Integrated-optics components: Modulators and deflectors

This paper constitutes a review of the progress made in developing integrated optics (IO) modulators and deflectors. This is now a sizeable group of devices, ranging from IO analogs of bulk Pockels effect and acoustooptic modulators and deflectors, to directional coupler modulators and switches unique to guided wave devices. Although maximum advantage from the use of these components will probably be realized in combination with other guided wave components, i.e., in integrated optics circuits, some will find a place as separate components because of the characteristically low power requirements and small size.
