Abstract :
Design criteria for relative-phase optical-waveguide modulators are established for single-crystal thin films of zinc sulphide grown on silicon. It is found that the minimum guide length is limited by voltage breakdown to 2 mm while for high frequency applications, because of the leaky nature of the guiding region, the maximum available length and thickness of zinc sulphide are the limiting factors.
