Paper Abstract

This paper presents progress of collinear beam (CB) AOTFs as wavelength routing switches (WRS) in DWDM networks. Significant improvement in the CBAOTF bandpass response was achieved. The measured performance at 1550nm shows a FWHM of 0.5nm and a sidelobe bandpass below 22dB at a wavelength spacing of 0.8nm from the center wavelength. By using two cascaded dual polarization AOTFs, a 2 X 2 WRS can be constructed that yields an extinction ratio greater than 35dB.
