Abstract :
Highly Er3+-doped sodium calcium silicate glass waveguide was fabricated on oxidised silicon wafers. An Er3+ absorption of 8.5 dB/cm was measured at 1.53 mu m, whereas transmission loss outside the Er3+ absorption band was estimated to be approximately 1 dB/cm. By pumping the waveguide with 120 mW of power at 975 nm the 1.53 mu m signal intensity was enhanced by 21 dB.
