Here we demonstrate the electro-optic modulation and tuning of single-crystalline organic microring resonators. We patterned the corresponding waveguide structures equipped with lateral electrodes into a borosilicate wafer using optical lithography. Subsequently the volume of the waveguide layout was delimited by anodically bonding a cover wafer to form channels where the melt of COANP (2-cyclo-octylamino-5-nitropyridine) flowed in and crystallized. The organic microring resonators with typical cross-sectional waveguide dimensions were characterized by transmission and electro-optic modulation experiments. The electro-optic properties of COANP microrings have been tested by shifting the transmission spectrum applying a static electric field to the device electrodes. This wavelength shift corresponds to a frequency tunability of 0.11 GHz/V, which is comparable to what has been reported for ion-sliced LiNbO3 microring resonators.
