Abstract
We present the fabrication and characterization of an integrated structure comprising a Kerr non-linear fiber with in-line bragg grating for ultra-fast all-optical switching at laser diode power levels. A cross-sectional view of the structure is shown in Figure 1. The operation of the device is based on intensity induced wavelength shift of a probe signal in the Kerr fiber. The structure is designed such that the transmission wavelength of the grating coincides with the probe wavelength. Thus in the absence of a pump pulse, the probe is transmitted by the grating. This corresponds to the ON-state of the switch. At a critical pump intensity there is a shift in the wavelength of the probe equal to the band stop wavelength of the grating. As a result the probe signal is reflected by the grating. This corresponds to the OFF-state of the switch.
