Claim of US Patent No. 10,036,625

1. An integrated, waveguide based, spectrometer implemented in an integrated photonics circuit, the spectrometer comprising:a sensing region configured for receiving multi-wavelength radiation interacting with a sample in the sensing region,
a wavelength demultiplexing element arranged for capturing said multi-wavelength radiation after interaction with the sample and configured for providing a number of wavelength demultiplexed radiation outputs or a number of different groups of wavelength demultiplexed radiation outputs into different signal carriers,
an integrated modulator configured for differently modulating the different demultiplexed radiation outputs or different groups of demultiplexed radiation outputs in the different signal carriers, the integrated modulator being implemented in the integrated photonics circuit, and
a multiplexer element configured for multiplexing the differently modulated demultiplexed radiation outputs or the differently grouped demultiplexed radiation outputs.
