Enhancing the Vertical Resolution of Coherent Optical Receivers

The constantly increasing capacity demand in optical fiber transmission systems has driven the development of higher-order modulation to share the cost and power-consumption of optoelectronic

STATE-of-the-art

We explore a solution to improve the performance of optical coherent transceivers using optical intensity reshaping to improve the overall vertical resolution. We will be focusing only on the coherent receiver

Optical Receivers: Structures, Performance, and Optimization

Optical Receiver Performance Measures Before comparing different optical receiver concepts and discussing the most relevant receiver design trade-offs, we introduce some important receiver

The fastest receiver is the p-n photo diode, which can be very fast due to drift. The most sensitive receiver is the avalanche photo diode (APD), where the sensitivity is achieved by the

Enhancing the Vertical Resolution of Coherent Optical Receivers

Finally, we show that the proposed technique to increase the effective resolution will also boost the performance of digital backpropagation used to mitigate fiber Kerr nonlinear response.

Optimal Imaging Receiver Design for High-Speed Mobile Optical

The optical receivers suitable for the next generation of optical wireless networks need to be ultra-high-speed while having a wide field of view (FOV) to accommodate user mobility. The design of such

Summary

This chapter introduces the basic concepts related to such photodetectors and discusses several types of photodetectors used for optical receivers. It also introduces basic concepts such as

Optical Receiver

An ''Optical Receiver'' is a device that detects and converts the light received from a transmitter into an electrical signal. It consists of a photodetector and an amplifier, which work together to minimize

Optical resolution

Optical resolution is the resolved detail of an imaging system by scale. An imaging system may have many individual components, including one or more lenses, and/or recording and display components.

Receiver Performance

Receiver sensitivity and power margin have been widely used to specify the performance of optical receivers and optical transmission systems. In a traditional optical system without inline optical

The purpose of a receiver in an electronic communication system is to extract the information sent by the corresponding transmitter with as minimum a carrier power level as possible. The primary function of

Frequency response metrology for high-speed optical receivers

Abstract: We use “standard” optical sources along with microwave calibration methods to accurately calibrate optical receivers to 50 GHz and beyond. The calibrated receivers can be used to

Optical Receiver Operation | Springer Nature Link

The design of an optical receiver can be quite sophisticated because the receiver must be able to detect weak, distorted signals and make decisions on what type of data was sent based on

Optical Receiver Design | Springer Nature Link

In this chapter we consider issues related to the design of optical receivers. As signals travel in a fiber, they are attenuated and distorted, and it is the function of the receiver circuit at the
