Abstract :
High speed transmissions up to 20Gb/s are reported using 1.55μm InP-based Quantum Dash distributed feedback lasers. Combining a directly modulated laser with an etalon filter, we demonstrate uncompensated and non-amplified SMF 10Gb/s transmissions at a constant bias current from back-to-back up to 65km with extinction ratio as large as 8dB. This result opens the way to the implementation of low cost high bit rate sources for access network applications.
