Injection locking in AlGaAs semiconductor laser

Theory and experiment of a single-mode diode laser subject to external light injection from several lasers

“…Very interesting cascade NDFWM effects [19] have also been identified. At stronger injection, we observe situations of undamped relaxation oscillations, similar to those observed in the classical single master-slave experiment [2]- [8], [11]. Finally, at even higher injection, chaotic behavior can be observed in some cases.…”

“…To avoid undesired optical coupling effects (passive feedback and injection locking) between the different lasers, they need to be isolated. However, it has been pointed out in many papers [2]- [11] that passive feedback and injection locking effects can rise even at very low coupling. Typically, for injection locking phenomena in one laser to occur, only some 0.001% of its own output power need to be injected into it by another laser.…”

Optical injection locking of monolithically integrated photonic source for generation of high purity signals above 100 GHz

“…The injected signal stimulates the emission inside the cavity in such a way that the SL acquires frequency and phase characteristics of the ML. This shows that OIL is an exclusively homodyne mechanism, as both SL and ML operate at exactly the same frequency [16].…”

“…To overcome this problem there are several phase-locking techniques, such as optical phase lock loop [14], optical injection locking (OIL) [15] [16], or optical injection phase lock loop [17], which could be applied. Laser phase-locking allows the frequency of the synthesised signal to be precisely set and maintained.…”

Novel photonic applications of nonlinear semiconductor laser dynamics

“…However, it was not until the early 1980s that the nonlinear laser dynamics of optically injected lasers were systematically studied (Lang and Kobayashi 1980;Kobayashi and Kimura 1981;Lang 1982). A number of research groups soon participated in the endeavor to understand these dynamics and to develop them into useful applications (Arecchi et al 1984;Tredicce et al 1985;Mogensen et al 1985;Petitbon et al 1988;Spano et al 1989;Ramos et al 1994;DeJagher et al 1996;Gavrielides et al 1997aGavrielides et al ,b, 2002van der Graaf et al 1997c;Braun et al 1997;Krauskopf et al 1998;Wieczorek et al 1999;Yabre et al 2000;Wieczorek et al 2002;Eriksson 2002;Chlouverakis and Adams 2004;Murakami and Shore 2006).…”
