Title

Demonstration Of Mid-Infrared Waveguide Photonic Crystal Cavities

Abstract

We have demonstrated what we believe to be the first waveguide photonic crystal cavity operating in the midinfrared. The devices were fabricated from Ge23Sb7S70 chalcogenide glass (ChG) on CaF 2 substrates by combing photolithographic patterning and focused ion beam milling. The waveguide-coupled cavities were characterized using a fiber end fire coupling method at 5.2 μm wavelength, and a loaded quality factor of ̃2000 was measured near the critical coupling regime. © 2013 Optical Society of America.
