Outline of Final Research Achievements

We have investigated the preparation of a cavity polariton system based on the thin layer of organic semiconductor as the active material. We created the cavity mechanically by putting organic thin layer between two high reflective mirrors. The formation of the cavity polaritons was checked by monitoring the angle dependent reflectivity and fluorescence measurements. The vacuum Rabi splitting was estimated to be 300meV at the maximum.
The demonstration of the coherent control of two dimensional distribution of the excited state is performed using solid para-hydrogen as a sample. The two-dimensional distribution of the excited states is designed by modulating the wave front of the pump laser pulses by the spatial light modulator. We have successfully retrieved the 2x2 spot patterns of the excited states and also checked the relative phase factor between the neighboring spots are also maintained in each spot.
