Cascaded Directional Coupler-Based Triplexer Working on Spectroscopically Relevant Wavelengths for Multiple Gas Detection

In this article, we present experimental and simulation results of a novel high-performance cascaded directional coupler-based triplexer. The device is designed to combine the wavelengths of 1530 nm, 1653.7 nm, and 2003 nm for use in spectroscopy systems targeting the detection of ammonia, methane,...
