Frequency-dependent electric dc power consumption model including quantum-conversion efficiencies in ultrafast all-optical semiconductor gates around 160 Gb/s

Abstract

Based on nine up-to-date types of semiconductor-optical-amplifier (SOA) samples, we devised a power-consumption model of SOA-based all-optical gates as a tool to develop faster and more efficient OTDM systems for bitrates from 10 to 160 Gb/s and those over 160 Gb/s. The conventional effect of a continuous wave (cw) holding beam was included in the model. Furthermore, in this work we defined three step-wise quantum conversion efficiencies eta(1), eta(2), and eta(3) from current-injected carriers through photons. The dependence of each of the three efficiencies on the SOA-structure was studied. The total efficiency eta(T) observed for the nine SOAs ranged widely from 0.07 to 0.46. The validity of the power-consumption model was verified by systematically measuring the effective carrier recovery rate. According to our model, the power consumption of the best existing SOA-based gate for 160-Gb/s signals is 750 mW, and this increases at a rate approximately proportional to (bitrate)(2), and decreases proportionally to (1/etaT)(2).

“…Switching speed of an SOA switch reconfiguration is in nanosecond timescale. In [37], authors presented a quadratic trend of the SOA consumption as a function of the input signal power. The values of power consumption are calculated and experimentally validated in [37].…”

“…The A♯2 parameter values are reported in Table 1. • As Wavelength Converter, the Delayed Interference Signal Wavelength Converter (DISC) illustrated in Section 2.2 is used. Its power consumption has been evaluated in (Sakaguchi et al, 2007) when commercial SOA produced by some manufactures are employed. In particular we consider the B♯1 SOA characterized by a Multiple Quantum Well (MQW) type structure and produced by manufacture B.…”

“…We report in Table 2 the main parameter values for B♯1. The power consumption, measured in (Sakaguchi et al, 2007), is also reported. It equals 187mW when the WC is operating at bit-rate B=40 Gb/s.…”
