    • Multi-wavelength optical apparatus includes an optical emitter, and an energy transition layer positioned adjacent to the optical emitter. The energy transition layer generates multi-wavelength electromagnetic radiation when monochromatic light from the optical emitter passes therethrough. The energy transition layer includes a plurality of luminescent films, and each film is configured to luminesce at a respective different wavelength range when monochromatic light from the optical emitter passes therethrough. The plurality of luminescent films may be arranged in contacting face-to-face relationship or may be arranged in an array. The luminescent films may include rare-earth doped oxides, phosphors, metal-doped oxides, rare-earth doped nitrides, nanostructures, and/or nanostructured films, etc. The optical emitter may be a light emitting diode (LED), a laser diode (LD), an organic light-emitting diode (OLED), a resonant cavity light emitting diode (RCLED), and/or an edge-emitting diode (EELED).
    • 多波长光学装置包括光发射器和邻近光发射器定位的能量过渡层。 当来自光发射体的单色光通过其中时,能量过渡层产生多波长电磁辐射。 能量过渡层包括多个发光膜,并且每个膜配置成当来自光发射体的单色光通过其时在相应的不同波长范围发光。 多个发光膜可以以面对面的关系布置,或者可以排列成阵列。 发光膜可以包括稀土掺杂氧化物,磷光体,金属掺杂氧化物,稀土掺杂氮化物,纳米结构和/或纳米结构膜等。光发射器可以是发光二极管(LED),激光二极管 (LD),有机发光二极管(OLED),谐振腔发光二极管(RCLED)和/或边缘发光二极管(EELED)。
