From: Waveguide coupled III-V photodiodes monolithically integrated on Si
a Linearity at 1 GHz measured on device T2 at different reverse bias voltages, showing output power (Pout) vs input power (Pin). b Linearity at a constant 1.5 V reverse bias measured on device T2 for different small-signal frequencies. c Radio frequency (RF) signal response dependence on modulation frequency of the input signal measured on device T3. d 50 GBd OOK eye diagram measured on device T3. e 50 GBd 4PAM eye diagram measured on T3.
