Vertical photodetector example current calculation

    • Mariah Ha


      In the vertical photodetector lumerical example , when extracting the current from the cathode side, it is multiplied by a factor of 2 . Can anyone explain this please? Normally the total current in the cathode should be extracted without further multiplication if it refers to the total current , right ?

      Hello Here only half of the device is simulated to reduce simulation time (the device is symmetric):
      In the calculations the current is multiplied by two to account for this configuration. A similar scaling is done for the steady-state simulation in "vpd_CHARGE_steady_state.lsf".
      Best regards
