“…The experimental result demonstrates the dualbeam optically injected semiconductor laser has the ability to generate a stable microwave signal with wide frequency tunability. Note that there are few reports on all-optical microwave signal generators implemented by a dual-beam optically injected semiconductor laser [15]- [17]. Among them, only [17] provides investigation results on the frequency stability of the generated microwave signal.…”

“…Several dual-beam optically injected semiconductor laser based microwave photonic signal processors, e.g. microwave signal generators [15]- [17], a dual-chirp microwave waveform generator [18] and a dual-passband microwave photonic filter [19], have been developed. Many previous investigations on dual-beam optical injection were conducted when the two injection beams from the master laser (ML) have a small frequency separation and their frequencies are less than or around 20 GHz away from the SL free running frequency.…”

This paper presents a detailed experimental investigation of the nonlinear dynamics of a dualbeam optically injected semiconductor laser. Unlike previous works, we focus on the situation where the power and the frequency of the injection light wave are fixed and the free running frequency of the laser subject to optical injection is in between the two injection beams that have a large frequency separation. The nonlinear dynamics of the slave laser (SL), i.e., the laser subject to optical injection, for different SL forward bias currents are examined. Results show, in addition to the regenerated injection light wave, a fundamental oscillation together with its harmonics are generated when the SL is interacted with its nearby injection beam. The SL output frequency components are stabilised when one of the harmonics of the fundamental oscillation is located at the injection beam that is far away from the free running SL. More than six-fold improvement in the frequency stability of the resultant output microwave signal, compared to that generated by optical mixing, is obtained. Experimental results also show the SL nonlinear dynamics have different behaviours when the two injection beams have different frequency separations.

“…In this case, various nanostructures viz. quantum well [13], quantum dash [14]- [16], and quantum dot [17], [18] based lasers have been engaged. Hence, a compact coherent multiple wavelength visible laser diode with narrow and uniform wavelength spacing is of paramount importance to facilitate high capacity wavelength division multiplexed visible light communication (WDM-VLC) system, which is considered as a viable last mile-access network infrastructure.…”

Single and multiple wavelength laser systems are presented that employ self-injection locked InGaN/GaN green laser diode in an external cavity configuration with a partially reflective mirror. A stable and simultaneous locking of up to 4 longitudinal Fabry-Perot modes of the system cavity is demonstrated with appreciable signal-to-noise-ratio (SNR) of ~13 dB and average mode linewidth of ~150 pm. The multiwavelength spectrum exhibited a flat-top emission with nearly equal power distribution among the modes and an analogous mode spacing of ~0.5 nm. This first demonstration of multiwavelength generation source is highly attractive in a multitude of cross-disciplinary field applications besides asserting the prospects of narrow wavelength spaced multiplexed visible light communication. Moreover, an extended two-stage self-injection locked near single wavelength visible laser system is also presented. An ultra-narrow linewidth of ~34 pm is realized at 525.05 nm locked wavelength from this innovative system, with ~20 dB side-mode-suppression-ratio (SMSR); thus signifying a paradigm shift towards semiconductor lasers for near single lasing wavelength generation, which is presently dominated by other kinds of laser technologies.

“…The discrete energy states of QDs result in many unique features such as sharp optical transitions, high differential gain, low temperature sensitivity, and enhanced optical nonlinearities. QD-SOAs have also displayed enhanced ultrafast nonlinear optical response on very short time scales [10][11][12]. The enhanced nonlinear response can be utilized to realize efficient microwave and millimeter-wave signal generation, all-optical signal processing, all-optical wavelength conversion, and add-drop functionalities.…”

A novel type of multichannel and multistate all-optical switch using a single sample-grating quantum-dot-distributed feedback semiconductor optical amplifier has been proposed and theoretically demonstrated. The multichannel device, which operates below threshold, utilizes cross-gain modulation and the sample-grating technique. The multichannel outputs are strongly coupled and are utilized to get multistability at several wavelength channels. Three logic states can be obtained when the inputs are properly detuned to the sample-grating comb modes. The three logic states, which exhibit reasonable gain, are separated by wide hysteresis width and can be tuned to a different wavelength channels. The device characteristics are very useful for building all-optical logic gates, flip-flops, and decision circuits.
