Abstract :
The authors report simultaneous oscillation of 17 0.8 nm spliced wavelengths from a Fabry-Perot (FP) erbium doped fibre laser. Multiwavelength operation is made possible by inserting an intracavity etalon and cooling the erbium doped fibre at 77 K by liquid nitrogen. It is promising as the multiwavelength light source for wavelength division multiplexing (WDM) networks. Heterodyne measurement shows that two or three longitudinal modes exist in each wavelength
