Reprogrammable Optical Phase Array (ROPA) used as a 1×6 space switch

Abstract

The design, simulation and testing of a 1x6 optical switch is presented. Switching is achieved through a voltage-controlled optical phase array. Electrode voltages are provided by a highvoltage CMOS chip. Switching angles are within 2˚.

“…Evidence of the impact of these contributions can be found in various published, accepted for publication, and submitted journal articles and conference papers, as weIl as a US provisional patent: [17][18][19][20][21][22].…”

“…In order to provide full electric control to the electro-optic switch, 64 independent voltages ranging from 0 to 300 V are required [19], which means that 64 digital-to-analog converters (DACs) are needed on chip. The larger the number of bits per DAC, the greater the control over the voltages, which maximizes the optical performance.…”
