Various techniques on the growth of self-assembled compound semiconductor nano-structures (quantum dots, QDs) have been tried to enhance the controlling on size, density, emitting wavelength, uniformity in size and ordering in location of the QDs. Optimized growth conditions have been used in the application of the QD materials in opto-electronic devices. High-power, long-lifetime quantum-dot laser-diodes (QD-LDs) emitting near 1 μm, QD-LDs emitting in red-light range, 1.3 μm QD-LDs on GaAs substrate and quantum-dot super-luminescent diodes (QD-SLDs) have successfully been achieved.
Date of Conference: 20-25 Sept. 2004
