ABSTRACT
We propose a new two-coupled-waveguide structure for second harmonic generation. An input TEω0 mode is phase matched to a harmonic TM2ω1 mode by varying the separation between the guides. Calculation of conversion efficiency in an AlGaAs structure gives 12% for 10 mW of input power at 1.3 μ over a 2-mm phase-matched length.
