We present work on design of monolithic mode-locked semiconductor lasers with focus on the gain medium. The use of highly inverted quantum wells in a low-loss waveguide enables both low quantum noise, low-chirped pulses and a large stability region.

We have measured steep power transfer characteristics with tunable threshold for a monolithic 2R-regenerator combining amplifying and absorbing sections. Modeling results explain the basic characteristics.

In this paper, we report on a novel technique, which enables clock recovery at 320 Gb/s and relies on a filtering-assisted cross-phase modulation (f-a XPM) in a semiconductor optical amplifier (SOA). This technique is more spectrally efficient than f

We present a novel scheme for optical clock recovery relying on ultra-fast phase modulation in an SOA, enabling locking to single-channel bit rates as high as 320 Gbit/s. Timing resolution and jitter issues are presented. (2 pages)

We demonstrate all-optical label swapping based on SOA, EAM and HNLF for a two-level optically labeled packet using orthogonal ASK/DPSK modulation format. The ASK/DPSK packet is successfully transmitted over 80 km NZDSF.
