The 15th Annual Meeting of the IEEE Lasers and Electro-Optics Society.
The possibility of wavelength tuning and insertion of intra-cavity control elements makes vertical external cavity surface emitting lasers (VECSEL) a useful tool for telecommunication and spectroscopic applications. Very small cavity lengths are desi

The interaction between a surface acoustic wave (SAW) and photogenerated charge carriers in a piezoelectric semiconductor substrate leads to pronounced changes in the transmission properties of the SAW. Depending on the charge carrier density one obs

We study both theoretically and experimentally the interaction of intense surface acoustic waves with an electron and an electron-hole plasma of a quantum well. The experiments performed on hybrid semiconductor-piezocrystal structures exhibit strong

A new method to optically examine surface acoustic wave (SAW) propagation on a semiconductor chip is presented. This visualization method is based on the influence of a SAW on the optical properties of a piezoelectric semiconductor. There are two int

2000 IEEE Ultrasonics Symposium. Proceedings. An International Symposium (Cat. No.00CH37121).
Sophisticated high frequency signal processing as well as sensor applications based on surface acoustic waves (SAW) often require a complex transducer layout. We present a simple numerical technique based on a Huygens-type construction to calculate a

We study the plateaux of the integer quantum Hall resistance in a bilayer electron system in tilted magnetic fields. In a narrow range of tilt angles and at certain magnetic fields, the plateau level deviates appreciably from the quantized value with

We develop a quantum theory of the nonlinear interaction between intense surface acoustic waves and electrons in a quantum well in the regime of moving quantum wires and dots. In the quantum nonlinear regime, the sound attenuation exhibits quantum os

Nonlinear interaction of an intense surface acoustic wave (SAW) with a 2D electron-hole plasma generated by light in a semiconductor quantum well near a piezoelectric crystal is investigated. It is shown that, in a strongly nonlinear regime, the acou
