Hybrid silicon evanescent devices
The indirect bandgap of Si has been a key hurdle in the achievement of optical gain elements. Raman lasers and amplifiers1-3 have been demonstrated, and optical gain in nanopatterned Si4 has also been observed, but an electrically pumped all-Si gain element has yet to be realized. An alternative to creating an electrically pumped all-Si gain mechanism is to take prefabricated lasers and couple ...
متن کاملEvanescent Wave Illumination
When an electromagnetic wave (light) in a dielectric medium of index n1 is incident upon an interface of a different dielectric material of a lower optical density, n2 at an angle θ1 greater than the critical angle, θc = sin−1(n2/n1), total internal reflection (TIR) occurs. Although all of the incident energy is reflected, an electromagnetic field with exponentially decreasing intensity propaga...
متن کاملUnderwater Noise Modelling of Wave Energy Devices
Future large-scale implementation of wave energy converts (WECs) will introduce an anthropogenic activity in the ocean which may contribute to underwater noise. The Ocean houses several marine species with acoustic sensibility; consequently the potential impact of the underwater noise needs to be addressed. At present, there are no acoustic impact studies based on acquired data. The WEAM projec...
متن کاملJohnson Noise and Shot Noise
Two types of electrical noise fundamental to any circuit and their relation to fundamental constants are investigated. Johnson noise of a controlled-gain system is measured across different resistances and temperatures, leading to a calculation of the Boltzmann constant k = (1.48± .07)×10−23J/K and absolute zero T0 = −(270±30) ◦C. The shot noise of a variable-current system is measured, leading...
متن کاملEvanescent wave transport and shot noise in graphene: ballistic regime and effect of disorder
We have investigated electrical transport and shot noise in graphene field effect devices. In large width over length ratio W/L graphene strips, we have measured shot noise at low frequency (f = 600–850 MHz) in the temperature range of 4.2–30 K. We observe a minimum conductivity of 4e 2 πh and a finite and gate dependent Fano factor reaching the universal value of 1/3 at the Dirac point, i.e. w...
