| 摘要 |
The present invention relates to a laser structure (100) on a semiconductor substrate which comprises a first resonator (110), a second resonator (120) and a third resonator (130). The second resonator (120) and the third resonator (130) are designed as ring resonators and are arranged in at least one common section next to the first resonator (110) or next to the second resonator (120), respectively, substantially at a constant spacing from the first resonator (110) or from the second resonator (120), respectively. As a result, the second resonator (120) is optically coupled to the first resonator (110), and the third resonator (130) is optically coupled to the first resonator (110) via the second resonator (120) or directly, respectively, in such a way that a standing wave with a defined wavelength can form in the first resonator (110).
