Abstract
We report a high speed directly modulated widely tunable dual wavelength distributed feedback (DFB) laser for THz communication application. The wavelength separation between the two modes can be thermally tuned between 96 GHz and 1510 GHz. The device can be directly modulated by high speed data at up to 25 Gb/s data rate, which facilitates high speed data modulation in a THz communication system....
