ABSTRACT A WAVELENGTH SELECTIVE OPTICAL WAVEGUIDE COUPLER A wavelength selective optical waveguide coupler (1) comprises a first undulatory optical D-fibre (2) and a second optical D fibre (4) embedded in respective substrates (4,8). The fibres (2,6) are located adjacent one another, the undulations of the fibre (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.
