Abstract :
A MEMS corner-cube retroreflector (CCR) is presented. It is used as a free-space optical communication transmitter in the Smart Dust project. The optical and electrical properties are greatly improved as compared to CCRs fabricated previously in the MUMPS process. Improvements include a tenfold improvement in mirror curvature, a threefold reduction of mirror misalignment, a fivefold reduction of drive voltage, a tenfold increase in resonant frequency, and an improved scalability due to the quadruplet design.
