Abstract

A new type of 2×2 fused taper 16 channel wavelength division multiplexer with 20 nm spacing from 1310 to 1610nm was fabricated for application in a multi-channel strain and temperature sensor. The spectral response of each channel under strain and temperature variation was experimentally analyzed. The strain sensitivity in the range of 400-2000με and the temperature sensitivity in 20-100°C were measured. The optical power response to the strain was also measured.
