Ultra high sensitivity chemical photonic sensing by Mach–Zehnder interferometer enhanced Vernier-effect

In this paper an ultra high sensitivity chemical photonic sensor is proposed, employing a Mach–Zehnder interferometer (MZI)-enhanced Vernier effect. The proposed sensor is demonstrated to reach ultra high overall sensitivity (>1000μm/RIU) and very low limit of detection (LOD
