ABSTRACT:
A system includes a first Fabry-Perot interferometry channel and a second Fabry-Perot interferometry channel serially and optically coupled to the first Fabry-Perot interferometry channel. One channel of the first and second Fabry-Perot interferometry channels has a greater tuning range than the other channel of the first and second Fabry-Perot interferometry channels. The Fabry-Perot interferometry channel having the lesser tuning range has a greater tuning precision than the Fabry-Perot interferometry channel having the greater tuning range. The system may be included in a MEMS-based system, such as a MEMS spectrometer.
