Paper Abstract

We describe reverse-proton exchanged (RPE) waveguides in MgO-doped lithium niobate capable of stable secondharmonic generation (SHG) of over 100 mW of CW green light with conversion efficiency exceeding 200%/Wcm2. Substantially higher green power would require careful thermal management to limit the phase mismatch due to heating produced by optical absorption. RPE waveguides show ability to support high-power generation of green light superior to anneal-proton exchanged (APE) waveguides containing a higher-index layer. We also demonstrate devices with multipeak spectral response for speckle-reduced green laser by using phase-modulated, quasi-periodic ferroelectric domain structure.
