Abstract
An optical switch based on a transversal filter configuration is demonstrated. The switch consists of cascaded 3 dB optical power splitters and a phase shifter array. By using a silica-based planar lightwave circuit, a 1×4 optical switch was realised. A characteristic of the switch is that its power consumption is constant regardless of the output selection.
