The 1.5- mu m optical filter exhibits a tuning range as wide as 188 GHz (15 AA), with 23-dB constant gain and 5-GHz constant bandwidth. A 25-channel wavelength selection with less than -10-dB crosstalk is expected with this filter. The wavelength-tunable optical filter has applications in wavelength-division multiplexing lightwave transmission systems and wavelength division photonic switching systems.<>
