Abstract

We present a theoretical model of a loss-compensated symmetric Y-junction acting as an optical beam splitter. We consider silica (SiO ₂) channel waveguides which are assumed to be highly doped with Er³⁺. The model was developed using the beam propagation method (BPM) and a fast-Fourier-transform (FFT)-based algorithm. The analysis showed that considerable gain levels, about 4.2 dB/cm at each port of the Y-junction, can be achieved for erbium concentration 2.5×10²⁰ ions/cm³, signal power 1 μW and pump power 250 mW
