In this paper, we report the use of microelectromechanical system (MEMS) switches in development of a re-configurable optical add/drop multiplexer (ROADM). The implementation of MEMS switches enables fabrication of a highly integrated 16-channel ROADM having compact size, fast re-configuration time, low driving voltage and improved reliability. The dimensions of the die for the 2x2 crossover MEMS switch are 6.5mm x 6.5mm x 1.5mm. The insertion loss of the switch is less than 1 dB. The switching time is less than 3.3ms, and the driving voltage can be as low as 10V. Over 200 million cycles of switching have been achieved. The performance of the MEMS switch and the possibility of implementing the switch in a ROADM will be discussed.
