The larger switch requires more MEMS mirrors
, which means longer connection path lengths and consequently larger collimated beams.

Other sources of commercial MEMS mirror chips are also available (8).
Figure 3 shows the MEMS mirror assembled in a custom-machined aluminum enclosure along with its external connectors.
Finally, the 1-mm dia MEMS mirror
array is constructed with a four-flexure design, with the mirror array suspended 200 [micro]m above an electrode array.
Fujitsu's development depends on MEMS mirrors to bounce light beams.
Optic power-level feedback mechanism: The tilt of the MEMS mirrors is precisely controlled thanks to a feedback loop in a built-in control function, which maintains the optical power at a fixed level.
Hence, to estimate the effectiveness of our recently developed OXC architecture, for simplicity, we just consider MEMS-based spectrum selective switches whose hardware scale mainly depends on the number of necessary elemental MEMS mirrors. Furthermore, without the loss of generality, adding/ dropping portions which can be simple 1x2 SSSs or couplers are also neglected.
Each mirror of a MEMS-based selective spectrum switch is dedicated to a spectrum slot (or spectrum band) and so, each SSS needs L MEMS mirrors. Note that all spectrum slots of a GRE are simultaneously switched by a mirror.
"An optical interferometer is used in the testing of adaptive optic systems utilizing MEMS mirrors
. Precise wideband control of the mirror drive signals and synchronization of the optical sensing system are accomplished by a selection of TEGAM instruments.
The PARC-based design uses MEMs-type mirrors that can be tilted to higher angles than traditional MEMs mirrors
, allowing the incoming and outgoing optical fiber bundles to be spaced more closely.
