Abstract

It is theoretically demonstrated that a succession of four unchirped gratings, ~20 mm long, induces a negative chromatic dispersion in transmission of −100 ps/nm over a 0.2-nm bandwidth, with a power loss below 1 dB. The stability of the proposed arrangement is also considered and found to be within today’s technology.

Figures (4)

Fig. 1
Fig. 1

Converted power from modes LP01 to LP02 by unchirped gratings as a function of wavelength. The following fiber characteristics are assumed (near λ = 1550 nm): Propagation constant difference between the two modes, Δb = 2π/100 1/μm. This corresponds to a step-index fiber of 0.022 at λ = 633 nm and a core radius of ~4 μm.

Fig. 2
Fig. 2

CD and converted power for the configuration of the two gratings shown above. The gratings are the same as in Fig. 1. The group-delay difference between the two modes is ΔGrDelay = 50 ps/m. Cases of three distances between the beginning of the gratings are illustrated: D12 = a, 310.040, b, 270.040, c, 230.040 mm.

Fig. 3
Fig. 3

Relative power converted from LP01 to LP02 by the pair of gratings A and B. This pair of gratings replaces gratings 1 and 2 of Fig. 2. The gratings are identical, unchirped, with a length of 20 mm, a step size of 100.0 μm with a precision of ~0.1 μm, and a coupling constant κ = 0.075 lines/mm. In curve C1, D = 100.025 mm; in curve C2, D = 100.075 mm, where D is the distance between the beginning of the gratings.

Fig. 4
Fig. 4

CD and converted power for the four-grating configuration. All gratings are identical: length, 20 mm, κ = 0.075 lines/mm, grating step size 100 μm. The distances between the beginnings of the gratings are 120.025, 190.004, and 120.025 mm. Note that the output beam is in mode LP01 and that no compensated intensity remains in mode LP02.
