Description
Summary:This paper demonstrates a four-element integrated photonic radio-frequency (RF) phase shifter array in a single chip with an advanced configuration. These devices are integrated using electrooptic polymer materials and involve several novel technologies. Measurements of this configuration showed that our four outputs were independent and had highly linear RF phases over 360/spl deg/ with negligible RF power fluctuation at the modulation frequency of 20 GHz. This significant improvement is capable of removing one of the major problems in using this type of phase shifter architecture.
