Research Abstract

This study has been pursued to develop electro-optical ultrashort optical pulse generation method with high controllability. A main results obtained are as follows ;
1) Design and improvement of an electrooptic phase modulator/deflector with high-modulation index using periodic domain inversion scheme.
We succeeded in development of compact size waveguide-type quasi-velocity-matching electrooptic modulator with periodic domain inversion. Highly-efficient phase modulation as compared with a bulk-type one has been experimentally confirmed.
2) Proposal of a novel QVM optical phase-modulator featuring lens modulation and its application to the electrooptic chirping compression method for pedestal free femtosecond optical pulse generation.
Ordinary sinusoidal phase modulation generates both types of the frequency chirping ; up-chirping and down chirping. There was, therefore, a problem that although short optical pulses are obtained from one of chirping part by chirping compression method with the group delay dispersion, other chirping part still remains as background light. Our new modulator has lens modulation function as well as phase modulation function. Since modulated light beam is focused into the different point for the case of up-chirping and down-chirping, respectively, we can easily eliminate the undesirable chirping part by a pinhole. Using this modulator we succeeded in generation of pedestal free 520fs pulses from a cw Ar laser.
3) Proposal and design of novel Fabry-Perot electrooptic modulator accompanied with lens modulation for femtosecond pulse generation. (Jpn Patent pending, H10-258293, CLEG '99 to be presented).
