| 英文摘要 | A semiconductor light-emitting device structured similarly to an index-guided laser, but having waveguide channels that are formed at a selected small angle of inclination with respect to a direction normal to cleaved facets formed in the structure. The angle of inclination should be as least half the critical beam angle above which total internal reflection will not occur within the waveguide channels. The angled condition of the waveguide channels ensures that effective mirror losses at the facets exceed the modal gain of the device, so that lasing will not occur, even when the current and power are increased to high levels. The device produces up to 30 mW or more of output power at a large spectral bandwidth and small coherence length. |
