The all-optical, electronically controlled switch ... Unit cell of the silicon photonic MEMS switch consisting of a pair of adiabatic couplers on orthogonal bus waveguides with MMI crossing ...

Optical switches may separate signals at different wavelengths and direct them to different ports. Using tiny mirrors that reflect the input signal to the output port, MEMS technology is expected ...

Other companies have designed and tried to market high-density 3D-MEMS-based all-optical switches, and they all have come up against the same technical hurdles: acceptable performance and ...

Figure 1b shows an example of an implementation of a 3-D optical MEMS switch that employs an intermediary reflective surface to fold and shorten the optical path. Actuation of the mirror is typically ...

In contrast, systems developer Draper has come up with a LiDAR-on-a-chip that uses patented, all-digital MEMS optical switches for beamsteering. Draper says its all-digital switches “provide ...
