Title

Interferometric Measurement Of The Linewidth Enhancement Factor Of A 1.55 µm Strained Multiquantum-Well Ingaas/Ingaasp Amplifier

Abstract

The linewidth enhancement factor of an InGaAs /InGaAsP strained multiquantum well optical amplifier was measured interferometrically. It varied from 3 to 18 over the wavelength range from 1500 to 1600 nm with injection currents varying from one to four times the lasing threshold of the uncoated device. A rate equation model gave differential gain and refractive index change per carrier, respectively, in the range 0.3 to 2.5 × 10 cm2 and -5 to -8 ×20 cm3. © 1992 IEEE
