A 1 × 5 optical switch with a switching speed of microseconds is demonstrated. Switching between different channels in a planar lightwave circuit waveguide array was controlled using an electro‐optic beam deflector. A single crystal of potassium tantalate niobate (KT a 1− x N b x O 3 , KTN) was used as a deflector to realise this operation. A switching speed of 8.1 μs was demonstrated for the switching of two adjacent channels.
