Optical waveguide/grating device for filtering optical wavelengths |
| 摘要 |
A tunable optical filter device has a wavelength selective optical filter that includes a grating structure arranged in a waveguide structure. The grating structure is formed so that it comprises two controllable grating sections electrically isolated from each other and which have different grating periods.
