Quasi-linear amplification device for use in optical network fields, has semiconductor optical amplifiers arranged with each other in serial manner and connected to current power supply units, and integrated device provided with substrate
NOVELTY – The device has two semiconductor optical amplifiers (3, 4) arranged with each other in a serial manner and connected to direct current power supply units (5, 6). The first semiconductor optical amplifier is used for amplifying optical signal. The second optical amplifier regenerates the optical signal. Amplitude selected among the group of optical signals. An integrated device is provided with a substrate, where wave length of the amplified signal is 600-1800 nm. The signal is received by an optical fiber line (7). Optical amplitude and phase are corrected through output (8). USE – Quasi-linear amplification device for use in optical network fields. Can also be used for electrical engineering field, physical computing filed or telecommunication field. ADVANTAGE – The two semiconductor optical amplifiers are arranged with each other in the serial manner, thus improving capacity and spectral efficiency of the device in a simple manner. DETAILED DESCRIPTION – An INDEPENDENT CLAIM is also included for a quasi-linear amplification method. DESCRIPTION OF DRAWING(S) – The drawing shows a schematic view of a quasi-linear amplification device.
