Good Agreement

A hybrid fiber/wireless link based on a single visible LED and free of opto-electronic intermediate conversion stages has been demonstrated for indoor communications. This paper shows the main guidelines for proper coupling in fiber/air/detector interfaces. Experimental demonstration has validated the design results with very good agreement between geometrical optics simulation and received optical power measurements. Different signal bandwidths and modulation formats, i.e., QPSK, 16-QAM, and 64-QAM, have been transmitted over 1.5 m polymer optical fiber (POF) and 1.5 m free-space optics (FSO). Throughputs up to 294 Mb/s using a 64-QAM signal have been demonstrated using a commercial LED, which paves the way for massive deployment in industrial applications.

ABSTRACTWe report the integration of single wall carbon nanotube ensembles into micro-mechanical systems to realize a new carbon nanotube micro-optomechanical system (CNT-MOMS). CNT-MOM grippers were fabricated with CMOS compatible techniques involving nanotube film formation, wafer bonding, photo-lithography, plasma etching and dry release. MOM-grippers displacement of ∼24μm was obtained from a gripper of 430μm in length under infra-red laser stimulus and continuous operation of more than 100,000 cycles was acquired. The optical power consumption of the gripper operation was estimated to be as small as ∼240μW. This study is a good example of how nano-materials could be integrated into CMOS compatible techniques for applications in high performance MEMS and nanoscale actuation technologies.
