| 英文摘要 | A broadband tunable grating-coupled external cavity laser is realized by employing a self-assembled inas/gaas quantum-dot (qd) superluminescent diode (sld) as the gain device. the sld device is processed with a bent-waveguide structure and facet antireflection (ar) coating. tuning bandwidths of 106 nm and 117 nm are achieved under 3-a and 3.5-a injection currents, respectively. the large tuning range originates essentially from the broad gain spectrum of self-assembled qds. the bent waveguide structure combined with the facet ar coating plays a role in suppressing the inner-cavity lasing under a large injection current. |
