- Abstract
High‐power and high‐linearity photodiodes (PDs) are of critical importance to achieve high‐efficiency analogue fibre links. A small‐signal analysis is utilised on the nonlinear responsivity of the modified uni‐travelling‐carrier PDs to understand the theoretical limitation on the third‐order output intercept point (OIP3) of the link. It is theoretically shown that a nonlinear responsivity depending on both the voltage and the current can give rise to an enhanced OIP3 at certain bias and current values.
