The burst of the Internet bubble in 2000 has severely quenched the pace of development in the optical MEMS ﬁeld. However, it is now clear that this ﬁeld is again set to move forward as not only telecommunication but many other industries are beneﬁting from its application. We describe in this paper some of our latest achievements in the ﬁeld, showing a new type of small scale optical switch based on integrated optics, a vibration/acceleration sensor using a veryshort external cavity laser and ﬁnally, the early development result of a nano-scale tunable photonic crystal that could be used for beam steering. The diversity of the applications we demonstrate, is a clear testimony that there is indeed ‘plenty of room at the bottom’—and particularly in the natural combination of Light and MEMS!
