ELECTRICALLY DRIVEN OPTICAL FREQUENCY SHIFTER |
摘要 |
<p>Disclosed herein is an optical frequency shifter (1) provided with: an electro-optical substrate (3) having a main surface (3a); an optical waveguide structure (2) formed in the substrate (3) and having two waveguide portions (7), which are spaced apart by a distance (S) such as to ensure mutual optical coupling therebetween; and an electrode structure (10) arranged above the main surface (3a) of the substrate (3) and having at least a first electrode (11). The substrate (3) has a Z-cut crystalline structure with Z crystal axis orthogonal to the main surface (3a) and comprises two oppositely poled portions (20, 21) having opposite orientations of the Z crystal axis; the two waveguide portions (7) are arranged underneath the first electrode (11), each in a respective one of the two oppositely poled portions (20, 21).</p> |
