| Outline of Final Research Achievements |
For application to laser displays and lithography systems, newly developed electro-optic modulator using spatial light modulators were considered and the prototype was demonstrated. Periodically poled structures for modulation of visible (red, green and blue)lights on a single substrate were designed. By setting the periods of the structures appropriately, the cross-talk level of less than 0.34% was achieved in the calculation. Periodically poled structures were formed in MgO (5 mol%) doped lithium niobate which is suitable for modulation involving high power light. After depositing pixel electrodes for modulation, the modulation signal was applied to the electrodes. The optical intensity modulation corresponding to modulation signals was verified. In addition, preliminary experimental results for high speed modulation with a few GHz were obtained.
