We propose a scalable GE-PON over OCDMA system without sacrificing upstream bandwidth and experimentally demonstrate burst-data transmission of 2xGE-PON systems over 2timescodes using 10 Gbit/s capable 63-chip, 640 Gchip/s SSFBG en/decoder.
We present a hybrid burst-mode CDR employing high-speed samplers and a Gated VCO for 10 Gbps PON. With a G-VCO supported half-rate sampling technique, a large tolerance to the pulse distortion over 0.64 UI was successfully shown.
The two-photon absorption (TPA), the free-carrier absorption (FCA), and the carrier plasma effect play important roles in Si-based photonic devices. These effects have been incorporated directly into a finite-difference time-domain (FDTD) simulator for the first time. To check the validity of the FDTD simulator, it has been applied to the simulation of nonlinear transmission of an ultrashort optical...
We demonstrate fabrication of the first AlN-waveguide-based intersubband transition device. The device can operate at 1.3 mum, confirmed with the new waveguide-coupling measurement method. The intersubband absorption saturation in the device is also successfully demonstrated.
