We propose a time-resolved technique based on coherent intradyne-detection to measure the short-term optical spectral line width and the long-term mode-frequency of a singlemode in a mode-locked laser. Aliasing inherent in self-delayed homodyne technique is avoided.
BOOM is a photonic integration concept that aims to develop compact, cost-effective and power efficient silicon photonic components for high capacity routing functionalities. To accomplish this, flip-chip bonding and heterogeneous wafer scale fabrication techniques are employed that enable Si manufacturing with III-IV material processing. We present in this paper the second generation of BOOM devices...
We demonstrate error-free transmission, dynamic switching and burst detection of 160Gbps packets with guardtime ~1ns through 3-nodes that include on-the-fly optical packet switching and instantaneous locking/unlocking time clock extraction subsystems.
We investigate the feasibility of an optical packet-switched ring network node operating at 160 Gb/s, by employing in-band labeling and SOA based wavelength conversion. We find error-free operation with low power penalty over the complete system.
We discuss high-speed optical signal processing for telecom applications. We focus on the optical wavelength conversion and self-clocking, respectively. In the optical wavelength conversion, we report 40 Gb/s wavelength conversion that is capable of converting the same wavelength using a single semiconductor optical amplifier. Experimental proofs are presented. In addition, we report a novel self-clocking...
We report a new family of ultra-fast all-optical wavelength converters. The device architecture employs a single SOA and filtering elements integrated in silicon-on-insulator substrates. These schemes enable high-integration density and low power consumption.
Error free low penalty 650 Gbit/s OTDM transmission is demonstrated using a polarisation independent receiver based on FWM for demultiplexing. Spectral shaping in the transmitter and filtering in the receiver are used for clock extraction.
A four input, four output multi-stage optoelectronic switching circuit is implemented on an active-passive regrown InGaAsP/InP epitaxial wafer. The circuit incorporates shallow low-loss waveguides and waveguide crossings in combination with deeply-etched low-radius (0.1 mm) waveguide bends and multimode interference couplers to enable very high density circuit design. Each stage in the circuit comprises...
We present a scalable, low latency optical packet switch for optical packets with multiple modulation formats. Results show error-free operation of 1×8 optical packet switch for 160Gb/s RZ-OOK, 320Gb/s NRZ-OOK and 100Gb/s DPSK multi-colored packets.
