1 m long continuously-written fibre Bragg gratings for combined second- and third-order dispersion compensation

Abstract

The authors present the realisation of high-quality 1 m long continuouslywritten fibre Bragg gratings designed to compensate both 2nd and 3rd order fibre dispersion. These compact devices are ideal for counteracting the effects of fibre dispersion in high bit-rate transmission systems.

A comparative study of the performance of seven- and 63-chip optical code-division multiple-access encoders and decoders based on superstructured fiber Bragg gratings

“…Note that previous work has indicated that dispersion-slope correction can in certain instances also be an issue for such broadband spread-spectrum transmission schemes since it can serve to skew the chip alignment in the decoded signal [21]. No such effects were apparent in our current experiments; however, it should be appreciated that thirdorder dispersion compensation can also be incorporated into the design of dispersion compensating Bragg gratings if required [22], [23]. As mentioned previously, the dispersion compensating grating used in our experiments was also fabricated using the same technique and with the same phase mask used to fabricate the coding/decoding SSFBGs.…”

Optical temperature sensing on flexible polymer foils

“…Subsequently, fiber Bragg gratings became one of the most important passive fiber optic components, used for dispersion compensation [9][10][11][12], fiber laser pump reflectors [13][14][15] and in various sensing applications. Sensing fields such as strain [16], pressure [17][18][19], ultrasonic waves [20][21][22], force [23][24][25], acceleration [26,27], magnetic field [28,29], and temperature [30][31][32] were covered by FBGs over the years.…”

Automatic DGD and GVD compensation at 640 Gb/s based on scalar radio-frequency spectrum measurement

“…Compensation schemes for multiple orders of dispersion are well known and include the use of phase modulators [8], tunable fiber Bragg gratings [10][11][12], and concatenation of spans of specialty fibers [13,14]. However, fluctuations of the impairments, mainly due to temperature drifts and stress variations, also occur in long-distance fiber transmission, requiring adaptative solutions able to tune the compensation in real time [15][16][17].…”
