    摘要: An optical modulator comprises an optical input (2); an optical output (14); at least one optical path (6, 8) connecting the optical input (2) and output (14) and means (10, 28) for selectively changing the optical characteristic of a part of the at least one optical path in response to a control signal (Vmod) such as to modulate light passing along the optical path. The optical path further includes a structure (16) which slows the passage of light along the part of the optical path to enhance the modulation effect of the modulator for a given length of optical path. Preferably the structure (16) comprises a sequence of coupled resonator structures in which each resonator structure is defined by a pair of partially reflecting planes (16a, 16b) which define an optical resonator cavity within the optical parts.
