Abstract :
We report a highly tunable liquid-filled photonic bandgap fiber (LF-PBGF) based on both bend and temperature change. By bending the LF-PBGF and changing its temperature, the blue shift of the red edge of the bandgap resulting from bend loss and temperature increasing is speeded up, and higher bandwidth tunability is achieved. Numerical and experimental results are presented, and 177-nm bandwidth tunability is achieved by tuning the temperature of the LF-PBGF with bend radius of 5 mm from 40°C to 60°C, and the average compression rate is 8.85 nm/°C.
