High Efficiency Optical Switches with Heater-on-Slab (HoS) Structures
Couplers Switches Multiplexers Waveguides Slab
2011/5/21
We propose optical switches in which the heater is fabricated directly on the slab region of the rib waveguide. Two types of Heater-on-Slab (HoS) switches were investigated. In the first type, the sil...
100Gb/s dual-carrier DP-QPSK performance after WDM transmission including 50GHz Wavelength Selective Switches
100Gb/s dual-carrier DP-QPSK performance WDM transmission Wavelength Selective Switches
2011/5/18
Using a real-time intradyne receiver, we characterize the tolerance of a 100Gb/s dual-carrier dual-polarization-QPSK signal to carrier frequency separation and frequency offset after WDM transmission ...
Scalability of Optical Intermodule Interconnects for Switches and Routers Comprising 100 Gb/s Line Cards
Optical interconnects Fiber optics optical communications
2010/6/4
We analyzed scalability limitations of various optical interconnection solutions for rack-to-rack applications with respect to required number of interconnecting fibres and power consumption.
All-Optical Wavelength Conversion at 160Gb/s by Intersubband Transition Switches Utilizing Efficient XPM in InGaAs/AlAsSb Coupled Double Quantum Well
Wavelength Conversion Coupled Double Quantum Well
2009/7/14
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 co...
Wavelength Selective Switches time requirements for shared path protection in ASON/GMPLS rings
Wavelength Switches time shared path protection ASON/GMPLS rings
2008/8/6
We analyze the protection time provided by the shared path protection scheme in GMPLS-based optical rings, as a function of the switching time of the Wavelength Selective Switches (WSS).
Ultra-Compact Photonic-Crystal-Based Tuneable Mach-Zehnder Interferometer for Low-Power Integrated Optical Switches
Photonic-Crystal Tuneable Mach-Zehnder Interferometer Low-Power Integrated Optical Switches
2008/8/4
The “slow light” property and wide-band 90°-bends of pillar-photonic-crystal waveguides enables entire-C-band ultra-compact optical devices. We demonstrate tuneable Mach-Zehnder interferometers with a...
