Abstract

Based on the evanescent-field coupling between the cladding modes of two adjacent and parallel all-fiber acousto-optic tunable filters, tunable broadband light coupling with relatively uniform insertion loss of trapping spectrum was achieved. In the experiments, a wide spectral tuning range from 1490 nm to 1610 nm, covering the whole C- and L-band and parts of S-bands, was demonstrated with a wavelength tunability slope of −0.72 nm/kHz. The insertion loss of the trapping spectrum was uniform (around −5.0 dB, which can be improved with a longer evanescent-field coupling length) within the whole tuning spectral range. Such a light coupling structure would be useful in tunable broadband light coupler and broadband optical fiber add/drop multiplexer for applications in coarse wavelength division multiplexing systems.

Experimental configuration of the light coupling between two parallel AOTFs. LAO1 and LAO2: the length of the acousto-optic interaction regions of AOTF1 and AOTF2, respectively; LC : the length of the evanescent-field coupling region which is supported by a low-index MgF2 substrate and dipped inside the refractive-index-matched liquid. RF: the driving radio frequency sources.

Fig. 2

Transmission spectra of the two AOTFs when the AOTF1 and AOTF2 were driven by two independent RF driving signals with the same driving frequency f=0.9795 MHz but different driving powers P=8 dBm and 9 dBm, respectively.

(a) The black and red curves denote the output spectra of Port2 and Port3, respectively, when light was coupled into Port1. (b) The blue and green curves denote the output spectra of Port4 and Port1, respectively, by coupling light into Port3.

The central wavelength tunability of the transmission and trapping spectra from Port2 and Port3. (a) The central wavelength was at λ =1490 nm, 1510 nm, 1530 nm, 1550 nm, 1570 nm, 1590 nm and 1610 nm when the RF driving frequency f = 1.066 MHz, 1.036 MHz, 1.008 MHz, 0.9795 MHz, 0.9535 MHz, 0.9270 MHz and 0.9001 MHz, respectively, was applied to the two parallel AOTFs. (b) The central wavelength versus the RF driving frequency applied to the two parallel AOTFs. The central wavelength tunability slope was measured to be −0.72 nm/kHz.
