Abstract

Abstract: Three different wavelength light sources are coupled to microring circulator via modified add-drop multiplexers, from which the multiplexed signals of them can be formed at the plasmonic islands and used as the distributed sensor nodes. The change in the wavelength due to the external environment will affect the refractive index of the sensing material and hence shift in each wavelength will be seen. Measurements are recorded as the shift in a spectrum (Δλ) by changing the input power and a relationship is obtained between the change in input power and shift in the output spectrum for 1.10, 1.30 and 1.55 μm wavelengths. This is the micro-scale device that can be used for bio-cell content distributed sensors, in which the three different aspects of sensor mechanism can be employed.
