| Abstract: | A superluminescent diode (SLD) using J-shaped ridge waveguide and chirped multiple InAs quantum dots (QDs) with three different energy bandgap wavelengths, which are controlled by QD size, is demonstrated. The fabricated QD SLDs exhibit high continuous wave output power of 32 mW and wide spectral bandwidth up to 98 nm, covering the range 1084-1182 nm. |
