All-fiber pulse compression at 1.32 microm

We have constructed a pulse compressor using two different optical fibers. By adjusting the waveguide dispersion it has been possible to produce fibers with positive and negative dispersion at 1.32 microm. We have demonstrated the compression of 130-psec pulses down to our photodiode limit of 70 psec. This is supported by our calculations, which give a theoretical pulse width of 50 psec. This is the first reported demonstration of both an all-fiber pulse compressor and optical pulse compression at 1.32 microm.
