  • Patent number: 7671997
    Abstract: A superluminescent diode according the present invention employs a uniform AlGaInAs quantum well on an InP substrate, emitting in a range of 1100 to 1800 nm. The favorable conduction band: valence band offset ratio of this material system enables superluminescent diodes which simultaneously provide high power and large optical bandwidth. A recent reduction to practice of the present invention simultaneously demonstrates output power exceeding 100 mW and bandwidth exceeding 100 nm. A preferred embodiment of this invention uses multiple uniform AlGaInAs quantum wells with two confined quantum states and energetic separation in a range of 100-130 nm. An alternate preferred embodiment uses non-uniform wells, with each well having two confined quantum states. The present invention is particularly useful in time domain and spectral domain optical coherence tomography systems, providing increased resolution and tissue penetration for in-vivo imaging.

  • Publication number: 20080240107
    Abstract: Systems and methodologies are described that facilitate maintaining consistent radio-link layer protocol (RLP) sequence numbers in the event of an RLP sequence number reset. An offset can be adjusted upon occurrence of the event to reflect a subsequent expected sequence number. The offset can be added to the RLP sequence numbers such that receiving devices and/or higher layer applications can operate without realizing the sequence number reset. Additionally, the offset can be synchronized among base stations to facilitate operability following handoff of the receiving device.
