Resumo

In this work, we analyze the effect of temperature drifts in a spatial heterodyne Fourier-transform micro-spectrometer fabricated in a Silicon-on-insulator chip. The device comprises an array of 32 Mach-Zehnder interferometers implemented with microphotonic spirals of linearly increasing length. This configuration provides a resolution of 42 pm in a footprint under 12 mm². However, this resolution enhancement implies a greater sensitivity to environmental variations during the spectrometer operation. In this work, the effect of temperature drifts in the spectral retrieval algorithm is studied, and compensation techniques based on multiple calibration matrices is presented
