Popis: In this paper, a new technique to attain a tunable parametric amplifier for application in the communication wavelength, based on near-zero ultraflat dispersion with PCF, has been explored. The chromatic dispersion profile and the corresponding zero dispersion wavelength (ZDW) of the optimized PCF can be well tuned to provide a wide gain spectrum in the communication wavelength just by changing the temperature of the fiber. A detailed investigation reveals that the fiber retains its near-zero ultraflat nature when the temperature is increased by 2.50 °C from room temperature. While changing the temperature, the ZDWs can be well tuned, giving rise to a gain region of hundreds of nanometers around the pumping wavelength by changing the temperature of the fiber externally.
