New class of 1.55 μm quantum dot lasers for future high data rate optical communication

A review will be given on the latest development of highspeed directly modulated 1.55 μm lasers based on high model gain quantum dot material. Static and dynamic properties of short cavity lasers will be presented exhibiting data rates well beyond 20 GBit/s. The impact of structural and operational parameters will be discussed and compared with a simulation model, which includes the complex carrier dynamics in quantum dot laser materials.
