摘要：
A spectroscopic analysis device for analysis of a sample comprising: a photonic integrated circuit (PIC) comprising: an input (DEF) for receiving light from the sample； and a demultiplexer (DEMUX) arranged to distribute the received light into at least a first optical chain (C1) and a second optical chain (C2)； wherein each optical chain (C1, C2) of the photonic integrated circuit (PIC) further comprises a tunable bandpass filter (TBF1, TBF2) and a variable attenuator (ATT1, ATT2) and a photodetector (PD1, PD2) arranged respectively to filter and to attenuate and to detect the light distributed into its corresponding optical chain (C1, C2).
