Synopsys, Inc. (Mountain View, CA) offers enhancements to its CODE V® optical design and analysis software, acquired as part of Synopsys' acquisition of Optical Research Associates. CODE V 10.4 delivers enhancements to its Beam Synthesis Propagation (BSP) tool that enable optical designers to model and analyze diffraction effects in an optical system with increased flexibility, speed and accuracy. These enhancements are particularly useful for evaluating the performance of optical designs with stringent accuracy requirements, such as microlithography lenses, laser scanning systems, and optical telecommunication devices. BSP uses a unique, beamlet-based algorithm to produce a physically accurate model of the wave nature of light as it travels through an optical system. It accounts for aberrations and diffraction effects (interference), including the impact of aperture clipping and apodizing filters. BSP enables designers to have a full understanding of how diffraction impacts key system performance measures by providing high-accuracy computations of the optical beam intensity, amplitude and phase characteristics. Another unique capability of BSP is its pre-analysis feature, which recommends analysis parameters customized for the user's lens system, helping to minimize analysis setup time and deliver the answers designers need for system validation.
CODE V 10.4 adds support for general complex field input to BSP. This gives users flexibility to customize the input beam (light source) description by providing detailed maps of the beam's intensity and phase. For example, complex optical field data can be imported from external software programs that model waveguides for photonic devices. This feature also allows the definition and propagation of higher-order laser modes.
