“…He went on to show that this effect could be minimized by decreasing the coupling coefficient gradually toward the ends of the coupling region. It was also demonstrated in a more recent experimental study [6] that apodization of the linearly chirped grating leads to reduce side lobes and hence the reduction of unwanted in the dispersion delay ripple as well.…”

A finite one-dimensional, linearly Bragg grating with chirp parameter C and index modulation depth n1 or coupling constant κ ∝ n1is considered for numerical analysis of its performances by converting its coupled equations into a confluent hypergeometric equation. The operational parameters considered for the analysis consist of the group delay, the reflectance (R), the reflectance ripple (RR), the reflectance bandwidth (BW) and the group delay ripple (GDR). It is shown that increasing C leads to decreasing GDR and increasing BW which are favorable to the device performance. However, the RR is relatively unaffected while R suffers from an undesirable diminution. On the other hand, increasing κ results in the enhancement of R and BW while reducing RR when κ is increased beyond a certain turning point. But these are attained at the expense on enlarged GDR. The results of this study clearly points to the need of compromising between C and κ for the optimal operation of the device.

“…(Hill et al, 1994) The DCF is a long section of fiber with significant loss and high non-linearities due to its small core diameter. The chirped FBG is a compact, all-fiber device with a short interaction length and low non-linearities.…”

“…It was noted, however, that the performance of such systems was severely limited by fiberinduced group-velocity dispersion, which caused the different bits to travel at different velocities ͑also called bit skew͒. Since then, however, the idea of managing dispersion with one of several methods including dispersion-compensating fiber, 2 chirped fiber gratings, 3 or phase conjugation 4 has become a practical reality. Consequently, the concept and potential attributes of a spectral bus should once again be revisited.…”

We present experimental results on a new method for ultrafast all-optical logic, which utilizes four-wave mixing on polarization-modulated signals. The technique allows advanced operations such as exclusive-OR and three-bit addition with carry bit. Furthermore, we show that on-the-fly errorcorrection encoding and decoding of a simple Hamming code is achieved when these gates are used on the bits of a spectrally structured word. These gates may be suitable for logic operations in an optoelectronic front end, which moves some of the necessary computation of data to the optical domain, before detection.

Chirped in-fiber Bragg gratings for compensation of optical-fiber dispersion

Abstract: A linearly chirped in-fiber Bragg grating is reported that can compensate at 1549 nm for the dispersion [ approximately -19 ps/(nmkm)] of standard telecommunications optical fiber optimized for 1300-nm operation.
