simulating, thus,
an add-drop filter. The transmission characteristics and in addition the crosstalk level and extinction ratio, were studied.
The coupled mode theory and the fourth-order Runge-Kutta method were applied, respectively, to solve the coupled differential
equations. This is the first study, as far as we now, of the performance of this device considering the nonlinearity of the
fibre coupler and linearity of the fibre Bragg gratings. The device is presenting a highly nonlinear behavior dependence in
dephasing and pump power. |
