  • We analyzed photoluminescence (PL) and electroluminescence characteristics of various chirped quantum dot structures. Peaks in EL curves were contributed by excited states of quantum dots (QD), while those in PL curves by grounded states. Based on these characteristics, we suggested that superluminescent diodes with wide spectral bandwidth may be developed if chirped QD structures are designed to make a contribution by ground states to EL characteristics.

  • We have studied on the SLDs utilizing InAs chirped QD structure. The output power and spectral bandwidth are obtained as CW 40 mW at RT and about 100 nm, respectively. More high performance of SLD can be possible with optimized design for the chirped QD structures.
