In this paper, Europium Aluminum Benzyl Methacrylate (Eu–Al/BzMA) optical waveguide amplifier is fabricated with multiple cores of 50 μm diameters by a unique procedure known as the Mosquito method which, utilized a micro-dispenser desktop machine. The waveguides which used the optimum dispensing criteria to fabricate desired core diameter with high precision are then optically tested. The highest optical gain of 1.08 dB/cm with 0.77 dBm/cm insertion loss has been demonstrated in this device at 617 nm amplification wavelength. Suppression of concentration quenching, high compatibility with other materials, ease of fabrication, and low cost make such rare-earth-metal ion-incorporated polymer waveguide amplifiers suitable for providing gain in many integrated optical devices in the communication area.
