| description | The different embodiments of the invention include tunable add-drop and cross connect devices. The add-drop and cross connect devices include materials with negative dependence of refractive index on temperature and temperature independent coincidence between resonator modes and a set of specified frequencies, e.g. for DWDM telecommunications channels. The free spectral range may be adjusted to equal a rational fraction of the specified frequency interval. The operating frequency may be selected without substantially tuning the cavity modes. This can be accomplished by means of a waveguide pair with differential thermal response. |
