Abstract
An optoelectronic component for generating and radiating an electromagnetic signal exhibiting a frequency lying between 30 GHz and 10 THz referred to as a microwave frequency, comprises: a planar guide configured to confine and propagate freely in a plane XY a first and a second optical wave exhibiting an optical frequency difference, referred to as a heterodyne beat, equal to the microwave frequency, a system for injecting the optical waves into the planar guide, a photo-mixer coupled to the planar guide to generate, on the basis of the first optical wave and of the second optical wave, a signal exhibiting the microwave frequency, the photo-mixer having an elongated shape exhibiting along an axis Y a large dimension greater than or equal to half the wavelength of the signal, the injection system configured so that the optical waves overlap in the planar guide and are coupled with the photo-mixer over a length along the axis Y at least equal to half the wavelength of the signal, the photo-mixer thus being able to radiate the signal.
