Fabrication of Two-Dimensional Organic Photonic Crystal Microcavity

A two-dimensional polystyrene photonic crystal microcavity is fabricated by the method of focused ion beam etching. The scanning electron microscopy and the transmittance spectrum are used to characterize the properties of the photonic crystal microcavity. The quality factor and the transmittance of the photonic crystal microcavity is more than 530 and 90%, respectively. The measured results are in agreement with the theoretical predictions.
