Abstract

An integrated waveguide based spectrometer is described. The spectrometer comprises a sensing region for receiving multi-wavelength radiation for irradiating a sample in the sensing region, a wavelength demultiplexing element arranged for capturing said multi-wavelength radiation after interaction with the sample and for providing a number of wavelength demultiplexed radiation outputs or a number of different groups of wavelength demultiplexed radiation outputs, an integrated modulator for differently modulating the different demultiplexed radiation outputs or different groups of demultiplexed radiation outputs, and a multiplexer element for multiplexing the differently modulated demultiplexed radiation outputs or the differently grouped demultiplexed radiation outputs.
