Abstract :
We demonstrate system level performance and rapid switching (10 mus) of a 1times3 wavelength multiplexer/demultiplexer (mux/demux) based on a Gires-Tournois interferometer with cyclically tunable center wavelengths. Group delay ripple within the passband is measured to be <8 ps. Less than 0.5-dB power penalty is observed for 10-Gb/s data propagating through the demux. Additionally, rapid optical code-division multiple-access code hopping using this tunable demux has been shown
