We fabricated direct-bonded quasi-phase-matched (QPM) LiNbO3 (LN) ridge waveguides for difference frequency generation (DFG) in the 2.7-μm wavelength range, and obtained a conversion efficiency of 87%/W. We showed that dips in the DFG tuning curve originated from the absorption of H2O in air and the O–H absorption in the LN crystal exhibited no influence on DFG when we used the type-0 phase-matching condition. We confirmed that the direct-bonded QPM-LN ridge waveguide is suitable for achieving high-efficiency DFG in the 2.7-μm range.
