We have studied the temporal behavior of atomic absorption signal under resonant excitation with a continuous-wave laser radiation. Measurements done for D2 line 85Rb ~ 1 ns resolution shown irregular oscillatory transmission signal, which becomes well pronounced high power, and disappears when is tuned off-resonance. Application fast Fourier transform analysis reveals power-dependent frequency...

Bragg reflection waveguides are shown to be structures that can enable the integration of a laser and optically nonlinear medium within the same cavity for efficient frequency conversion. An effective and simple method of designing phase-matched laser structures utilizing transfer matrix analysis is described. The structures are first optimized in terms of laser performance and then for enhance...

Piezoelectric transformers (PT) are an alternative to wire wound magnetic transformers because of numerous advantages i.e. being the electromechanical energy conversion, low EMI, a compact and low design, as well as a high potential of high efficiency and power density. The last two decades of research into piezoelectric transformer (PT) based power converters have led to some extensive improve...

Designing a low power clock network in synchronous circuits is an important task. This requirement is stricter for 3-D circuits due to the increased power densities. Resonant clock networks are considered efficient low-power alternatives to conventional clock distribution schemes. These networks utilize additional inductive circuits to reduce the power consumption while delivering a full swing ...

Thermophotovoltaic (TPV) systems offer a unique, solid-state approach to converting heat into electricity based on thermal radiation. TPV is particularly suitable for certain classes of power generation applications that are not well served by standard engines, such as long, remote missions where repairs are difficult, and portable generation where space and weight are at a premium. While stand...
