Internal photos of Laser Synthesizer instrument: left - top view of optical circuitry including Erbium Doped Fiber Amplifier and custom Fiber Bragg Grating filter assembly; right - bottom view of RF power amplifier, Mach-Zehnder modulator, DC power supplies (x3), and monitor & control. Developed at the SMA project office by Derek Kubo and Ranjani Srinivasan in collaboration with NAOJ, this instrument was designed to provide a pure optical local oscillator reference for distribution over long distances of optical fiber (Kubo et al. Aug 2013, IEEE T Microw Theory: 61(8), 3005-3014).
