  • Extended bandwidth semiconductor optical amplifier systems and methods
    Publication number: 20050007658
    Abstract: Optical devices and associated production methods are disclosed, one example of such a device takes the form of a semiconductor optical amplifier having first and second ends that at least partially define a signal propagation path. The semiconductor optical amplifier has an active layer that includes multiple quantum well stacks disposed between the first and second ends along the signal propagation path. Finally, the multiple quantum well stacks have a thickness and a width that vary along the signal propagation path.
    Type: Application

  • Extended bandwidth semiconductor optical amplifier
    Patent number: 6791746
    Abstract: A Semiconductor Optical Amplifier (SOA) with extended bandwidth and the method of fabricating the same are disclosed. In one embodiment, the SOA includes a Multiple Quantum Well (MQW) stacks whose thickness varies along the length of the device. The SOA has a flatter and broader gain spectrum than SOAs with substantially flat MQW stacks.
