We investigate wavelength conversion performance of a hydrogenated-amorphous-silicon waveguide with fast free-carrier decay time. No noticeable penalty between BER curves for 2.5-ps RZ-OOK 10-Gb/s signals of PRBS 27-1 and 231-1 was observed.
Targeting future LAN applications, we demonstrate optical time domain multiplexing operation at 172-Gb/s using integratable semiconductor devices, i.e., intersubband transition all-optical gates, very short reach modules, semiconductor optical amplifiers, and mode-locked laser diodes. Bit-error rate (<; 10-6) well below the forward error correction limit was achieved successfully.
We have developed an 8×8 hybrid optoelectronic router prototype that optimally utilizes both optical and electrical technologies, with the ability to process 10-Gbps arbitrary-length asynchronous optical packets. With it, we demonstrate error-free operation and dramatically reduced power and latency.
We report all-optical wavelength conversion of 160-Gb/s signal by intersubband transition switches with signal pulse energy as low as sub-pJ, which is enabled by newly designed InGaAs/AlGaAs/AlAsSb coupled double quantum wells exhibiting the enhanced cross-phase modulation.
We demonstrated all-optical wavelength conversion at 80 Gb/s using a cross-phase modulation of InGaAs/AlGaAs/AlAsSb coupled double quantum wells waveguide and a subsequent spectral filtering. Error free operation was demonstrated with power penalty of 1.5 dB.
In this paper, two types of dual-band receivers are proposed in order to realize the concurrent reception of two separate frequency bands for a spectrum aggregation system. The proposed receivers consist of a common intermediate frequency stage with a common oscillator and common band-pass filter. By controlling the frequency of the oscillator, the proposed receiver eliminates interference from adjacent...
