The defining feature of the design is on-chip optical path-folding to enable the needed dense packing of the Rx modules with RF input at one end and optical interrogation from the other. Chip loss is below 6 dB. The optical S/sub 11/ is low and dominated by the AR-coating of the optical facet.","PeriodicalId":354312,"journal":{"name":"International Topical Meeting on Microwave Photonics MWP 2000 (Cat.

Specifically, we present X-band examples of two types of optically controlled microwave components: those where the optical device is used as a microwave component; and those where a standard optical component is combined with standard microwave components. The former is a slot antenna controlled with a PD in the feedline; and the latter example is that of a photodiode that controls the bias to a microwave SPDT switch. This switch is integrated with a transmit/receive (T/R) active antenna, which is then used as an element of a quasi-optical T/R array.","PeriodicalId":354312,"journal":{"name":"International Topical Meeting on Microwave Photonics MWP 2000 (Cat.

For these systems to be cost effective the integration of photonics with millimeter wave components in a single module that can operate up to Q/V-band is recommended. To accomplish this high level of integration, opto-electronic monolithic integrated circuits (OEICs) must be developed and housed in low-cost packaging incorporated with antennas. Photodetectors with >50 GHz bandwidths have been developed using a new modeling software. This photodetector technology is used in an initial development of an OEIC. The demonstration of a first generation photonic module was performed using these photodetectors.","PeriodicalId":354312,"journal":{"name":"International Topical Meeting on Microwave Photonics MWP 2000 (Cat.
