A proposal for an all-optical memory based on a bistability of single-mode states in a dual-mode diode laser with time-delayed optical feedback is presented. The system is modeled using a multimode extension of the Lang–Kobayashi equations with injected optical pulses. We uncover the bifurcation structure by deriving analytical expressions for the boundaries of the bistable region and demonstrate...
We demonstrate low timing jitter 100 GHz passive mode-locking of a discrete mode (DM) laser. This Fabry-Perot device incorporates a spatially varying effective index selecting modes. Near Fourier limited 2.5 ps pulses were obtained.
