Description

We present a compact Michelson interferometer-based Fourier transform spectrometer on a silicon photonic chip. In contrast to a conventional Mach Zehnder interferometer (MZI) designs demonstrated elsewhere, our design doubles the optical path difference between the two unbalanced arms of the interferometer thereby effectively doubling the spectral resolution while still maintaining the same geometric length in a MZI. Our design centered at 1550nm thus achieves ~0.8nm spectral resolution with a 40micron geometric path length difference between the two arms of the interferometer in contrast to ~1.6nm spectral resolution in the corresponding MZI. Devices have been fabricated and results will be presented.
