Method and apparatus for thermo-optic modulation of optical signals |
摘要 |
The present invention is a method and an apparatus for thermo-optic control of optical signals using photonic crystal structures. In one embodiment, a first portion of a split signal is modulated by propagating the signal through a photonic crystal waveguide in which two electrical contacts are laterally spaced from the waveguide region by a plurality of apertures formed through the photonic crystal substrate. A voltage applied across the electrical contacts causes resistive heating of the proximate photonic crystal waveguide through which the signal propagates, thereby modulating the temperature relative to an un-modulated second portion of the split signal that is used as a reference.
