Abstract

A design is presented to produce analog phase shift of 0 degrees to 360 degrees in optically controlled oscillators which are subharmonically injection-locked. The proposed concept was analytically described and experimentally demonstrated by producing 360 degrees of phase shift in an 8-GHz oscillator that is indirect optically injection-locked to a 4-GHz subharmonic frequency. This design concept could eliminate the need for switched delay-line phase shifters in the T/R modules of optically controlled phased array antennas, thus making T/R modules more compact and efficient.
