Wavelength calibration of a fiber-optical spectrum analyzer: temperature dependence.
Optical spectrum analyzers are of increasing importance in fiber-optic laboratories. To perform reliable measurements with these devices, one must calibrate them with respect to wavelength, resolution bandwidth, power, etc. and know the temperature dependence of such calibrations. We have constructed a temperature-controlled chamber that can contain a spectrum analyzer and that can be regulated to within +/-0.1 degrees C. We report the temperature dependence of wavelength calibration and compare the various calibration results performed under temperature control with those previously obtained at ambient nonregulated temperature. For these studies we have used a compact calibration artifact based on absorption spectroscopy of acetylene.
