Intensity Modulation Response of a Quantum Cascade Laser Emitting Light of 9 Micrometer Wavelength

摘要

We have recently improved a two level model of a quantum cascade laser. The two level model is simpler than the 3-level model reported earlier. We calculated the intensity modulation of a laser emitting light of wavelength 5 μm. As the laser considered is rather old, we consider a more recent quantum cascade laser and examine its intensity modulation response.
