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 ...

BCO produces a siliconsubstrate for optical MEMS switches and other silicon-on-insulator(SOI) products. Cypress Semiconductor acquired Silicon LightMachines in July, 2000. SLM and Cypress have ...

Lucent was among the first to announce a MEMS-based optical-switching technology, and others quickly followed. The 256 x 256 array seems to be the size preferred by switch makers, with 1,000 x 1,000 ...

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 ...

In contrast, Draper has developed, and recently advanced, a LiDAR-on-a-Chip that uses patented, all-digital MEMS optical switches for beamsteering. Draper's all-digital switches provide robustness ...
