This letter describes the design, fabrication, and characterization of an air-mode 1-D photonic crystal resonator (PCR) operating at 100 GHz. The PCR was fabricated from an inexpensive cyclic olefin copolymer (COC) using computer numerical control (CNC) milling. It is demonstrated that despite the lack of complete electromagnetic bandgap arising due to the low permittivity of the COC, it remains possible to realize a resonator with a high quality factor ( $Q$ -factor) of 2800 through shaping of the resonant field to minimize radiative loss.
