Abstract :
Summary form only given.Surface-emitted second-harmonic generation (SESHG) offers unique advantages in applications such as ultrafast optical time-division de-multiplexing. In this geometry, efficiency enhancements of one to two orders of magnitude have been demonstrated by resonating the SH in a vertical cavity. In contrast to previous work, we explore, for the first time, the short-pulse regime where the spectral filtering effect of a single cavity mode limits the enhancement. We show experimentally that significant enhancement is possible for pulses shorter than 1 ps, thus allowing efficient, ultrafast, all-optical signal processing and frequency conversion.
