| Research Abstract |
I have showed by numerical simulation that a hybrid modal-phase-matching and quasi-phase-matching wavelength convertor with laterally inverted core structure can achieve conversion efficiency as high as 47400 %/W in a 53.4-mm-long waveguide and be folded up into a 1.1 mm × 3.5 mm domain. By using surface activation bonding technique at room temperature, I have succeeded in fabricating high-index-contrast AlGaAs/Alox (AlAs oxidation layer) waveguides with laterally inverted core structure. And I have proposed a novel wavelength convertor with laterally inverted structure in order to generate frequency-doubled vector-beam.
