Multi-soliton generation with extremely narrow free spectrum range for multiplexed sensors via optical network

We propose a new system of multiplexer sensors using the localized soliton pulse generated by a microring resonator in optical networks. A large bandwidth signal is generated by a soliton pulse propagating within the microring resonator, which is allowed to form the multiplexed sensors. Two forms of soliton pulses are generated and localized, i.e. temporal and spatial solitons. The required soliton pulses with specified wavelengths can be localized and formed the sensing. This is formed by using an optical add/drop multiplexer incorporating in the optical network, where the localized soliton pulses are available for add/drop signals to/from the optical network. The change in physical parameter measured the change in soliton wavelength, which formed the measurement.
