The four major technologies are MEMS, LCD, piezoelectric, and SiPh waveguide, as shown in Table 3 below.<\/p>\n<ol>\n<li>MEMS OCS (Micro-Electro-Mechanical Reflector Scope), which is the most mature, has been adopted by Google TPU series, and can do 320\u00d7320 or even larger.<\/li>\n<li>LC OCS (Liquid Crystal Switching), with high reliability, is Coherent's main technology. Currently, we have shipped a variety of 64\u00d764 and 320\u00d7320 systems, with a wider range of customers than initially expected. The disadvantage is that the switching speed is a little slow (50-100ms).
