Design of Hybrid Silicon Evanescent Amplifiers

The structure and design of a hybrid silicon evanescent amplifier, incorporating III-V offset quantum wells bonded on a silicon waveguide, is proposed and discussed.

A hybrid AlGaInAs-silicon evanescent waveguide photodetector.

We report a waveguide photodetector utilizing a hybrid waveguide structure consisting of AlGaInAs quantum wells bonded to a silicon waveguide. The light in the hybrid waveguide is absorbed by the AlGaInAs quantum wells under reverse bias. The photodetector has a fiber coupled responsivity of 0.31 A/W with an internal quantum efficiency of 90 % over the 1.5 mum wavelength range. This photodetect...

Using electronic coherence to probe a deeply embedded quantum well in bimetallic Pb/Ag films on Si(111).

We report an experiment in which we utilize electronic coherence to probe a deeply embedded thin film as a quantum well. An atomically uniform Ag film prepared on Si(111) was covered by Pb films up to 70 A thick, and the resulting electronic structure was examined by angle-resolved photoemission spectroscopy. Despite a photoemission escape depth of just a few Angströms and an incommensurate Pb/...

Coherent resonant transmission in temporally periodically driven potential wells: the Fano mirror

The electron transmission over an oscillating quantum well is studied perturbatively and numerically in the phase-coherent regime. The dynamically induced multichannel situation gives rise to a pronounced asymmetric resonance and antiresonance structure. The Fano line obtained is attributed to the interaction of the raised virtual discrete energy level with the continuum. Interestingly, the uni...
