| Abstract | A novel surface-emitting superluminescent diode (SLD) having a round active region surrounded by a circular grating is theoretically investigated. When the superluminescent light produced in the active region transmits to the passive region, it is coupled out of the device by the detuned circular grating, forming a symmetric surface-emitting beam that could not be obtained from previous devices. The calculation of the grating shows that a reflectivity below 10(-3) can be achieved and is low enough to avoid lasing. Performances of devices using single and double quantum wells in the active regions have been simulated, which confirms feasibility of the new design, but also shows that the proposed SLD is unsuitable for high-power applications because of its relatively short length of gain compared to common stripe devices. |
