Abstract
We report a spectrum-sliced amplified spontaneous emission-injected wide-band gain laser covering a temperature range over 110/spl deg/C as well as entire 32 100-GHz-spaced channels (1533-1558 nm) in 155-Mb/s upstream transmissions over 25 km of single-mode fiber in a wavelength-division-multiplexed passive optical network. The wide-band gain laser diode employs asymmetric multiple quantum-well structure and low antireflection coating in order to widen the gain spectrum.
