Abstract :
We presented the first integrated WDM ring laser. It operates CW at three adjacent wavelengths spaced by 3.2 nm. Lowest threshold currents are 70 mA and the SMSR is 30 dB when both the common and the selected SOA are operated at 100 mA.. One of the channels was not lasing because of a defect amplifier. The small size of the device (1.5 × 3 mm2) demonstrates the potential of compact technology.
