Abstract
The modulation performance of c-plane blue indium gallium nitride (InGaN) based laser diode (LD) is investigated. Various design parameters, including the waveguide layer, active region, and cavity length, has been studied to reveal the carrier-photon interactions and its impact on the dynamic characteristics and high-speed performance of the laser. The results indicate that a 50 nm InGaN waveguide layer, an active region with 3 pairs of 2–3 nm quantum well/ 5–7 nm quantum barrier, and a short cavity length of 200 um, yield the best modulation performance. A low damping factor of 0.12 ns and a bandwidth exceeding 10 GHz at the optical power of 30 mW can be achieved. The results provide a practical guidance for designing high-speed blue LDs, paving the path for the realization of large bit rate visible light data links.
