The large signal dynamics of passively colliding pulse mode-locked laser diodes is studied.
We derive a model which explains modelocking via the interplay of gain and loss dynamics; …

Multiple colliding pulse mode-locked operation where 3 or 4 ultrashort pulses are present
simultaneously within a semiconductor laser is described. Frequency and time domain …

Semiconductor lasers have the potentia! to become compact sources of very high repetition
rate subpicosecond optical pulses. Using external cavities, semiconductor lasers have been …

We report here on a monolithic multisectioned quantum-well laser that operates as multiple
colliding pulse mode-locking source. With this type of operation several pulses are present …

We describe the first results of hybrid mode locking combining both active and passive mode
locking of a semiconductor laser. These functions are integrated into a monolithic device …

A scheme to produce single optical sub-picosecond pulses by hybrid mode locking of an
external cavity laser at a repetition rate of approximately= 1 GHz is demonstrated. In order to …

It is shown that although it is possible to obtain mode-locking without self-pulsation when
certain criteria are satisfied, the shortest pulses are almost always generated at or close to …
