摘要： A semiconductor optical amplifier comprising an active gain region of the (In,Ga)(As,N) system is proposed, together with the use of (Ga,In)(As,N) as the base material for the fabrication of an SOA, and a semiconductor optical amplifier comprising (Ga,In)(As,N) as the base material. The N content of the (In,Ga)(As,N) can be varied along a dimension of the active region in the direction of propagation of light signals therein, to create a varying bandgap such as for mode expanders. The active region can be supplied by a source of electrical bias which is applied in segments along the dimension of the active region, the segments being capable of independent variation. This should allow channel equalisation of WDM signals to be performed dynamically. This scheme could also be used to equalise device parameters such as differential gain, saturation output power and linewidth enhancement factor across the amplification bandwidth.

摘要： A surface-emitting optical amplifier (10) having a generally circular waveguide (30) and active region (20). The waveguide (30) and active region (20) match the shape of an optical fiber or other device for generating, transmitting, guiding, propagating, etc., an optical signal. For example, the shape of the waveguide (30) and active region (20) may be circular, elliptical, square, rectangular, or virtually any other required shape. By matching the shape of the waveguide (30) and active region (20) to the shape of the device to which the waveguide connects, coupling loss is reduced and polarization dependent loss is eliminated due to the symmetry of the active region. The reduction of the coupling loss also leads to an increase of the signal to noise ratio since the signal loss from the input coupling is directly reduced.

摘要： An optical signal amplifier includes a Raman fiber amplifier and a semiconductor optical amplifier. The Raman fiber amplifier utilizes a portion of the pump radiation to amplify the optical signal resulting in an amplified optical signal and a residual pump radiation. The semiconductor optical amplifier receives the amplified signal and the residual pump radiation and utilizes the residual pump radiation to increase a saturation output power of the semiconductor optical amplifier while amplifying the amplified signal resulting in a twice amplified signal.
