摘要： A semiconductor light emitting device. An emitting region has an active layer which emits short wavelength light and long wavelength light caused by inducing some amount of strain. A first reflective layer reflects the short wavelength light to the emitting region, and a second reflective layer reflects the long wavelength light to the emitting region and transmits the short wavelength light. The emitting region is between the first and the second reflective layers. Thereby the short wavelength light is emitted from the second reflective layer.
