Abstract

The nonlinear process of stimulated Raman scattering is important for silicon photonics as it enables optical amplification and lasing. To understand the dynamics of silicon Raman amplifiers (SRAs), a numerical approach is generally employed, even though it provides little insight into the contribution of different SRA parameters to the signal amplification process. In this paper, we solve the coupled pump-signal equations analytically under realistic conditions, and derive an exact formula for the envelope of a signal pulse when picosecond optical pulses are amplified inside a SRA pumped by a continuous-wave laser beam. Our solution is valid for an arbitrary pulse shape and fully accounts for the Raman gain-dispersion effects, including temporal broadening and group-velocity reduction (a slow-light effect). It can be applied to any pumping scenario and leads to a simple analytic expression for the maximum optical delay produced by the Raman dispersion in a unidirectionally pumped SRA. We employ our analytical formulation to study the evolution of optical pulses with Gaussian, exponential, and Lorentzian shapes. The ability of a Gaussian pulse to maintain its shape through the amplifier makes it possible to realize soliton-like propagation of chirped Gaussian pulses in SRAs. We obtain analytical expressions for the required linear chirp and temporal width of a soliton-like pulse in terms of the net signal gain and the Raman-dispersion parameter. Our results are useful for optimizing the performance of SRAs and for engineering controllable signal delays.

Figures (5)

Fig. 1.
Fig. 1.

Nonlinear reduction factor (NRF) as a function of input power for typical silicon waveguides compared to optical fibers. As the free-carrier lifetime is reduced, NRF increases and approaches the limit determined by TPA (top curve). The right scale shows the enhancement of SRS efficiency in silicon waveguides over silica fibers, obtained by multiplying NRF with the ratio of the Raman gain coefficients for silicon and silica (taken to be 2000).

Fig. 2.
Fig. 2.

Effective length of bidirectionally pumped, 1-cm-long SRA (left panel) and integral intensity (left and right panels) for different contributions of the forward pumping. The green curve on the left panel shows, for comparison, the case of a SRA without nonlinear losses. In the calculations, we used λp = 1434 nm, αp = 1 dB/cm, and τc = 1 ns.

Evolution of maximum signal gain, G = exp[ψ′(L)], in two bidirectionally pumped SRAs for different contributions of forward pumping. The parameters’ values are: λp = 1.434 µm, λs = 1.55 µm, αp = αs = 1 dB/cm, βp = βs = 0.5 cm/GW, and τc = 1 ns.

Evolution of three 10-ps pulses with different temporal envelopes (left panel) and relative energies of the pulses as a function of pump intensity for different values of τ 0 (right panel); W 0 = 1 fJ and I 0 = 1 GW/cm2 in the left panel; η = 100% and τc = 1 ns for both panels. Other parameters are given in the text.

Soliton-like evolution of a Gaussian pulse in (a) forward- and (b) backward-pumped, 1-cm-long SRA. (c) Input FWHM of the soliton-like pulse for 0.2-, 1-, and 5-cm-long SRAs. (d) Evolution of pulse energy as the amount of forward pumping is varied from 100% to zero. I 0 = 1 GW/cm2 in panels (a), (b), and (d); W 0 = 1 fJ and τc = 1 ns for all panels.
