— The first fully integrated array of High Voltage (HV) Digital-to-Analog Converters (DACs) was designed in DALSA Semiconductor's 0.8um CMOS/DMOS HV process technology. The 6-bit 300V DACs are based on a current-steering, thermometer coded architecture and show a DNL of 0.16 LSB and an INL of 0.18 LSB. The current-to-high-voltage conversion is done using a… (More)
The design and simulation of a 1×N optical switch is presented. Sub-¿s switching is achieved through a voltage-controlled optical phase array. Electrode voltages are provided by a high-voltage CMOS chip. Switching angles are within 2°.
We propose two novel electro-optic (EO) deflectors based on two new nonrectangular geometries: the parabolic and the half-horn configurations. These devices not only provide excellent deflection angles, but also have the potential to build nonblocking 2 x 2 optical switches. A deflector figure of merit is defined, and comparisons with existing EO deflectors… (More)
A novel reprogrammable optical phase array (ROPA) device is presented as a reconfigurable electro-optic element. One specific application of the ROPA, a 1 x 6 electro-optic space switch, is fully described. Switching angles are within 2 degrees , and switching is achieved through a complementary metal-oxide semiconductor (CMOS) controlled, diffraction… (More)
