This paper presents a simulation and investigation about the nonlinear interplay between an optical pulse and GaAs waveguide. The results obtained show that the nonlinear processes including self-phase modulation, 2-photon absorption, and free carrier related effects will have significant influences on the temporal shape and frequency spectrum of a propagating pulse in the GaAs waveguide with the result that 2-photon absorption can extend the pulse duration that can be again compressed by the free carrier absorption. The outcome spectrum is also asymmetrical due to the free carrier related effects, which takes on a complicated oscillation structure resulting from the interference. In addition, an interesting phenomenon is that the input pulse will eventually evolve into a double pulse along the GaAs waveguide by means of judiciously adjusting the intensity, waveform, and time duration of the input pulse, i.e. when the time duration of the input pulse is larger than the carrier lifetime, the input pulse with high enough intensity can develop into a double pulse at the end of the waveguide.

“…Apiratikul et al [64] have demonstrated wavelength and format conversion at 10 Gbit/s, from NRZ-OOK to RZ-OOK based on FWM in a passive GaAs bulk-waveguide. A conversion efficiency of 28 dB over a 48 nm bandwidth was achieved and demonstrates the viability of GaAs waveguides for nonlinear optical signal processing.…”

“…[17][18][19][20][21] approaches have been explored. Most of the investigated all-optical approaches employed semiconductor optical amplifiers (SOAs) and very few used other devices such as periodically poled lithium niobate waveguides [22], silicon waveguides [3], III-V waveguides [16] and III-V ring lasers [23]. All-optical data format conversion devices based on SOAs have a large footprint with the cavity length of a single SOA varying from several hundreds of micrometers to a few tens of millimeters, e.g.…”

Abstract:We report the demonstration of an all-optical, bias free and errorfree (bit-error-rate ~10 -12 ), 10Gbit/s non-return-to-zero (NRZ) to return-tozero (RZ) data format conversion using a 7.5µm diameter III-V-on-silicon microdisk resonator. The device is completely processed in a 200mm CMOS pilot line. The data format conversion is based on the phenomenon of pulse carving of an NRZ optical data stream by an optical clock. The underlying physical effect for the pulse carving is the change in the refractive index caused by the generation of free-carriers in a pump -probe configuration. We believe it to be the first NRZ-to-RZ format convertor built on a hybrid III-V-on-silicon technology platform. References and links 1.D. Norte, E. Park, and A. E.
