Simultaneous measurement of absorption and scattering losses in bulk glass and optical fibers by a microcalorimetric method

When light is launched into either an optical fiber or a bulk glass rod, discrimination of scattered and absorbed energies is possible through the different thermokinetics of these phenomena. The design and performance of a differential calorimetric arrangement are presented and simultaneous measure...

Description
Summary:When light is launched into either an optical fiber or a bulk glass rod, discrimination of scattered and absorbed energies is possible through the different thermokinetics of these phenomena. The design and performance of a differential calorimetric arrangement are presented and simultaneous measurements of the various loss coefficients are reported. At the present time, sensitivity is of the order of 1 dB/km and can be further improved.
