The central office includes downstream Bragg reflector lasers for generating downstream channels of different wavelengths, each channel being wavelength-locked to a corresponding incoherent light beam. The central office multiplexes the downstream channels into a downstream optical signal, demultiplexes an upstream optical signal into upstream channels of different wavelengths, and detects the upstream channels. The local office demultiplexes a downstream optical signal into downstream channels, multiplexes upstream channels of different wavelengths into an upstream optical signal, outputs it to the central office, and demultiplexes a broadband light beam into incoherent light beams of different wavelengths. Each subscriber receives the corresponding downstream channel and incoherent light beam, includes an upstream Bragg reflector laser for generating an upstream channel wavelength-locked to the received incoherent light beam, and outputs the upstream channel to the local office.

摘要： A reflective semiconductor optical amplifier includes a substrate, a waveguide with a buried heterostructure formed by sequentially laminating a lower cladding, an active layer, and an upper cladding on the substrate, the waveguide including, sequentially, respective straight line, curved and tapered waveguide regions. A current blocking layer surrounds the waveguide to prevent electric current from flowing outside the active layer. Selectively etching portions of the current blocking layer and the substrate around the waveguide forms a trench to reduce parasitic capacitance. Further features include a window region on one end of the tapered waveguide region, an anti-reflection surface on one end of the window region, and a high-reflection surface on one end of the straight line waveguide region.
