Abstract

We report on an integrated approach to obtain two color emission from a semiconductor
ring laser with filtered optical feedback. This feedback is realized on-chip by employing
two arrayed waveguide gratings to split/recombine light into different wavelength channels.
Semiconductor optical amplifiers are used in the feedback loop to control the feedback
strength of each wavelength channel independently. Results show that the effective
gain of the different modes is the key parameter which has to be balanced to obtain two
color emission. This can be achieved by tuning the injection current in each amplifier.
