Description
Summary: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-μm low-loss spectral region of optical fibers. A dual-wavelength LEDD emitting at 1.3 and 1.1 μm is demonstrated. Powers exceeding 10 μW for each wavelength at 50-mA drive current are coupled into a lensed, graded index, 62.5-μm core, 0.29-NA optical fiber.
