Abstract
An electro-optical (EO) modulator that includes (i) a substrate. (ii) a modulation unit that includes an EO modulation layer and a modulation zone waveguide that is optically coupled to the EO modulation layer and is partially surrounded by one or more gaps. (iii) radio-frequency electrodes that are electromagnetically coupled to the EO modulation layer. (iv) an input waveguide that is configured to guide light towards the modulation unit; and (v) an output waveguide that is configured to receive modulated light from the modulation unit.
Claims21
An electro-optical (EO) modulator, comprising:
- a substrate;
- a modulation unit that comprises an EO modulation layer and a modulation zone waveguide that is optically coupled to the EO modulation layer and is partially surrounded by one or more gaps;
- radio-frequency electrodes that are electromagnetically coupled to the EO modulation layer;
- an input waveguide that is configured to guide light towards the modulation unit;
- and
- an output waveguide that is configured to receive modulated light from the modulation unit.
A method for electro-optical (EO) modulation, the method comprising:
- guiding, by at least an input waveguide of an EO modulator, light towards a modulation unit of the EO modulator, the modulation unit comprises an EO modulation layer and a modulation zone waveguide that is optically coupled to the EO modulation layer and is partially surrounded by one or more gaps;
- modulating the light, by the modulation unit, under a control of radio-frequency electrodes that are electromagnetically coupled to the EO modulation layer, to provide modulated light;
- and
- outputting, by at least an output waveguide of the EO modulator, the modulated light.
