Abstract
Precise optical wavelength measurements can be performed by use of a novel wavelength sensor. This low-cost sensor consists of a wavelength-sensitive photodiode and a high-precision log ratio amplifier. The center wavelength of monochromatic or narrowband light sources such as semiconductor lasers in the visible or near-infrared wavelength range can be determined. By simultaneously testing the properties of monomode laser diodes with a standard wavemeter, the feasibility and precision of the wavelength sensor are demonstrated. Wavelength variations less than 0.1 nm are detected clearly.
