Fig. 1: Overview of key functionalities enabled by optical wave energy redistribution (OWER) techniques.
From: Linear optical wave energy redistribution methods for photonic signal processing
The fundamental basis of these functionalities are the two linear OWER techniques known as spectral phase filtering (SPF) and temporal phase modulation (TPM). Both simply rearrange the energy of an input optical wave to perform a desired mathematical transformation directly in the analogue optical domain. Chapter 3 deals with real-time spectrum analysis and processing functionalities. Chapter 4 treats on-the-fly high-speed waveform processing as well as lossless control of optical pulses and combs. Chapter 5 discusses other functionalities including optical logic and optical neural networks. Chapter 6 discusses extensions to and techniques unique to the quantum domain. Chapter 7 discusses how TPM and SPF at the heart of OWER methods can be implemented on chip.
