Publication number: 20210194216Abstract: Stacked edge-emitting lasers having multiple active regions coupled together using tunnel junctions. The composition of each of the active regions (quantum wells and/or barriers) differs to provide a controlled different emission wavelength for each junction, when each junction is individually operated at the same fixed temperature. When the device is under operation, a thermal gradient exists across the junctions, and the emission wavelengths of each junction coincide as the different temperature for each junction causes relative wavelength shifts. Thus, the effect of temperature on the emission wavelength of the device is compensated for, producing a narrower linewidth emission.Type: ApplicationFiled: December 22, 2020Publication date: June 24, 2021Inventors: Aymeric MAROS, Bed PANTHA, Radek ROUCKA, Sabeur SIALA
