Abstract
A 4-channel frequency locking system has been demonstrated using a fibre-fed Fabry-Perot (FFP) filter with a free spectral range (FSR) of 100 GHz. A back-reflection curve from the FFP was used for the extraction of an error signal in such a way as to overcome the limitation in the number of accommodatable channels due to the saturation in a photodetector. The frequency stability and locking range of each channel were within 15 MHz and over 12 GHz, respectively
