*3 10µW,

φ30µm of DC light is applied to the center of each photodiode.

Under that condition, sensitivity R is shown by following formula.

*4 Light source : laser diode of

λ=780nm

*6 Frequency sensitivity is -3dB.(reference sensitivity : value at f= 1 MHz)

*5 Extreme of sensitivity is shown by following formula.

*7 In addition to 10µW,

φ30µm DC light, 4µWp-p AC light is applied to the center of each photodiode. BW=10kHz
