Abstract :
We report the results of the output characteristics of a circular ring laser diode with two Y-junction output couplers which forms a hybridization of a circular ring resonator and a linear U shape resonator. It shows that the ring laser has two emission characteristic spectrums, a single mode emission at 652.86nm and a multi-modes emission at around 652.24nm by injection current of 70mA. Results of light-injection current measurements are presented to reveal the mechanism of modes hopping of laser outputs due to interaction between these two resonators. It shows that this novel circular ring laser diode provides an alternative approach for optical signal modulation and its potential applications in multi-wavelength optical communication system.
