Low-complexity two-stage equalizer for receiver IQ imbalance
In this paper, we propose a low-complexity two-stage equalizer that can be used in real-time systems. The performance of the proposed equalizer was verified through a 112 Gbit/s
In the optical domain, an equalizer is a device that equalizes the gain response over a particular wavelength range. The main reason for this equalization is to enable the cascading of amplifiers. Equ...

An optical receiver usually consists of a photodetector and an electrical circuit for transimpedance amplification and signal manipulation. Important parameters of an optical receiver include
This work aims to solve this discrepancy by presenting an accurate analysis for CTLE-based optical receivers considering noise, gain, and jitter.
Equalization is the process of applying a filter (the "equalizer") at the receiver to undo the distortions introduced by the channel. The goal is to restore the transmitted signal to its original shape as
In a high-speed, long-haul, fiber-optic communication system, fiber dispersion can cause serious performance degradations. Here, we describe an optical equalizer consisting of a reflective cavity
The design of an optical receiver depends on the modulation format used by the transmitter. Since most lightwave systems employ the binary intensity

The adaptive optical LMS-FIR equalizer system is illustrated in Fig. 1. A data-carrying signal is transmitted along with a pilot tone; after de-multiplexing, the signal is processed by an optical filter
The equalizer in an optical receiver normally is a linear frequency-shaping filter used to mitigate the effects of signal distortion and intersymbol interference.
A high-sensitivity, low-power receiver is a critical component, determining the overall optical power budget of a short reach optical interconnect system.
A typical optical receiver is shown in Figure . The three basic stages of the receiver are a photodetector, an amplifier, and an equalizer.
