“…In such instances, Amplified Spontaneous Emission (ASE) occurs from the SOA, facing a challenge to the improvement of pulse contrast. In this study, we aimed to enhance the pulse contrast of a DC-driven SOA by injecting a Continuous Wave (CW) light as Holding Beam (HB) [1][2][3][4]. Additionally, we investigated the amplification characteristics, observing optically pumped amplification resulting from the amplified HB in the SOA.…”

The pulsed optical output of a 940-nm LD can be amplified using a current driven semiconductor optical amplifier (SOA). The pulsed light from the 940-nm LD has a pulse width of 50 ps and a repetition rate of 50 MHz, and incident on the 500-mA current driven SOA. A CW light from a 905-nm LD incident on the SOA in colinear with the pulsed light. Due to two effects of current driven amplification and optically pumped amplification, the peak power of the pulsed light was increased up to 2W and the pulse contrast was improved by a factor of 20.

The cascadability of semiconductor optical amplifier (SOA) gates by using holding light injection is numerically and experimentally investigated. Our experimental results show that the signal bit error rate after two cascaded SOA gates will be larger than 10 9 without holding light injection; however, 11 SOA gates can be cascaded with holding light injection. The results show that the number of cascaded SOA gates by using holding light injection can be strongly increased.Index Terms-Holding light injection, numerical simulation, optical network, semiconductor optical amplifiers (SOAs), wavelength division multiplexing (WDM).
