An optically controlled phase shifter employing the organic semiconductor poly(3-hexylthiophene)

摘要

The transmission characteristics of optically controlled phase shifters employing the organic semiconductor poly(3-hexylthiophene) (P3HT) are reported. Two microstrip structures were fabricated onto a P3HT coated indium tin oxide substrate supported by glass. Experimental results on these unoptimized prototype structures yield reversible differential phase shifts > 10° at 2.0 GHz under tens of milliwatt optical power illumination. These devices demonstrate great potential as linear analog phase shifters.
