  • Enhancing the bandwidth of light sensors on planar optical devices comprising a light sensor configured to output a passed light signal and to receive at least a portion of the passed light signal
    Patent number: 10191231
    Abstract: The optical device includes a light sensor positioned on a base. The light sensor is configured to receive an input light signal and outputs a passed light signal that includes light from the input light signal. The optical device also includes a return system located on the base. The return system is configured to receive the passed light signal from the light sensor and to return at least a portion of the light from the passed light signal back to the light sensor.
    Type: Grant

  • Control of thermal energy in optical devices
    Patent number: 9759982
    Abstract: The optical device includes an optical modulator positioned on a base. The modulator includes a ridge extending upward from the base. The ridge includes an electro-absorption medium through which light signals are guided. A thermal conductor is positioned so as to conduct thermal energy away from the ridge. The distance between the thermal conductor and the ridge changes along a length of at least a portion of the ridge.
