It is known that PN-type photodiodes possess high optoelectronic chromatic dispersion (OED). Here we present a theoretical and experimental study of OED in PIN-type photodiodes. Applying the modulation phase-shift technique, Ge PIN photodiode exhibits ∼0.5 deg/nm sensitivity at 10 MHz modulation, corresponding to 1.4 ×10
