ABSTRACT: The cascadability of
uniform fibre Bragg grating for 40 Gbit/s return to zero on-off keying to
non-return to zero on-off keying format conversion has been shown using OptSim
simulation program. The main idea of this approach is use of specially designed
uniform fibre Bragg grating with appropriate transfer function for shaping of
40 Gbit/s return to zero on-off keying optical spectrum. Error free performance
is achieved after four cascades of uniform fibre Bragg grating with different
reflectivity values.
