“…The challenge in achieving on-chip slow and fast light is that the short interaction length requires a very large value of n g to achieve an appreciable pulse delay. Thus far, large values of group index have been obtained using resonances of atomic transitions [3,7] or optical cavities [6,11,14] and multi-structured waveguides [1], however these techniques are fixed in frequency and/or limited in signal bandwidth, constraints which put severe restrictions on the maximum achievable pulse delay. In addition, the atomic transitions for which the largest values of n g are attained require specialized hardware, and have applications mainly in quantum information processing.…”

The ability to control the speed of light on an optical chip is fundamental to the development of nanophotonic components for alloptical signal processing and sensing [1][2][3][4][5][6][7]. However this is a significant challenge, because chip-scale waveguides require very large changes in group index (Δn g ) to achieve appreciable pulse delays. Here, we use Stimulated Brillouin Scattering (SBS) to report the demonstration of on-chip slow, fast and negative group velocities with Δn g ranging from −44 to +130, and delays of up to 23ns at a pump power of ~300mW and propagation length of 7cm. These results are obtained using a highly-nonlinear chalocogenide (As 2 S 3 ) rib waveguide, in which the confinement of both photons and phonons results in strong interaction. SBS can be used to achieve controllable pulse delays at room temperature over a large wavelength and signal-bandwidth [5]. These results open up a new set of photonic applications ranging from microwave photonics [8] to spectrometry [4].

“…2 However, the transmission of spectrally pure, high optical energy through an optical medium requires the consideration and management of nonlinear effects, such as stimulated Brillouin scattering ͑SBS͒. 3 The influences of SBS on optical transmission systems performance and resultant systems impairments is a subject of continued interest and research, 4,5 as photonic based systems become the primary transmissions medium for an increasing number of diverse applications, such as radio over fiber, 6 data synchronizing and buffering, 7 and higher speed telecommunications, to support new domestic services. 8 This also leads to the development of new subsystem components, such as high-Q passband filters, 9 Raman fiber lasers, 10 and erbium doped fiber lasers.…”

To enable optimum network transmission, the ideal is to launch as high laser power as possible into the optical fiber, to overcome the effects of fiber attenuation and maintain an acceptable signal to noise ratio. Launching high powers into a fiber however, results in unwanted nonlinear effects. Stimulated Brillouin scattering (SBS) is one of the nonlinear effects which reflects a significant proportion of the transmitted optical power back to the transmitter, degrading the system severely. This paper reports the development of a digitally selected supermode distributed Bragg reflector monolithic laser chip which can provide significant linewidth broadening using a pure frequency modulation technique by application of a dither current. By modifying a small segment of the laser chip material refractive index, it produces a modulation of the longitudinal mode and hence laser frequency; the monolithic laser chip has reduced the effects of SBS significantly with very little parasitic amplitude modulation.

“…To confirm this expectation, we propagate a super-Gaussian pulse through the SBS system and through the GAB1 system with the system parameters given above. A super-Gaussian pulse is defined using the field amplitude E sg ðtÞ ¼ expð−t α =σ α Þ, where σ ¼ T 0 =2 is the bit half-width at 1=e 2 intensity, T 0 is the bit period, and, for our study, we set α ¼ 4 [16]. Figure 4 shows the result of numerical simulations for the propagation of a pulse with T 0 ¼ 120 ps through these two delay systems.…”

“…Thus, these passive devices can provide delay. The time for which these structures can store energy depends on the cavity parameters [14][15][16][17][18][19][20]. In addition, the bandwidth of these structural resonances depends on the cavity parameters so that the bandwidth and resonance frequency can be tuned.…”

“…Note also that multiple resonator structures can produce a higher delay because the group delay is additive [17,18]. However, these passive devices may suffer from a transmission (or reflection) coefficient less than unity at the resonance frequency, thus requiring amplification of the resulting output signal [15][16][17]. Combining broadband SBS gain-based slow-light systems with these passive devices, therefore, can compensate their respective disadvantages and, thus, increase delay performance without additional pump power.…”

We present a technique for improving the pulse-delay performance of a stimulated Brillouin scattering (SBS) based broadband slow-light system by combining it with fiber Bragg gratings (FBG). We optimize the physical device parameters of three systems: (1) broadband SBS, (2) broadband SBS + a single FBG, and (3) broadband SBS + a double FBG for maximizing the delay performance. The optimization is performed under distortion and system resource constraints for a range of bit rates from 0.5 to 8.5 Gbps. We find that an optimized broadband SBS + a double FBG system improves the fractional delay 1.8 times that of the broadband SBS system at an optimum bit rate of 3 Gbps. Also, pump power consumption is reduced by 15% as compared to the broadband SBS system at the same bit rate.
