Monolithic, multiple wavelength, dual polarization laser diode arrays

摘要

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.
