초록

Thermo-optic tunable filter, with 4-pairs of H/L layers for DBR, was designed and fabricated. The transmittance characteristics of the filter were measured. Additionally, heating system and temperature sensor system were used in order to observe property of the filter by thermo-optic effect. The tuning efficiency of the filter was measured to be 0.144nm/K-1 showing the tuning range of 9.4nm for the temperature variation of 64.7oC. Filter, lens and fiber were aligned by micro-optical bench.
