Wiener Filter for Short-Reach Fiber-Optic Links

Noise in Fiber Optic Communication Links

The physics of noise in optical communication links is of great interest in the design of fiber optic communication systems. In this report the role of noise in optical communications, and how it can limit the performance of optical communications systems, will be examined. The origins of noise in the various optical and analog electronic components will be discussed, and a methodology for a “n...

Continuous Phase Modulation for High Speed Fiber-optic Links

Adaptive CMOS Predistortion Linearizer for Fiber-Optic Links

Nonlinearity in the electrical-to-optical conversion limits the dynamic range for transmitting analog and multilevel signals over fiber-optic channels. We describe a complementary metal–oxide–semiconductor (CMOS) predistortion linearizer that extends the dynamic range of both direct and externally modulated links. The linearizer achieves 13–24-dB suppression for both secondand third-order disto...

A fiber optic sensor for measuring glucose in aqueous solutions

In this paper, the set-up of a multi-mode fiber optic sensor for measuring glucose in aqueous solutions is investigated and evaluated. The basis of this sensor is based on the Fresnel Reflection. In this setup, a helium-neon laser is used as a light source, a fiber optic probe, photocell as detector and a digital multimeter. The statistical analysis of the recorded data shows a highly linear be...
