摘要：

A ring-spiral coupled microcavity laser was fabricated. The ring resonator works as an oscillator and has a diameter that is slightly less than that of the spiral cavity. The spiral provides wavelength selective feedback and emits light out from the notch. As a result, the coupled cavity generates unidirectional single-frequency laser emission. Its lasing threshold is also significantly lower than a single spiral-shaped microcavity laser. (C) 2008 American Institute of Physics.
