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

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.
