Wavelength division multiplexing optical transmitter using wideband gain laser
Abstract:
A WDM optical transmitter using a wideband gain laser comprises a plurality of wideband gain lasers and a wavelength division multiplexer. Each wideband gain laser includes a gain medium with a 3 dB bandwidth of 40 nm or more at a threshold current, and it amplifies corresponding incoherent light injected into the gain medium and outputs a corresponding channel. The multiplexer multiplexes channels, outputted from the wideband gain lasers, into an optical signal in a WDM scheme and outputs the multiplexed optical signal.
