Abstract :
A new digital architecture combining a spatial light modulator written dynamic hologram and a fixed diffractive grating has been demonstrated to produce a tunable wavelength filter with a tuning resolution of 2.5 nm over a 160 nm range. Three modes of a broadband 1.45 μm laser diode have been isolated using the filter and selectively coupled into singlemode communications fibre
