Enhancing wavelength selection for Quantum Cascade laser based chemical sensors by cavity length variation

Varying quantum cascade laser cavity length results in gain peak selection across a 118 cm -1 range; a result of a change in threshold voltage, and applied electric field as a function of cavity length.
