Pure Q-switching (self-pulsating) behaviour is shown for the first time in an optically injected two-section quantum-dot laser. Upon CW optical injection, it was possible to switch the operation regime from free-running mode-locking to locked Q-switc

We present a model for the description of the dynamical behavior of Quantum Dot (QD) based Semiconductor Optical Amplifiers (SOAs) under injection of optical pulses. The model uses a Time Domain Traveling Wave (TDTW) approach to describe the optical

We introduce a rate equation based numerical model suitable for the description of the wide spectral asymmetry experimentally observed at the two facets of multi-electrode tapered superluminescent diode based on Quantum Dot material. Numerical simula

A wide spectral asymmetry between the wide and narrow facets of a two-section tapered quantum dot (QD) superluminescent diode (SLD) emitting around 1240 nm was observed and investigated. This asymmetry, as characterized by the mismatch in the center

Double-pass amplification using tapered semiconductor optical amplifiers (SOA) enables a potential improvement in gain and output power compared to standard single-pass configurations, particularly at low input optical power. The potential of double-

Combining the output of two or more separate, distinct superluminescent diodes (SLDs) via spectral multiplexing has the potential to produce very wide optical spectra which could prove beneficial in imaging applications1. Likewise, the implementation

Superluminescent diodes (SLDs) with high power spectral density present an appealing low cost, small footprint and relatively simple alternative to supercontinuum sources for spectroscopy applications that do not require extremely broad optical spect

A high-power quantum-dot superluminescent diode is demonstrated under continuous-wave operation, with an output power of 137.5 mW and a corresponding spectral bandwidth of 21 nm. This represents not only the highest output power, but also a record-hi

A wide spectral asymmetry between the front and rear facets of a tapered chirped quantum dot multi-section superluminescent diode is reported. The spectral asymmetry between the two facet outputs was found to be tunable and highly dependent on the bi
