【Technical articles】RSoft Application: Graphene-Based Electro-Optic Nano-Modulator


A leading electro-optical company in Japan needed to design a graphene-based modulator. Graphene, which has a high modulation efficiency, is a promising material choice for nanoscale modulators.


【Technical articles】RSoft Application: Arrayed Waveguide Grating (AWG)


IMEC, a leading European research and foundry organization, needed to extend silica AWG multiplexing technology to a silicon-based, on-chip platform.


【Technical articles】OptSim Circuit: Simulation of AIM Photonics Transmitter-Receiver and Generation of Masks


The time for large-scale, reliable photonic integrated circuits (PICs) has finally arrived. In addition to the favorable economics from higher energy efficiency, smaller footprint and lower cost, photonic integration is recognized as essential to national security. The role of photonic design automation (PDA) tools, including OptSim Circuit [1], is going to be as indispensable to PICs as was (and still is) the role of electronic design automation (EDA) tools to the fruition of Moore’s law for CMOS over the last 50 years.

【Technical articles】Creating Custom PDK Models with the S-Matrix/Custom PDK Generation Utility


Although photonic foundries continue to enhance support for wider arrays of active and passive photonic PDKs based on different technologies, there are times when the ability to generate custom & proprietary PDKs and to use them in circuit simulations and mask generation are important. Whether the motive is to generate intellectual property (IP), or to supplement an existing PDK, OptSim Circuit together with RSoft’s device modeling tools offer virtually limitless ways to create custom components and PDKs and deploy them in PICs.

【Technical articles】Color Design and Analysis in LightTools


LightTools® has a comprehensive suite of tools for accurately and efficiently simulating chromatic effects in an optical system. Additionally, LightTools allows you to optimize your system using color metrics in your merit function to achieve the best possible chromatic performance. You can fine tune your simulations, sources, and receivers to maximize efficiency, minimize statistical noise, and get the most out of your design time. LightTools includes a full range of analysis and charting options, as well as a powerful photorealistic rendering capability that can accurately depict lit sources in your model.
In the following sections, some of LightTools’ many color features are discussed in more detail.
