Abstract:
An integrated optical amplifier assembly comprising:a wavelength selective input filter (12) configured to receive an input light signal from an input optical transmission line (28), the wavelength selective input filter transmitting a selected portion of the input light signal to an amplifier stage (14), and reflecting a remaining portion of the input light signal to an express optical transmission line (30), the amplifier stage being configured to amplify the selected portion of the input light signal to form an amplified selected portion of the input light signal and optically couple to a wavelength selective output filter (18), the wavelength selective output filter being configured to transmit the amplified selected portion of the input light signal to an output optical transmission line (78) and to optically couple a common light signal from a common optical transmission line (80) to the output optical transmission line.
