Abstract
Because the band gap of semiconductors is temperature dependent, so too are the gain spectrum and refractive index of optoelectronic components, such as diode lasers, filters, modulators, and routers. Indeed, in these devices, the refractive index is dominated by the absorption at the band edge, and if the bandgap is stabilized against temperature fluctuations, the refractive index is also stabilized.
