Optical Signal Processing Using Tunable Delay Elements Based on Slow Light

Dynamic modeling of slow light in tensile-strained semiconductor optical amplifiers

“…Slow light occurs when a propagating pulse is substantially slowed down by the interaction with the medium in which the propagation takes place. The use of slow light has potentially important applications in optical buffering [2] and delay lines [3] and in microwave photonic applications such as tunable phase shifters [4]. In an SOA the principle mechanism causing the slow light effect is coherent population oscillations (CPOs), whereby beating between two lightwaves leads to carrier density oscillations at the beat frequency.…”

Time delay reduction in low power ultrashort pulse and pulse stream propagation with overlapping soliton pair

“…[9][10][11] Therefore, controlling or decreasing time delay is an important aim in some researches. [12][13][14] These methods usually involve external devices, which may impose additional noise to the ultrafast applications.…”

Numerical investigation of system performance in SBS slow light using filtered incoherent pump

“…Slow light and its applications into nonlinear signal processing have gained substantial interests [1][2][3][4][5][6][7][8][9][10] since the first few demonstrations [1][2][3]. One of the major applications for slow light is to generate tunable delays in advanced optical networks, especially through stimulated Brillouin scattering (SBS) in optical fiber itself [4][5][6][7], as elements based on such mechanism are promising candidates in high-speed all-optical networks and signal processing applications.…”
