Photonic Crystal Fibers have proved to be an efficient medium for propagation of electromagnetic radiation especially in the Terahertz regime. Located between the infra-red and microwave region, the Terahertz frequency range lies within 0.1 to 1 Terahertz. We report a design of a graduating ring rectangular-core Photonic Crystal Fiber, having background material as Cyclic-Olefin Copolymer (COC), with extremely low confinement loss of 4.9399 × 10−7 dB/cm and material loss of 0.2 cm−1 at 0.22 mm pitch value. Due to the very low loss values, such a structure of the Photonic Crystal Fiber can be used for efficient low-loss data communication.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
