  • Abstract
    The authors report thermo-optical switching in a 92 layer Si/Si 0.7Ge0.3 distributed Bragg reflector (DBR) grown by molecular beam epitaxy. Depending on the layer periodicity, this structure exhibited a positive or negative reflectivity switching λ=1.06 μm, with a switch-on time of less than 20 ns and reflectivity contrast ratios greater than 50%
