Dynamic simulation of mode-locked quantum-dot lasers

A dynamic model of passive mode-locking in quantum-dot laser diodes is presented. It is found that in contrast with quantum-well lasers, rapid gain recovery is key for mode-locking of quantum-dot lasers. © 2008 Optical Society of America.

1.3 μm quantum-dot electro-absorption modulator

The electro-absorption properties and Stark-shift of 1.3μm InGaAs quantum dot waveguide modulators are characterized under reverse bias. 2.5Gb/s data modulation is demonstrated for the first time with clear eye diagrams and error-free back-to-back performance. © 2007 Optical Society of America.

Monolithic mode-locked quantum dot lasers

Quantum-dot active material systems are proving to be an excellent choice for mode-locked laser applications. High-power, high repetition-rate picosecond and sub-picosecond pulse generation is now readily achievable with promising results for ultra-low jitter performance. © 2006 Optical Society of America.

Single mode performance of a single mode injected locked quantum dot laser

An injection locked QD laser is demonstrated to provide single longitudinal mode operation with a 40dB SMSR and an improvement in RIN peak from 1.3-2.3GHz. Alpha factor is measured to be 0.8. © 2005 Optical Society of America.
