To make sure high-performance optical systems don’t crack under pressure, selecting the right material is not a secondary consideration, it is foundational. The substrate used for an optical window or mirror governs the system’s optical performance, thermal stability, and resilience under operational conditions. Zygo™, a global leader in precision optics, distinguishes itself through a material-agnostic capability, manufacturing from an exceptionally...

Thin coatings consisting of materials such as gold or platinum that were applied via sputter coating do not always have the “metallic appearance” we are familiar with in everyday life. Gold or platinum coatings with layer thicknesses below 15 to 20 nm do not have the “gold appearance” or “platinum appearance” that one would expect. This is often interpreted by...

Outline of Optical amplifier measurementWith the increase in communication traffic, the importance of optical amplifiers such as EDFAs (erbium-doped fiber amplifiers) that can directly amplify optical signals without converting them into electrical signals has been widely deployed in traditional backbone optical transmission networks. This proven amplification technique has expanded to a next generation application to boost free space communication laser...

Overview of Pulsed Light Measurement Why use pulsed light? A semiconductor laser emits light by a driving current. This drive current causes the semiconductor laser chip to generate heat, causing a shift in the output wavelength and potentially damaging the laser. To avoid such problems, pulse-driven light emission is widely used. Furthermore, high-power industrial lasers may require an energy accumulation...

Optical transceivers are one of the indispensable key devices for optical communications that interconvert optical and electrical signals. There are various types of optical transceivers: SFP, QSFP, 200GbE, 400GbE, and other network standards. In recent years, optical transceivers have become increasingly high-power to extend communication distance. To accomplish this, the laser in an optical transceiver must have a longer cavity length to achieve high power capability, which causes side mode wavelengths close to the main signal. This increases the need for high resolution/high dynamic range in SMSR  (Side Mode Suppression Ratio) measurements. The AQ6380, which offers high resolution and wide dynamic range, is the perfect solution for SMSR measurements of  O-band lasers for 400GbE QSFP-DD optical transceivers. Reasons why engineers choose the AQ6380 monochromator OSA: 5 pm...

Modern materials analysis demands sample preparation tools that can keep up with the size, complexity, and sensitivity of engineering materials used in aerospace, semiconductors, and lithium-ion...

Oscilloscopes are essential tools for engineers, technicians, and researchers working with electronic signals. Choosing the right oscilloscope and understanding its technical specifications can significantly impact measurement accuracy and efficiency. This FAQ addresses some of the most important aspects of oscilloscope performance and application. General QuestionsWhat is an oscilloscope?An oscilloscope is an electronic test instrument used for observing the precise shape...

Plan view TEM specimens from a fully fabricated spin-transfer torque magnetic random-access memory (STT-MRAM) device were prepared using a Ga FIB system. Post-FIB concentrated Ar ion beam milling using the Model 1080 PicoMill® TEM specimen preparation system of these plan view TEM specimens allowed controlled thinning and produced artifact-free TEM specimens. FIB plan view specimen preparation followed by concentrated Ar...
