A new approach to design digitally tunable optical fllter system by using semiconductor optical ampliflers (SOAs) and Dense Wavelength Division Multiplexed (D.W.D.M.) thin fllm fllter based wavelength selection elements is presented. The system designed with this approach is very easy to conflgure and expand, smaller in size, lesser in weight, cheaper in cost and consuming less power as compared to design suggested by other researchers recently.
