Abstract
A multi-wavelength source incorporating a Semiconductor Optical Amplifer (SOA) and a Erbium-doped fiber amplifier
(EDFA) in a ring cavity configuration is demonstrated. The multi wavelength source is able to generate more than 12
channels at -35 dBm and above with a channel spacing of 0.8 nm at a SOA bias current of 350 mA and 980nm pump power
of 92 mW. The number of wavelengths generated can be controlled by adjusting the SOA bias current and the birefringence
of the ring cavity using the Polarization Controllers (PCs). The proposed laser has a channel spacing suitable for DWDM
and sensing applications and shows stable operation at room temperature.
