We have studied the performance characteristics of a semilinear tapered‐waveguide laser‐diode amplifier. It has been found that an improvement of over 10 dB in saturation output power can be obtained when the amplifier is properly designed. The effect of the output width of this amplifier on the saturation output power, polarization, and amplified spontaneous emission noise has been studied. © 1996 John Wiley & Sons, Inc.
