Abstract
The first realisation of a singlemode waveguide modulator based on Wannier-Stark localisation exhibiting a 0.75 V drive voltage and a 2 GHz cutoff frequency is reported. The extinction ratio is 10 dB for an on-state loss of 4.2 dB. The performance variation with optical power is presented.Keywords
