Tuning of long-period fibre gratings written by CO2 laser with resonant transmission below -45 dB

Tuning of long-period fibre gratings written by CO2 laser with resonant transmission below -45 dB

Long-period fibre gratings (LPGs) that were made to have resonant transmission below -45dB are tuned via their simultaneous bending and straining. It was found that the position of the LPG resonance can be tuned over more than 6nm, maintaining the level of the resonant transmission below -45dB. Fine tuning of the resonance transmission without a change in its spectral position is also demonstrated. The reported LPGs should satisfy the strictest requirements on the control of LPG filtering characteristics, especially in terms of the phase response.

Abstract

Long-period fibre gratings (LPGs) that were made to have resonant transmission below -45dB are tuned via their simultaneous bending and straining. It was found that the position of the LPG resonance can be tuned over more than 6nm, maintaining the level of the resonant transmission below -45dB. Fine tuning of the resonance transmission without a change in its spectral position is also demonstrated. The reported LPGs should satisfy the strictest requirements on the control of LPG filtering characteristics, especially in terms of the phase response.
