These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookSilicon Photonics: Light Is the Ultimate Medium for High-Speed Communications: Thanks to innovations with heterogeneous material integration and multiphotonic layer stacking, silicon photonics will drive optical solutions to high volumes and low costs.Silicon photonics is widely considered a key enabling technology for further development of optical interconnect solutions needed to address growing traffic on the internet. From the first submarine...Photonics HandbookPhotomultipliers: Low-Light, High-Speed Specialists: Rapid detection of light calls for a sensitive detector and electronics that do not introduce additional signal noise. In fact, for very rapid detection, detector shot noise does not determine the signal-to-noise ratio. Instead, the amplifier has the most impact, which is why many designers have selected a photomultiplier tube for the high-speed or low-light-level detection of photons.The applications where rapid detection of light is a must are many. They include a wide variety: semiconductor inspection, gene sequencing, oil well logging and high-energy physics. The reasons for...Photonics HandbookInfrared Spectral Selection: It Begins with the Detector: An IR imaging system employing a narrow spectral band brings hidden images to light, broadening IR imaging’s applications.Spectral selection is a powerful tool that enhances conventional imaging tremendously.
