摘要
Quantum Cascade devices with an emission wavelength centered around 5 mu m have been shaped into compact, yet long (8 mm and 12 mm) spiral cavities to increase mid-infrared superluminescence (SL) power. Up to similar to 57 mW of SL power at 250 K is obtained with a Gaussian emission spectrum with a full width at half maximum of 56 cm(-1) and a coherence length of similar to 107 mu m.
