This paper presents the fabrication process of single-crystalline diamond platform used for high power RF components. We report-for the first time to the best of our knowledge-results of a Coplanar Waveguide (CPW) transmission line printed on the single-crystalline diamond substrate using the Aerosol Jet Printing technique. The transmission line is 2.44 mm long and is printed on the 3.5 mm × 3.5 mm...
We present a new, coupled-mode formalism based, Analytical approximation for photonic array modes in 2D electro-optical components, based on photonic crystal lattices (arrays of identical coupled waveguides / lasers) and superlattices (periodic sequences of different coupled waveguides / lasers). The two most popular configurations (square and hexagonal lattices and superlattices) are considered....
We present a new approach for analysis of optical properties of holey photonic crystal devices. Our approach is based on the Extended coupled-mode formalism, developed for analysis of infinite photonic crystal lattices (arrays of identical coupled waveguides / lasers) and superlattices (periodic sequences of different coupled waveguides / lasers). Our method allows for a fast (tens of seconds) calculation...
Moral identity is a construct at the intersection of moral development and identity formation. It is thought to be a source of moral motivation linking moral reasoning (our judgments about whether certain actions are right or wrong) to behavior. In other words, people with a stronger sense of moral identity will be more likely to do what they know is right, and more likely to show enduring moral commitments...
The attack of a severe tropical cyclone at any location is a rare event; therefore, a long data record is necessary in order to determine the characteristics of the population of storms that can affect a location. Unfortunately, reliable and complete data of tropical cyclone tracks and central pressures are not nearly long enough to define the severe end of the distributions. To mitigate this problem...

A new, coupled-mode formalism based, analytical approximation for array modes in perfectly-periodic 1D photonic devices (photonic crystal lattices and superlattices) is presented. We consider the specific class of 1D photonic crystals (encompassing large arrays of coupled planar waveguides, phase-locked lasers etc.), in which light propagates along the optical axis of the device. Approximate analytical...
Coupled Mode Theory (CMT) is a well-established formalism, which is widely used in the computation of the optical characteristics of photonic devices, matching the model of array of parallel waveguides [1]-[6]. In particular, it is applicable to 2D photonic crystal devices (i.e. arrays of coupled waveguides / phased laser arrays), in which light propagates along the optical axis of the component....
One of the main benefits of the smart grid will be the introduction of Distributed Energy Resources (DERs) into the electricity grid at large scale. These DERs will be able to supply areas with electricity when isolated from the main power grid due to failure conditions or system/equipment failures. Although the integration of DER into the power grid makes the energy supply more reliable and reduces...
Presented are here new, approximate, methods for the calculation of photonic supermodes in 1D photonic devices (arrays of coupled planar waveguides, phase-locked arrays of lasers etc.), in which light propagates mainly along the optical axis of the array. These methods propose a simple, fast and quite accurate way for the estimation and prediction of the spatial distribution of the EM field in 1D...
Coupled Mode Theory (CMT) is a well-established formalism widely used in the analysis of propagation and interaction of electromagnetic modes in arrays of parallel waveguides, coupled resonator optical waveguides (CROWs), phase-locked arrays of VCSELs etc. So far, CMT analysis considered only situations where both the dielectric function and the input optical signal were assumed to be time-independent...
Gain switching of unidirectional erbium-doped waveguide ring lasers is studied using numerical simulations based on the time-dependent rate-propagation equations. The counter-directional wave suppression is analyzed for different waveguide ring cavity configurations and pumping schemes. It is shown that for the one-end pumped gain-switched erbium-doped waveguide ring laser, highly unidirectional operation...
In an emergency situation failure to respond in a timely manner poses a significant threat. Data needed for timely response comes from various sources and sensors. These individual data streams when viewed in isolation may appear irrelevant, however, when analyzed collectively may identify potential threats. An effective and timely response also requires collaboration and information sharing among...
Pulse propagation in Er3+-doped fiber amplifiers (EDFA) is studied within the framework of a spectrally-resolved pulse rate-propagation equations model. Calculated pulse spectrograms demonstrate the effects of dispersion on sub-picosecond pulse propagation in EDFAs.
Summary form only given. The /spl alpha/-DFB laser design contains an embedded diffraction grating that is angled with respect to the laser facets and a contact stripe aligned parallel to the grating teeth that extends the length of the cavity. The epitaxial structure is otherwise similar to that of a conventional DFB laser diode. The gratings provide lateral optical confinement by virtue of multiple...
