Electric Field Induced Second Harmonic Generation in Germanium Doped Silica Planar Waveguides
FRANK J SEILER RESEARCH LAB UNITED STATES AIR FORCE ACADEMY CO
Pagination or Media Count:
Instantaneous frequency doubling is demonstrated in germania doped silica planar waveguides deposited on fused silica substrates by quasi- phasematching with an externally applied, periodic DC field. The DC field periodicity which causes frequency doubling corresponds to the beat length between the fundamental and second harmonic light propagating in the waveguide.
