    Abstract: Some embodiments include apparatus and methods having an input to receive an input signal, additional inputs to receive clock signals having different phases to sample the input signal, and a decision feedback equalizer (DFE) having DFE slices. The DFE slices include a number of data comparators to provide data information based on the sampling of the input signal, and a number of phase error comparators to provide phase error information associated with the sampling of the input signal. The number of phase error comparators of the DFE slices is not greater than the number of data comparators of the DFE slices.

    Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for a photonic apparatus with a photodetector with bias control to provide substantially constant responsivity. The apparatus includes a first photodetector, to receive an optical input and provide a corresponding electrical output; a second photodetector coupled with the first photodetector, wherein the second photodetector is free from receipt of the optical input; and circuitry coupled with the first and second photodetectors, to generate a bias voltage, based at least in part on a dark current generated by the second photodetector in an absence of the optical input, and provide the generated bias voltage to the first photodetector. The first photodetector is to provide a substantially constant ratio of the electrical output to optical input in response to the provision of the generated bias voltage. Additional embodiments may be described and claimed.
