Abstract :
This communication considers the use of optical networks excited by a light signal modulated at microwave frequencies in order to perform microwave functions. Using some basic single mode optical fibre elements at 1.3 ¿m we have realised an unbalanced Mach-Zehnder interferometer that can be used as a microwave band rejection filter. The experimental results show good performances with a rejection ratio higher than 40 dB and a very good phase linearity.
