Investigation on an optically-controlled phase-shifter based organic semiconductor poly-(3-hexylthiophene) (P3HT)

摘要

In this paper, an investigation on opticallycontrolled phase-shifter based organic semiconductor P3HT is presented. The operation principle of optically-controllable phase-shifters and the applicability of organic semiconductor P3HT to such devices have been demonstrated. The reversible, optically-controlled phase-shifter employing P3HT as an active device layer, yielded differential phase shifts which varied with light intensity and signal frequency as well as device architecture. The results are non-optimized, and impedance matching needs to be improved in the future in order to obtain better signal transmission performance through the device.
