| 摘要 |
The invention relates to an optoelectronic component (30) for generating and radiating an electromagnetic signal (S) having a frequency (F) comprised between 30 GHz and 10 THz, i.e. what is referred to as a hyperfrequency, comprising: a planar guide (Gp) configured to confine and to allow to freely propagate in an XY plane first and second optical waves (O1, O2) having an optical frequency difference, denoted the heterodyne beat, equal to said hyperfrequency (F); a system (Si) for injecting said optical waves (O1, O2) into said planar guide (Gp); and a photo-mixer (PM) coupled to said planar guide (Gp) so as to generate, from the first optical wave (O1) and the second optical wave (O2), a signal (S) having said hyperfrequency (F), said photo-mixer (PM) having an elongate shape having, along a Y-axis, a large dimension (L) larger than or equal to the half-wavelength (λF) of said signal (S), said injecting system (Si) being configured so that said optical waves overlap in said planar guide and couple to the photo-mixer (PM) over a length along the Y-axis at least equal to the half-wavelength (λF) of said signal (S), the photo-mixer thus being able to radiate said signal (S). |
