采用自对准工艺制作的分段吸收式脊形波导结构发光二极管，在出光面蒸镀λ／４介质增速膜，以增大器件的自发辐射分量，增大器件耦合效率。光束发散角小。用标准单模光纤耦合后，在２５℃、１００ｍＡ下的光功率大于２０μｗ，最大可达５０μｗ。用７０支器件在５０、８０、１２０℃及１５０ｍＡＣＷ条件下进行加速老化寿命试验，在测试３５５０ｈ后，共计２４８５００器件小时，没有一支器件失效，器件性能稳定可靠。用测试结果可计算出ＲＷＧＬＥＤ的２５℃、１５０ｍＡＣＷ的平均寿命为１．２×１０６ｈ，其退化激活能Ｅα＝０．４８ｅＶ。
A self-aligning process is adopted to fabricate a segment absorption type ridge waveguide structure light-emitting diode. A λ / 4 dielectric growth film is deposited on the light-emitting surface to increase the spontaneous emission component of the device and increase the device coupling efficiency. Small beam divergence angle. After coupling with a standard single-mode fiber, the optical power at 100 ° C at 25 ° C is greater than 20μw and the maximum is 50μw. With 70 devices at 50,80,120 ℃ and 150mACW conditions for accelerated aging test, 3550h after the test, a total of 248500 devices hours, no one device failure, the device performance is stable and reliable. The test results show that RWGLED has an average lifetime of 1.2 × 106 h at 25 ℃ and an activation energy of degradation Eα = 0.48 eV.
