Abstract: Abstract In this article, the wavelength of a non-pumped light-emitting diode (LED) is shown to be practically linear with temperature, as a novel consequence of Varshni’s empirical expression. The formula models the bandgap variation for… read more here.

Abstract: We report on thermally tunable modulators, with efficiencies up to 2.16 nm/mW. Efficient performance was accomplished through integrated heater design and Si substrate removal, where the heavily N+ doped Si heater element is integrated into the… read more here.
