Solving 5 Big Thin-Film Deposition Challenges Facing Contract CoatersThe contract thin-film coating industry is poised for growth, with many target markets expected to see substantial gains over the next five to ten years. Contract coaters need to align their production platforms to take advantage of these lucrative opportunities. This paper dives into solutions for the five big thin-film deposition challenges that contract coaters are facing today - and how to help them better position themselves to realize their own growth.
Six Best Practices for Optical Product Design TeamsIn their groundbreaking study Six Myths of Product Development, Stefan Thomke and Donald Reinertsen exposed common fallacies of product development and presented best practices for overcoming them (Harvard Business Review, May 2012). This eGuide...
How to Fail Fast and Smart During the Optical Product Design ProcessFailure is an inevitable part of the product development process, because you have to explore all the ways a design won’t work to find the way it will work. When you’re in a situation that demands speedy development cycles, how can you fail faster...
Accelerating Photonic Simulations with the Effective Index Method in RSoft ToolsThe Effective Index Method (EIM) can be used in Synopsys RSoft™ photonic design software to greatly reduce the computation time and memory requirements of a simulation by converting a 3D structure into an approximate 2D structure. This is also...
Electrical-to-Optical and Optical-to-Electrical Converter MeasurementsAs fiber and free-space optical communication bandwidths increase, the need for very high speed optical modulators and detectors has also increased. The frequency response characterization of these electrical-to-optical (E/O, modulators sometimes...
Key Considerations when Designing and Implementing an Outdoor-ready Smart Imaging SystemThe key to a successful all-in-one imaging system is the use of embedded systems – especially when it comes to designing a custom proprietary system. This white paper walks you through key elements to consider when designing an embedded vision...
Working in the Basement: Measuring Signals Below the Noise Floor with a Lock-In AmplifierMeasuring optical signals in the femtowatt (10-15) to nanowatt (10-9) range can be a daunting task. Signal levels this low are lost in typical detector noise levels and swamped by background light. The noise floor for photodiode detectors operated...
High-Performance FDTD Simulations with Sub-Cell/Conformal Meshing in RSoft FullWAVEDue to the computationally intensive nature of the FDTD simulation method, improved accuracy and convergence are critical for its practical use as a design algorithm in applications where numerous design variants need to be explored. This white...
Designing and Selecting an Optical Cleaning ProcessEvery optical application requires a "clean" optical surface. However, what defines "clean" is subjective and is based on the needs of the application. In addition, there is not a singular low-cost cleaning process that can meet all the demands of...
Gas Purging Keeps UV Spectrophotometers HealthyMeasuring in the far-UV (FUV) 120-220 nm presents unique challenges. The high energy that makes UV light interesting can cause photochemical formation of organic films on optical surfaces. These films cause increasing, wavelength-dependent loss of...
Design Optimization of Grating Fiber Couplers with RSoft ProductsEngineers can readily achieve optimal design of silicon photonics devices using rigorous simulation tools to numerically optimize a large number of design parameters. This paper demonstrates how a complex grating coupler design can be efficiently...
Improving Focusing Quality of Spherical LensesEmploying aspherical lenses to reduce aberrations to improve focusing qualities is a well-known concept. But the potpourri of aspherical surfaces offers way more possibilities, even the chance for flexible beam shaping setups. Axicons are conical...
