Probing electrical signals in silicon CMOS devices using electric field induced second harmonic generation

We report the use of electric field induced second harmonic generation to probe electrical signals in a CMOS chip. The second harmonic of incident 2.3 m illumination provided by a femtosecond optical parametric oscillator was measured and shown to .depend quadratically on both optical intensity and on the applied DC electric field. By using a near infrared photomultiplier tube it was possible to monitor directly the electrical waveform in the chip on the oscilloscope

Possibilities and limitations of data communication over large core diameter PMMA POF

Large core diameter PMMA POF is reliable and easy to handle and terminate. But unlike glass optical fiber or perfluorinated POF both a visible light source and a large area detector are necessary to achieve its benefits. Most current applications for PMMA POF like Ethernet media converters and the MOST bus work at data rates of up to 100 Mbit/s. State-of-the-art components with data rates up to 500 Mbit/s are commercially available. In this paper we will discuss the limits of optoelectronic devices on transmitter and receiver side. This includes devices like LEDs, side emitting LASERs, different photodiodes and concepts of the necessary driving circuitry. We will also take a close look at high-speed devices, like red VCSELs. Finally we will discuss, that even 10 Gbit/s over POF with a core diameter of 500 µm or larger should be feasible
