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.

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.
