Highly sensitive sensor based on 4×4 multimode interference coupler with microring resonators
This study proposes a novel optical integrated structure using only one 4x4 multimode interference (MMI) coupler with support of two microring resonators for glucose and ethanol sensor. Due to the presence of the analyte, the wavelength shift of the output spectrum is realized. The proposed structur...

| الملخص: | This study proposes a novel optical integrated structure using only one 4x4 multimode interference (MMI) coupler with support of two microring resonators for glucose and ethanol sensor. Due to the presence of the analyte, the wavelength shift of the output spectrum is realized. The proposed structure can provide a high sensitivity of 721 nm/RIU, low detection limit of 2.8x105 and good figure of merit of 5x1016 for glucose sensing. |
