| 摘要 |
<p>A C- and/or L-band booster optical amplifier (60) is utilized at the output (26) of a semiconductor transmitter photonic integrated circuit (TxPIC) chip (10) or the optical combined outputs (26) of multiple semiconductor transmitter photonic integrated circuit (TxPIC) chips (10) employed in an optical communication module, the deployment of integrated semiconductor optical amplifiers (SOAs) on the TxPIC chips can be eliminated. This would reduce both the complexity in designing and fabricating these chips as well as reducing the power consumption of the TxPIC chips. The deployment of such a Tx booster optical amplifier (60) would also take into consideration the nonlinear effects of difficult high loss single mode fiber (SMF) or other fiber type links by allowing a higher power per channel to be achieved compared to the case where channel amplification is attempted solely on the TxPIC chip.</p> |
