Abstract
A mounting platform provides support and packaging for one or more fiber Bragg gratings and electronic circuitry (e.g., heaters, coolers, piezoelectric strain providers, temperature and strain sensors, feedback circuitry, control loops), which may be printed on or on the mounting platform, embedded in the mounting platform, or may be an “off-board” chip solution (e.g., the electronic circuitry may be attached to the mounting platform, but not formed on or defined on the mounting platform). The fiber Bragg gratings are held in close proximity to the electronic circuitry, which applies local and global temperature and/or strain variations to the fiber Bragg gratings to, for example, stabilize and/or tune spectral properties of the fiber Bragg gratings so that spatial variations in the fiber Bragg gratings that result from processing and manufacturing fluctuations and tolerances can be compensated for.
