    Would a gallium arsenide photodiode be sensitive to light from a gallium phopsphide LED?

    Probably :
    You can make GaP LEDs in green->red
    GaAs photodiodes certainly work in the visible (used as solar cells) don't know their response curve and it's probably sensitive to the thickness and structure of the diode.
