The suppression ratio for neighboring channels was estimated to be more than 15 dB. Since the polarization state of the incoming signal is not always constant, the polarization insensitivity is an essential requirement for stable operation of an optical demultiplexer. 5 dB by applying tensile strain to an InGaAsP-based MQW electroabsorption layer, so that polarization-insensitive demultiplexing is secured.
34 Output power variation of 80-Gb/s OUT 2 as a function of the operation temperatures of EAM 2 and EAM 4 . 35 CW output power variation at 160-Gb/s ports as a function of the offset temperature . 36 shows the block diagram of a 160-Gb/s OTDM transmitter, consisting of an optical pulse source and an optical multiplexer. The optical pulse source generates a 40-GHz pulse train, and is launched to the 160-Gb/s optical multiplexer. At the multiplexer, the pulse stream is converted into four 40-Gb/s data streams and then bit-interleaved to a 160-Gb/s signal.
Triangles and circles correspond to the output pulse width measured at the ﬁrst EAM and the second EAM, respectively. 7 nm. 28 Modulation E/O response and return loss characteristics of an SPM-EA modulator . 29 Optical pulse source with two-stage EA modulators . (Reproduced by permission of ©2005 IEICE) the applied bias was kept the same for each EAM. The average light power launched to both EAMs was set at 10 dBm. 2 ps was obtained below the bias of −3 V. 11). Another important advantage of cascaded EAM structure is in enhancing the pulse extinction ratio.
