Abstract :
The planar light waveguide type optical amplifier was designed and fabricated. For the fabrication of optical amplifier, the core layer of Er-doped SiO/sub 2/ glass was deposited onto the silica cladding layer by the RF sputtering method with a deposition rate 55 /spl Aring//min. The average Er concentration of the deposited film was 0.77 wt%. Using an input signal power 20 dBm of a laser diode with 1546 nm wavelength, the gain of the optical amplifier was 5 dB with an incident pump power of 200 mW.
