Optical Signal Processing
<Note> This article is still updating. Check back soon for more update.
According to Fraunhofer HHI :
Optical signal processing refers to a broad range of techniques that operate in optical data signals. In particular all-optical signal processing uses nonlinear effects in optical media for optical data manipulation. The advantages are higher bandwidth, faster processing speed, no need for opto-electrical / electro-optical conversion.
Examples of functions that can be performed with nonlinear devices are :
- Wavelength conversion
- Optical multiplexing and demultiplexing
- Fast / discrete Fourier transform
- Digital-to-analog (D/A), and analog-to-digital (A/D) conversions
- Optical logic gates (AND, OR, XOR, etc.)
- All-optical tunable delays
