ABSTRACT We demonstrate continuously tunable optical delays as large as 1.1 micros range for 10 Gb/s NRZ optical signals based on four-wave mixing (FWM) process in silicon waveguide. The large delay range is made possible by a novel wavelength-optimized optical phase conjugation scheme, which allows for tunable dispersion compensation to minimize the residual group-velocity dispersion (GVD) for the entire tuning range.

    • "The above motivations led to considerable research efforts on nonlinear silicon photonics in recent years [26] [27] [28] [29] [30]. Nonlinear effects such as SRS [67] [68] [69] [70] [71] [72] [73] [74] [75] [76] [77] [78] [79] [80] [81] [82] [83], self-and cross-phase modulation (SPM and XPM) [84] [85] [86] [87] [88] [89] [90] [91], fourwave mixing (FWM) [92] [93] [94] [95] [96] [97] [98] [99] [100] [101] [102], and supercontinuum generation [60, 61, 103–108] are actively investigated. The main focus is on the near-IR wavelength range, around the telecom window. "

    ABSTRACT: A comprehensive theory is developed for describing the nonlinear propagation of optical pulses through silicon waveguides with nanoscale dimensions. Our theory includes not only the vectorial nature of optical modes but also the coupling between the transverse electric and magnetic modes occurring for arbitrarily polarized opti-cal fields. We have studied the dependence of relevant nonlinear parameters on waveguide dimensions and found a class of waveguide geometries for which self-phase modulation can have a dramatic impact on the polarization state of the optical field. Self-induced polarization changes are studied for both the continuous and pulsed optical fields propagating in silicon waveguides. We also discuss the possibility of using these effects for intensity discrimination and pulse compression.
