What is the linearity of an optical receiver
Linearity refers to the proportional relationship between the input optical signal and the output electrical signal. When an optical receiver exhibits high linearity, it can accurately reproduce the amplitude and phase of the incoming signals across a wide dynamic range. One of the key factors influencing this performance is the linearity of the receiver's response. This thesis presents a highly linear, power-efficient main amplifier for PAM-4 and NRZ optical receivers, implemented in 65-nm CMOS.

What does an amplitude-modulated optical receiver do
This process dynamically alters properties of an optical carrier wave—such as amplitude, phase, frequency, or polarization—to embed data. Its inverse, demodulation, extracts this information at the receiving end. An audio signal (top) carried by a carrier signal using amplitude modulation (middle) and frequency modulation (bottom) Amplitude modulation (AM) is a signal modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. It is mainly used in radio broadcasting, aviation communication, and various signal transmission applications. This modification is performed according to a specific scheme that is implemented by the transmitter and understood by the receiver.
