摘要： A multi-junction opto-electronic device including a stack of wavelength selective absorption layers is proposed. The absorption layers include each a first layer with a grating of a specific pitch defining the wavelength of the incident light to be absorbed within a subjacent second electrically active layer itself on a third electrically inactive layer. The second electrically active layer within the different absorption layers is in electrical connection with lateral contacts to extract the electrical charge carriers generated by the absorbed incident light within the active layer. The grating within the first layer of the absorption layers is defined by periodic stripes of specific width depending on the wavelength to be absorbed by the respective absorption layers. The period of the stripes alignment is defined by the pitch of the grating. Advantageously, ordinary silicon technology can be used.

摘要： A clock data recovery system is provided for resampling a clock signal according to an incoming data signal stream. It comprises a clock generator for generating said clock signal wherein one of the frequency and phase of that clock signal is dependent upon a control signal. It is further provided a phase detector operable to detect the phase difference between said clock signal and said incoming data signal stream and is operable to generate a phase difference signal. A loop controller has a variable-gain and is operable to control said clock generator by generating said control signal. That control signal is dependent in said phase difference signal and that variable-gain. The variable-gain is dependent upon a transition rate of the incoming data signal stream. The loop controller can comprise a low-pass filter to generate from the phase difference signal a low-pass filered phase signal and to adjust the bandwidth of the clock data recovery system. The loop controller further can comprise a variable-gain element to amplify the filtered signal in accordance with a received bit transition rate provided by a bit transition detector and a density calculator.
