Period-doubling route to chaos in a semiconductor laser with weak optical feedback

Dynamic behaviors of a broad-area diode laser with lateral-mode-selected external feedback

“…In Ref. 8, a period-doubling bifurcation is responsible for the observation of peaks with spacing of c/4L. The similar bifurcation behaviors were also observed in other nonlinear feedback system 23 .…”

“…For curve e), we believe the external cavity is also established between the feedback mirror and the BAL, but it seems only one external-cavity mode is excited, thus no peaks are observed in the noise spectrum. The peak spacing of double roundtrip external-cavity mode in noise spectrum has been observed in both narrow-stripe diode laser with ordinary feedback 8 and phase-conjugate feedback 22 , and BAL with tilted feedback 12 . In Ref.…”

“…The complex dynamic behaviors have been studied intensively for both narrow-stripe diode lasers [8][9][10][11] and BALs [12][13][14][15][16][17][18][19] with either a conventional mirror or a phase conjugator external feedback. The dynamic behaviors of BALs have been studied with short-cavity feedback 15,16,19 , long-cavity feedback 14,17 , and tilt mirror feedback 12,18 .…”

Complex photonics: Dynamics and applications of delay-coupled semiconductors lasers

“…3, determines the excentricity of the ellipse. In a similar regime of weak feedback, a route to deterministic chaos via perioddoubling bifurcations has also been identified (Ye, Li, and McInerney, 1993). A detailed experimental and numerical study by Hohl and Gavrielides (1999) provided further insight into the sequence of routes to chaos, when the feedback is increased in small steps.…”

Frequency dynamics of gain-switched injection-locked semiconductor lasers

“…Instabilities can occur even when the master and slave frequencies are perfectly matched, due to the depressed carrier number induced by optical injection. The dc biased slave laser exhibits several behaviors depending on the injection level and the frequency mismatch between the two lasers, including steady states [16], periodic self-oscillations [17], chaotic output [18]- [20], low-frequency fluctuations [21], four-wave mixing, and frequency conversion [22], among others. The steady state, in which the slave laser is frequency-locked to the master laser, has received particular attention [16], [23], [24].…”
