We present theoretical results for short-pulse surface-emitted second-harmonic generation and show that significant cavity enhancement is possible in the femtosecond regime. Experimentally, we demonstrate enhanced surface-emitted second-harmonic generation using 200 fs fundamental pulses near 1.5 μm by use of a 5λ[sup SH]/2n vertical microcavity in [211]-oriented AlGaAs waveguides. The microcavity height is minimized by allowing the distributed Bragg reflectors that define the vertical cavity to also serve as cladding layers for the fundamental waveguide, thereby increasing the resonance width and hence the overlap with the second-harmonic spectrum. © 2001 American Institute of Physics.
