Abstract :
We demonstrate a tunable wavelength filter based on Solc-type effect in linearly chirped quasi-phase-matched structure. The experimental result shows the central wavelength of the bandpass dependent on the temperature is 0.6 nm/°C in chirped QPM structure, which equals to that of the periodic QPM structure. The bandpass width can be controlled by the amount chirp of QPM structure.
