On-chip light sources for silicon photonic circuits remain a challenge since the indirect bandgap of silicon prevents efficient light emission. The authors demonstrate that lasing can be achieved by combining standard silicon-on-insulator waveguides

We propose and demonstrate a novel scheme for optical arbitrary waveform measurement (OAWM) that exploits chip-scale Kerr soliton combs as highly scalable multiwavelength local oscillators (LO) for ultra-broadband full-field waveform acquisition. In

Coherent reception becomes an interesting option when data rates in time-division-multiplexed(TDM) passive optical networks (PONs) grow beyond 50 Gbit/s. Controlling the wavelength, i.e., the optical frequency, and the phase of the laser acting as lo
