Silica/Electro-optic Polymer Optical Modulator for MMW Receiving (Preprint)

Abstract

A silica/electro-optic (EO) polymer phase modulator is proposed for millimeter-wave (MMW) radiation receiver with the use of a bowtie antenna. Waveguide design optimization is presented for a waveguide with an EO polymer core and silica/solgel cladding. Electrode effects on the insertion loss and poling efficiency are also analyzed and conditions for low-loss and high poling efficiency established. The bowtie antenna is simulated and shows a broadband response with a maximum at 5GHz and a 3dB-bandwidth of approximately 12GHz. A fiber splicing technique is presented that reduces coupling loss between SMF-28 and the waveguide. Experimental results for a fabricated device with MMW-response between 10-14GHz are shown with carrier to first sideband intensity difference of up to -36dB.
