Ultrafast Semiconductor Lasers

This lecture discusses the project MIXL, focusing on vertical integration of ultrafast semiconductor lasers for mass production. Ultrafast lasers enable precise control of light flashes, allowing observation of fast dynamics. The potential applications include understanding chemical reactions, fast communication for nanotechnology, and overcoming challenges in electrical interconnects. The current bulky and complex ultrafast lasers can be replaced by more practical semiconductor lasers, particularly vertical emitting ones. By integrating semiconductor saturable absorbers, a single device called the mixer can be created.
