摘要
A 1.65μm three-section Distributed Bragg Reflective (DBR) laser for CH4 gas sensor was reported. Wide tunable range covering R3 and R4 methane absorption line manifolds. Wavelength tunable properties and temperature stability were characterized and analyzed. Several advantages were demonstrated compared with traditional DFB laser in harmonic detection method.
