  • Semiconductor laser
    Patent number: 11557876
    Abstract: A semiconductor laser is provided with: an active layer that excites a transverse electric (TE) mode and a transverse magnetic (TM) mode of light and constitutes at least a part of a resonator guiding the TE mode and the TM mode of light; and a diffraction grating as a frequency difference setting structure that sets the difference in oscillation frequency between the TE mode and the TM mode of light higher than a relaxation-oscillation frequency.
    Type: Grant
    Filed: May 28, 2019
    Date of Patent: January 17, 2023
    Assignee: Nippon Telegraph and Telephone Corporation
    Inventors: Nikolaos-Panteleimon Diamantopoulos, Takaaki Kakitsuka, Shinji Matsuo
  • Waveform equalization device
    Patent number: 11418232
    Abstract: An inference processing apparatus includes an input data storage unit that stores pieces X of input data, a learned NN storage unit that stores a piece W of weight data of a neural network, a batch processing control unit that sets a batch size on the basis of information on the pieces X of input data, a memory control unit that reads out, from the input data storage unit, the pieces X of input data corresponding to the set batch size, and an inference operation unit that batch-processes operation in the neural network using, as input, the pieces X of input data corresponding to the batch size and the piece W of weight data and infers a feature of the pieces X of input data.
