The time evolution of the photon density shows that the output power may be sinusoidal when<jats:italic>m<\/jats:italic>&lt;&lt;\u20091, i.e. small signal modulation, low and very high frequencies. At intermediate frequencies, in the gigahertz range, the output power is far from sinusoidal and may show the characteristic oscillations due to the large\u2010signal transients. The resonance frequency is seen to decrease as the modulation depth increases, the worst case being when the nonlinear saturation effects are not included.<\/jats:p>","DOI":"10.1108\/03321640210410805","type":"journal-article","created":{"date-parts":[[2002,7,28]],"date-time":"2002-07-28T18:57:17Z","timestamp":1027882637000},"page":"138-146","source":"Crossref","is-referenced-by-count":0,"title":["Large\u2010signal modulation of MQW long\u2010wavelength lasers"],"prefix":"10.1108","volume":"21","author":[{"given":"Jorge","family":"Manuel Torres Pereira","sequence":"first","affiliation":[]}],"member":"140","reference":[{"key":"key2022030820352278100_b1","doi-asserted-by":"crossref","unstructured":"Arakawa, Y. and Yariv, A.
