| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We demonstrate that the apparent emission colors of InGaN-based LEDs using micro-structured multifacet quantum wells as active layers can externally be controlled over a wide spectral range that encompasses green to blue or white at a color temperature of 4000 K to blue along the Planckian locus. The controllability relies on facet-dependent polychromatic emissions. The pulsed current operation with the appropriate duties varied their relative intensities and the consequent apparent colors without seriously affecting the total number of emitted photons, particularly for the blue to green variation. The proposed LEDs can be fabricated through a simple process and, therefore, may be a key device for advanced SSL. | |
