The cavity consists entirely of fiber waveguide, permitting an extremely wide range of possible Free Spectral Ranges (FSRs), and no alignment or mode-matching is required. Wavelength scanning is achieved by axially straining a short section of fiber inside the cavity using a stacked piezoelectric actuator. Scanning frequencies to 100 Hz and higher can provide direct measurement of transient optical phenomenon such as laser chirp and jitter. Stable and repeatable scanning over longer periods of time can provide direct measurement of slowly varying optical phenomenon such as laser drift. For driving the FFP-SI, the FFP Controller (FFP-C) provides simple electrical signals for wave- length scanning and wavelength selection in either open or closed-loop mode. Many spectral measurements can be made using only an FFP-SI, FFP-C and oscilloscope. Also the FFP-SI can be cascaded with other FFP-SIs or FFP-TFs to provide ultra-high finesse values. In general, FFP-SIs are sensitive to the input polarization of the optical signal. Since polariza- tion properties of the FFP-SI are stable, an input polarization controller can be used to tune to one polarization or to perform polarization analysis. TUNED Products displaying the "Micron Optics Tuned" logo include Micron Optics tunable technologies insuring high quality and performance.

oooo oooo Fiber Fabry-Perot Scanning Interferometer FFP-SI Specifications FFP-SI 1. Each useful spectral range defined by mirror pass band. 2. Measurable bandwidth is limited by laser linewidth used for device characterization. 3. Typical value; final value depends on Free Spectral Range and Finesse. 4. Maximum input power level depends on finesse value. Generally, the higher the finesse, the lower the maximum input power level.
