Wavelength re-routing has been suggested as a viable and cost effective method to improve the blocking performance of wavelength-routed Wavelength-Division Multiplexing (WDM) networks.
We present a reconfigurable wavelength-selective switch that independently distributes 128 input WDM channels to four output ports.
In summary, MEMS-based wavelength-selective 1xK switching systems integrate channel mux/demux, switch and VOA functionality into compact, low-loss units with flattop passband characteristics.
We present a reconfigurable wavelength selective switch that independently distributes 128 input WDM channels to four output ports.
We present an experimental demonstration of a partially equipped 128 x 128 OC-192 novel wavelength selective cross connect using a broadcast-and-select architecture.
We show a N x M wavelength selective crossconnect (WSX) with flexible passbands that can route any wavelength between any input and output port without spectral gaps.
We demonstrate few-mode fiber transmission over a novel few-mode fiber based 1 x 5 wavelength-selective switch that supports fiber with 3 spatial modes.
We implement a free-space unitary transform inside a wavelength selective switch to produce rectangular shaped beams on the LCoS steering element.
Future space-division multiplexed optical networks will require wavelength routing elements that can switch spatial channels in addition to wavelength channels.
A simple wavelength control circuit is demonstrated that maintains single-longitudinal mode operation of coupled cavity semiconductor lasers over wide ranges of temperature.
