Quantum dots (QDs) enable novel photonic devices like edge and surface emitting lasers, or amplifiers with dramatically improved properties and show potential for optical computers. We have presently demonstrated the extended wavelength range of InAs QDs on GaAs substrate up to 1.5/spl mu/m, large modal gain, high output power, ultralow threshold current, improved temperature stability, reduced linewidth enhancement factor, high frequency operation, hybrid and passive mode-locking presently up to more than 35 GHz, cost-efficient photonic crystal, distributed feedback applications, optical feedback, ultrafast optical amplifiers. These advantages will contribute in the foreseeable future to new cost efficient lightwave communication systems (datacom, MAN, access,..) and probably optical computers.
