Mid-IR optical amplifications using resonant gain of quantum cascade lasers Conference Paper uri icon

abstract

  • Using quantum-cascade-lasers (QCL) as resonant optical amplifiers, active filters, and detectors with gain, we demonstrated signal amplification in the mid-IR wavelength range. Optical gain of >10dB and electrical gain of >28dB were achieved. © OSA 2012.
