摘要：

We have fabricated a monolithic semiconductor ring laser with a diameter of 3.0 mm. A straight tangent waveguide provides two output ports through evanescent coupling. The laser, which exhibits a threshold current of 157 mA, operates in a single longitudinal mode with a linewidth of 900 kHz at a wavelength of 1.54-mu-m. The device has been actively mode-locked at the fundamental resonance frequency of 9.0 GHz yielding 27-ps pulses with a time-bandwidth product of 0.46. Differences in the characteristics of the pulses emitted from the two output ports indicate counter propagating pulse trains, which because of the mode-locking scheme must collide in the modulated gain section.
