In this chapter, we will review the recent developments of Optical MEMS
for communication applications. With the rapid expansion of the field and pro-
liferation of literature, it is not possible to cover all published works. Instead, we
will focus on a selected set of applications, and discuss the design trade-offs in
MEMS devices and systems. Topics sel ected in this chapter include optical
switches, filters, dispersion compensators, spectral equalizers, spectrometers, tun-
able lasers, other dense-wavelength-division-multiplexing (DWDM) devices such
as wavelength add/drop multiplexers, wavelength-selective switches (WSS) , and
crossconnects (WXSC). ...
