Abstract :
Dynamic single-frequency operation of a laterally coupled waveguide (LCW) laser modulated at 1 GHz is reported for the first time. The device consists of three optically coupled but electrically separated resonators arranged side by side. By using two of the three coupled lasers as stabilising sources a resolution limited chirp of 0.022 nm has been achieved at a modulation depth of 85%.
