A practical dual‐wavelength light‐emitting double‐diode (LEDD) device structure is presented. This device is relatively simple to fabricate and requires a single device‐to‐fiber alignment for packaging. Additionally, the individual wavelengths can be selected within the 0.8 to 1.6‐&mgr;m low‐loss spectral region of optical fibers. A dual‐wavelength LEDD emitting at 1.3 and 1.1 &mgr;m is demonstrated. Powers exceeding 10 &mgr;W for each wavelength at 50‐mA drive current are coupled into a lensed, graded index, 62.5‐&mgr;m core, 0.29‐NA optical fiber.
