Controlling the Occurrence of Rogue Waves in an Optically Injected Semiconductor Laser via Changing The Injection Strength

The rouge waves in an optically injected semiconductor lasers are receiving a lot of interest. In this work, the generating and controlling of the rogue waves in semiconductor lasers have been investigated. For this purpose, the laser’s rate equations are solved numerically in a specified time interval, then the field amplitude and the intensity versus time are calculated and analyzed. To solve...

An optically injected mode locked laser

We study analytically and numerically a delay differential model of a passively modelocked semiconductor laser subjected to a single frequency coherent injection. The width of the locking cone is calculated asymptotically in the limit of small injection and compared to that obtained by direct numerical integration of the model equations. The dependence of the locking cone on the laser parameter...

Sudden chaotic transitions in an optically injected semiconductor laser.

We study sudden changes in the chaotic output of an optically injected semiconductor laser. For what is believed to be the first time in this system, we identify bifurcations that cause abrupt changes between different chaotic outputs, or even sudden jumps between chaotic and periodic output. These sudden chaotic transitions involve attractors that exist for large regions in parameter space.

Afrl-ry-wp-tp-2013-0022 Generation and Modulation of a Millimeter- Wave Subcarrier on an Optical Frequency Generated via Optical Injection (postprint)

A highly tunable millimeter-wave subcarrier signal is generated by optically injecting a Fabry–Perot semiconductor laser. The optically injected light, which enables microwave subcarrier frequencies well beyond the injected laser’s free-running relaxationoscillation frequency, is then on–off keyed by direct-current (dc) modulation of the injected slave laser. Adjustment of the subcarrier freque...
