Abstract
A wavelength selective optical waveguide coupler (1) comprises a first undulatory optical D-fiber (2) and a second optical D-fiber (4) embedded in respective substrates (4,8). The fibers (2,6) are located adjacent one another, the undulations of the fiber (2) defining a set of regularly spaced optical coupling regions. This provides a readily formed coupler able to be accurately set to selectively couple a pre-selected wavelength by relatively coarse macroscopic adjustment.
