Title: Polarization-independent type semiconductor optical amplifier
Inventor: MORITO TAKESHI
IPC: H01S5/50
Filed: 2000-05-29
Abstract: PROBLEM TO BE SOLVED: To eliminate difference in gain between polarized waves for increasing the saturated light output and increasing the saturated light output when fibers are coupled with flexibility in designing the structure kept as is, by specifying the thickness and a quantity of strain of a strain bulk active layer. SOLUTION: This device includes a strain bulk active layer 3, made of bulk crystals having an expansion strain. Resonance of light due to reflection between a light incident end face 7 and a light emission end face 8 is suppressed. Signal light 9 having nearly the same wavelength as a band gap wavelength of the strain bulk active layer 3 is incident in the light incident end face 7, to inject current into the strain bulk active layer 3 and amplify the signal light 9. Amplified signal light 10 is emitted from the light emitting end face 8. This is a polarization-independent type semiconductor optical amplifier, because its single transmission gain is not dependent on the polarized state of the incident signal light 9 but is nearly constant.  By setting the thickness of the strain bulk active layer to 20-100 nm and a quantity of strain to -0.09 to -0.06%, both the increase in the saturated light output and the independence on polarized waves, which have been considered difficult to achieve, can be realized.
