Abstract
The invention relates to multiport routing devices for routing optical signals which also provide beam attenuation by imparting a controllable offset between an optical beam and a selected optical port. A multiport optical routing device of the present invention has a plurality of non-equally spaced optical ports disposed in a row to enable beam offset for attenuation without substantially increasing optical crosstalk between adjacent ports in a compact port arrangement.
