Abstract
We present a distributed Bragg reflector (DBR) laser/modulator photonic integrated circuit capable of transmission over 674 km of conventional fiber at 2.5 Gb/s. Transmission was performed at four wavelengths over a range of >4 nm. The bit error rate (BER) sensitivity achieved at each wavelength varied by less than 1.1 dB. These results produce a record bit rate-distance product at each wavelength of 1.7 Tb.km/s for monolithic transmitters through nondispersion shifted fiber. Such devices are ideal sources for multichannel wavelength-division-multiplexed (WDM) transmission systems.Keywords
