Optical Spectrum Analyzer
An Optical Spectrum Analyzer (or OSA) is a precision instrument designed to measure and display the distribution of power of an optical source over a specified wavelength span. An optical analyzer spectrum trace displays power in the vertical scale and the wavelength in the horizontal scale.
The expanding field of optics-related applications has created a variety of industries and organizations that require advanced optical spectral measurements for both R&D and manufacturing. These industries include telecommunications, consumer electronics, healthcare, life science/medical research, security, sensing, microscopy, and gas/chemical analysis, and environmental monitoring.
Yokogawa (formerly Ando) is the global leader in optical spectrum analyzers, delivering high quality, cutting-edge technology with dependability, performance, and flexibility for over thirty years.

Lack of reliable high-speed internet access in rural regions, due to complicated logistics and the considerable costs involved to extend land-based networks to these areas, has inspired a wave of next-generation applications that will provide greater accessibility and reliability. Making use of “space laser” networks, these revolutionary solutions can relay digital traffic via low Earth orbit (LEO) satellite systems to provide low-latency, high-speed broadband services to communities typically beyond the reach of standard wireless and fiber networks.
To accurately measure pulsed light using an optical spectrum analyzer (OSA), it is necessary to understand the characteristics of the OSA and select the appropriate measurement method and settings.
We have developed the AQ6375 Optical Spectrum Analyzer grating-based desktop optical spectrum analyzer, which can measure an optical spectrum over a wide wavelength range from 1.2 to 2.4 m with high wavelength resolution at high speed. Despite the popularity of desktop optical spectrum analyzers in the telecommunication wavelength region, a large-scale optical spectrum measurement system with a monochromator has commonly been used for measuring the long wavelength region, and so there was a need for a desktop optical spectrum analyzer for long wavelengths. Deep optical absorptions appearing in the long wavelength region around 2 m caused by CO2, NOX and H2O are attracting attention in the environmental and medical fields, and thus sensitive measuring equipment by laser absorption spectroscopy using a near infrared semiconductor laser is becoming more popular. With excellent optical spectrum measurement capabilities (high resolution and high speed), operability and maintenance performance, the AQ6375 Optical Spectrum Analyzer optical spectrum analyzer will contribute to the performance improvement and spread of near-infrared semiconductor lasers used in laser absorption spectroscopy.
A new type of computer based on the theory of quantum mechanics, a quantum computer, is currently in development by researchers around the globe. The theory of quantum mechanics describes nature at the atomic and subatomic level. Quantum technology has the potential to build powerful tools that process information using the properties of atoms, photons, and electrons. These quantum computers could also address challenges of much greater complexity than what today's computers can solve, and help further advancements in science, technology, medicine, and more.
With countries spending billions of dollars, the race for who can produce the first practical, commercialized quantum computer is on. There are currently several approaches to build this sort of computer, and this all begins with creating and initializing quantum bits, also known as qubits.
This paper describes a compact optical channel monitor and a delayed interferometer having free-space optical elements such as lenses or mirrors, as an application of microoptics. These devices have been developed to be built into dense wavelength division multiplexing (DWDM) transmission systems. These optics use a Gaussian beam which is emitted through single-mode optical fibers and located near the optical axis. This paper explains the optical designs of these devices based on the Gaussian beam's behavior.
