3D Vectorial Time Domain Computational Integrated Photonics
Abstract
The design of integrated photonic structures poses considerable challenges. 3DTimeDomain design tools are fundamental in enabling technologies such as alloptical logic, photonic bandgap sensors, THz imaging, and fast radiation diagnostics. Such technologies are essential to LLNL and WFO sponsors for a broad range of applications: encryption for communications and surveillance sensors (NSA, NAI and IDIV/PAT); high density optical interconnects for highperformance computing (ASCI); highbandwidth instrumentation for NIF diagnostics; microsensor development for weapon miniaturization within the Stockpile Stewardship and DNT programs; and applications within HSO for CBNP detection devices. While there exist a number of photonics simulation tools on the market, they primarily model devices of interest to the communications industry. We saw the need to extend our previous software to match the Laboratory's unique emerging needs. These include modeling novel material effects (such as those of radiation induced carrier concentrations on refractive index) and device configurations (RadTracker bulk optics with radiation induced details, Optical Logic edge emitting lasers with lateral optical inputs). In addition we foresaw significant advantages to expanding our own internal simulation codes: parallel supercomputing could be incorporated from the start, and the simulation source code would be accessible for modification and extension. This work addressed Engineering's Simulationmore »

This work addressed Engineering's Simulation Technology Focus Area, specifically photonics. Problems addressed from the Engineering roadmap of the time included modeling the Auston switch (an important THz source/receiver), modeling Vertical Cavity Surface Emitting Lasers (VCSELs, which had been envisioned as part of fast radiation sensors), and multiscale modeling of optical systems (for a variety of applications). We proposed to develop novel techniques to numerically solve the 3D multiscale propagation problem for both the microchip laser logic devices as well as devices characterized by electromagnetic (EM) propagation in nonlinear materials with timevarying parameters. The deliverables for this project were extended versions of the laser logic device code Quench2D and the EM propagation code EMsolve with new modules containing the novel solutions incorporated by taking advantage of the existing software interface and structured computational modules. Our approach was multifaceted since no single methodology can always satisfy the tradeoff between model runtime and accuracy requirements. We divided the problems to be solved into two main categories: those that required Full Wave Methods and those that could be modeled using Approximate Methods. Full Wave techniques are useful in situations where Maxwell's equations are not separable (or the problem is small in space and time), while approximate techniques can treat many of the remaining cases.},

TEMPESTN33.5 provides numerical solutions to general incompressible flow problems with coupled heat transfer in fluids and solids. Turbulence is created with a ke model and gas, liquid or solid constituents may be included with the bulk flow. Problems may be modeled in Cartesian or cylindrical coordinates. Limitations include incompressible flow, Boussinesq approximation, and passive constituents. No direct steady state solution is available; steady state is obtained as the limit of a transient.

Simulation of planar integrated photonics devices with the LLNL time domain finitedifference code suite
Interest has recently grown in applying microwave modeling techniques to optical circuit modeling. One of the simplest, yet most powerful, microwave simulation techniques is the finitedifference timedomain algorithm (FDTD). In this technique, the differential form of the timedomain Maxwell's equations are discretized and all derivatives are approximated as differences. Minor algebraic manipulations on the resulting equations produces a set of update equations that produce fields at a given time step from fields at the previous time step. The FDTD algorithm, then, is quite simple. Source fields are launched into the discrete grid by some means. The FDTD equations advance thesemore » 
Integrated system for production of neutronics and photonics calculational constants. Volume 15, Part D, Rev. 1. The LLL Evaluated Nuclear Data Library (ENDL): descriptions of individual evaluations for Z = 098
Descriptions of evaluated nuclear data sets for 86 isotopes in the range Z = 0 to 98 are presented. The evaluation procedures that were used are discussed. At the beginning of the discussion for each individual isotope, a computergenerated listing is given which summarizes the main properties of the data sets that are contained in the evaluation.

The computer code LINEAR converts evaluated cross sections in the ENDF/B format into a form that can be defined by applying linearlinear interpolation to energy and cross section parameters. The code also thins those sections already in that form. The main advantage of the code is that it eliminates the need for any subsequent code to consider anything but linearlinear data. 2 figures.

The code SIGMA1 Doppler broadens evaluated cross sections in the ENDF/B format. The code can be applied only to data that vary as a linear function of energy and cross section between tabulated points. This report describes the methods used in the code and serves as a user's guide to the code. 6 figures, 2 tables.
