Resumen
We present a tunable optical delay line based on the use of a
single chirped fiber Bragg grating written into a standard single mode
optical fiber. In the proposed scheme, the delay is induced through the
Bragg grating differential group delay curve. This is achieved by launching
orthogonally polarized optical pulses in both directions into the Bragg
grating and by controlling its local birefringence. This bidirectional
propagation allows to compensate the second-order dispersion. The setup is
suitable to delay pulses with a spectral width just less than the grating
reflection bandwidth, which is particularly useful in the context of
forthcoming wavelength division multiplexing ultra-high bit rate lightwave
systems. In this work, the performances of the setup are investigated using a
pulsed laser delivering 6.3 ps Fourier transform limited pulses at 1548 nm.
A maximum delay of 120 ps (about 20 times the pulse width) is reported
experimentally.
