Abstract
Structures and fabrication methods for achieving multiple wavelength, dual polarization laser diode arrays using single or multiple quantum well (QW) active regions that are able to support either TE-or TM-mode operation are described. Multiple wavelengths are obtained from either separate active regions, or by forcing a long-wavelength structure to oscillate at a short wavelength through bandfilling of the QW active region. By using tensile-strained QW active regions with or without separate confinement structures, multiple-wavelength dual-polarization lasers and laser arrays can be formed from a single active region.
