Query: Infrared Supercontinuum Generation in Multiple Quantum Well
  Nanostructures under Electromagnetically Induced Transparency   Mid-infrared spectral broadening is of great scientific and technological
interest, which till date is mainly achieved using non-silica glass fibers,
primarily made of tellurite, fluoride and chalcogenide glasses. We investigate
broadband mid-infrared supercontinuum generation at very low power in
semiconductor multiple quantum well (MQW) systems facilitated by
electromagnetically induced transparency. 100 femto-seconds pulses of peak
power close to a Watt have been launched in the electromagnetically induced
transparency window of a 30 period 1.374 {\mu}m long MQW system. Broadband
supercontinuum spectra, attributed to self phase modulation and modulation
instability, is achievable at the end of the MQW system. The central part of
the spectra is dominated by several dips and the far infra-red part of the
spectra is more broadened in comparison to the infra-red portion. Key advantage
of the proposed scheme is that the supercontinuum source could be easily
integrated with other semiconductor devices.
