Abstract

Semiconductor white sources used for illumination have attracted much attention because of the theoretical high electro-optical efficiency and potential huge application market. However the practical electro-optical efficiency for the white light-emitting diode (LED) is far from the theoretical predict. In this paper we propose a novel white light superluminescent diode (WSLD), which has two active layers, and double-wavelength reflection filter films are coated on the facets of the chip. With this design we can get superluminescent light emission at two peak-gain wavelengths, that is, blue light and green-yellow light, thus producing white light. It is shown that WSLD has much higher electro-optical efficiency and better performance than ordinary white LEDs. This novel WSLD will be a new way to realize high-flux and high-efficiency semiconductor white light source.
