Abstract :
Surface micromachined corner cube reflectors made of 250 μm square hinged polysilicon plates have been demonstrated to transmit digital signals over a range of 2 meters by reflecting an interrogating 5 mW laser. Measured reflectance ranges from 34% to 77% for different mirror designs. Divergence of light reflected by CCR ranges from 15-35 mrad. The CCRs are electrostatically actuated with 10 to 20 V. The highest data rate transmitted with a CCR is 1 Kbps
