Silicon nanophotonic state #3
To control the speed of light electrically two lateral electrical contacts are deposited on top of a silicon membrane. This forms an integrated microheater. The trick is to position the contacts as close as possible to the waveguide core and, at the same time, to avoid excessive parasitic losses due to absorption in metal.
