Abstract
Summary from only given. This work reports the successful use of nonidentical MQWs to achieve simultaneously lasing at two wavelengths. The two wavelengths are between 1344 nm to 1514 nm, with the spectral separation tunable from a few nanometers to 170 nm. To achieve the broadband operation at two wavelengths, both the gain medium and the cavity configuration need to be engineered. For gain medium, we use nonidentical MQW structure for the broadband purpose. There are two In/sub 0.53/Ga/sub 0.47/As QWs used in our structure.
