Abstract
The invention relates to an optical fiber amplifier having an amplification waveguide, having a pump source and having a wavelength-selective coupler. The pump light from the pump source is coupled into the amplification waveguide via the coupler. A carrier substrate (GS) is provided, on which passive (eg. couplers, dividers) and active components (eg. amplification waveguides) of the fiber amplifier are integrated. In addition, a silicon carrier (ST1) is provided, which is fitted to one end of the carrier substrate (GS). The silicon carrier (ST1) has anisotropically etched grooves with optical components. The pump source is fixed on the silicon carrier (ST1). The optical components on silicon carrier (ST1) and carrier substrate (GS) are adjusted in relation to one another.
