Abstract

In this paper a four-channel OADM based on fiber gratings with smart temperature stable sets was implemented. It solved the conflict between the tunable capability and the temperature stability of the center wavelength. Using a cantilever beam method, the tunable range of 1nm is obtained. Within the temperature range -20°C ~+ 60°C, the center wavelength shift is less than 0.004 nm/°C and the thermal stability is 6.75 times as that without thermal stable sets. The wavelength spacing is 0.8 nm, which accords with ITU-T G.692 recommendation. 35 dB of the adjacent isolation in the OADM is obtained, which is the best one reported as we known.
