  • Increased processing efficiency for optical spectral analyzers
    Patent number: 10295406
    Abstract: An optical spectral analyzer for measuring an optical multi-channel signal by separating the multi-channel signal and measuring a plurality of single-channel signals simultaneously. The spectral analyzer can include a demultiplexer configured to receive the multi-channel signal. The multi-channel signal can be a multi-channel wavelength range. The demultiplexer can separate the multi-channel signal into the plurality of single-channel signals including a first single-channel signal and a second single-channel signal. The spectral analyzer can include a plurality of optical paths. The plurality of optical paths can include a plurality of respective detectors for measuring an optical power of the respective single-channel signals. The detectors can convert the optical power of the respective single-channel signals to corresponding electrical signals.

  • Reversible low-energy data storage in phase change memory
    Patent number: 8467239
    Abstract: A phase change memory (PCM) device utilizes low energy pulses to write data to PCM storage elements (cells). Methods, devices and systems are described that use low energy reset pulses to reset cells that have been previously set using a method that keeps a portion of the PCM cells in an amorphous phase. The reset is reversible by utilizing a low energy set pulse.
