Abstract :
A polarisation-independent, electronically tunable, acousto-optic filter made with commercially available components is demonstrated. It has a bandwidth (FWHM) of 4 nm, two complementary outputs, a fibre-to-fibre insertion loss of 6-8 dB, and is continuously tunable over 1.30-1.56 mu m. It is suitable for use in multiaccess WDM networks requiring approximately=microsecond-tuning time.
