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.

We have demonstrated a broadband, wavelength sensitive polarimeter suitable for multichannel polarization and PMD monitoring.

Longitudinal stress reduced the stimulated-Brillouin-scattering threshold in a highlynonlinear-silica-fiber parametric amplifier, allowing ditherless pumping.
