Abstract
Operation and design considerations are described for a general class of symmetric directional coupler switches. Performance limitations are discussed in terms of asymmetries. Comparisons are made between various waveguide and electrode geometries, Measured devices operating at λ = 0.83 μm have a Vπ voltage ⋅ length product under 30 V ⋅ mm and an extinction ratio greater than 28 dB in each output state.
