| 英文摘要 | A novel microcavity semiconductor optical amplifier ( mcsoa) was proposed by incorporating top and bottom distributed bragg reflectors ( dbrs) into the waveguide structure of conventional traveling-wave semiconductor optical amplifiers(tw-soas). the incoming( outgoing) light beam incidented onto (escaped from) the waveguide structure at a oblique angle through two optical windows, where the top dbr was etched away, and anti-reflection coating was deposited. the light beams inside the optical cavity were reflected repeatedly between two dbrs and propagated along waveguide in a zigzag optical path. the performance of the mcsoa was systematically investigated by extensive numerical simulation based on a traveling-wave model by taking into account the comprehensive effects of dbrs on both the amplification of signals and the filtering of spontaneous emission( se). our results show that the mcsoa is capable of achieving a fiber-to-fiber gain as high as 40db and a low noise figure is less than 3.5db. |
