THOMSON TITLE:Study into the spread of heat from thermo-optic silicon photonic elements JOURNAL: OPTICS EXPRESS PAPER DOI IF KNOWN: https://doi.org/10.1364/OE.426748 This dataset contains: Experimentally characterized and simulated data used in the following figures for heat spread from a heating element in Silicon photonics based Thermo-optics Phase shifter. The figures are as follows: Fig.8(a) Temperature line profile across the centre of waveguide cross section (as shown in figure 9) for ΔS= 0, 3, 6, 9 um. Fig.8(b) Percentage temperature change in the waveguide for different waveguide positions in various platforms.
