ABSTRACT
An electro-absorption modulator (EAM) integrated widely tunable distributed Bragg reflector (DBR) laser working at 1.5â
µm is reported. By utilizing the RF resonance between the bonding wire and the EAM, a 28â
GHz modulation bandwidth is obtained. The device is modulated with up to 50 Gb/s NRZ data. At 28 Gb/s, the power penalty to obtain a 10-10 bit error rate (BER) after a 5 Km standard single mode fiber transmission is less than 0.7â
dB. Because the DBR material has a long bandgap wavelength, the wavelength tuning range of the laser is larger than 12â
nm. The DBR laser is a promising low cost tunable light source for future high capacity wavelength division multiplexing (WDM) optical communication systems.
