Graded-bandgap quantum-dot lasers and arrays

Novel bandgap-engineered quantum-dot devices are reported: a dual-wavelength laser, a gain-broadened laser/amplifier employing a bandgap-graded cavity, and a multi-wavelength laser array with a 20 nm tuning range at 1280 nm. The devices are realized using a multi-bandgap post-growth intermixing tech...

Description
Summary:Novel bandgap-engineered quantum-dot devices are reported: a dual-wavelength laser, a gain-broadened laser/amplifier employing a bandgap-graded cavity, and a multi-wavelength laser array with a 20 nm tuning range at 1280 nm. The devices are realized using a multi-bandgap post-growth intermixing technique.
