Abstract

Recent improvements in GaAlAs lasers have made them potentially useful in many new applications. The ability of the lasers to be directly modulated at gigahertz rates, combined with their high efficiency and small size, make them logical candidates for use in many communication and instrumentation systems. However, those applications that are sensitive to emission wavelength, such as heterodyne spectroscopy, FM communication, or wavelength-multiplexed fiber-optic communication, require detailed knowledge of wavelength tuning in pulsed conditions.^1,2
