Abstract :
Radial uniformity in the transmission characteristics of a circularly tunable optical disk filter allows temperature-insensitive wavelength discrimination. The temporal traces of transmitted powers for a laser wavelength measured in synchro-scan mode over the 13.5-73.5°C range exhibited a small temperature dependence of 3 pm/°C coming only from the thermal expansion of the filter layers
