“…The realisation of stable, fast and scaleable all optical memory elements would significantly increase the scope of photonic devices and has therefore attracted considerable interest in the laser community. Examples of optical memory designs include hetero-structure photonic crystal lasers [19], coupled micro-ring lasers [16] and dual mode semiconductor lasers with delayed feedback [31]. In this section, we propose a conceptually simple all optical memory element on the basis of two closely coupled single-mode lasers.…”

We theoretically investigate the dynamics of two mutually coupled identical single-mode semiconductor lasers. For small separation and large coupling between the lasers, symmetry-broken one-colour states are shown to be stable. In this case the light output of the lasers have significantly different intensities while at the same time the lasers are locked to a single common frequency. For intermediate coupling we observe stable symmetry-broken two-colour states, where both lasers lase simultaneously at two optical frequencies which are separated by up to 150 GHz. Using a five dimensional model we identify the bifurcation structure which is responsible for the appearance of symmetric and symmetry-broken one-colour and two-colour states. Several of these states give rise to multi-stabilities and therefore allow for the design of all-optical memory elements on the basis of two coupled single-mode lasers. The switching performance of selected designs of optical memory elements is studied numerically.

“…Dual-mode laser systems have attracted considerable attention because of their numerous potential applications, including terahertz frequency generation, [1][2][3][4][5] THz imaging, 6 microwave/millimeter wave generation, [7][8][9][10] optical memory, [11][12][13][14] dual-wavelength interferometry, [15][16][17] and optical switching. 18 To date, many techniques have been proposed and experimentally demonstrated to successfully produce dual-mode lasing operation, [19][20][21][22][23][24] and among these, multi-mode Fabry-Pérot laser diode (MMFP-LD) based devices are worthy of extensive investigation because of their rich variety of nonlinear phenomena, cost effectiveness, low power consumption and low threshold current.…”

In this paper, optical bistability characteristics are demonstrated experimentally based on a dual-mode laser system comprising a multi-mode Fabry-Pérot laser diode (MMFP-LD) and a built-in feedback cavity formed by a fiber facet. The results show that two lasing modes with frequency separation of ∼0.58 THz and comparable peak powers can be achieved by judicious adjustment of the bias current and the operating temperature of the laser chip, which has a peak fluctuation of less than ∼1 dBm over a measurement period of one hour. A combination of appropriate external injection power and wavelength detuning can result in remarkable optical bistability in two oscillation modes, in which the resulting contrast ratio between the unlocked and locked states can be up to 30 dB, and the corresponding hysteresis loop width can be changed by controlling the side-mode injection power and the wavelength detuning.

“…Optical bistability (OB) is a nonlinear optical phenomenon that corresponds to two states of stable output for a given input state. OB has application prospects in numerous aspects, including optical transistors, [ 288 ] all‐optical switching, [ 289 ] optical memories, [ 290 ] and limiters. [ 291 ] The current methodologies for achieving OB are mainly the Fabry–Perot cavity, [ 292 ] surface plasmon, [ 293 ] guided mode resonance, [ 294 ] and nonlinear photonic crystal.…”

In recent years, spatial self-phase modulation (SSPM) with two-dimensional (2D) materials has attracted the attention of many researchers as an emerging and ubiquitous nonlinear optical effect. In this review, the state of the art of 2D material-based SSPM is summarized. SSPM measures or tunes the nonlinearity of 2D materials, and it is also an effective approach to study the band structure of 2D materials. Several modified forms of SSPM, such as high-order, white-light-excited, vector field excited, and optically nonlinearly enhanced SSPM are also presented. Subsequently, the physical origin of the SSPM formation mechanism is compared and analyzed. Furthermore, the applications of SSPM with 2D materials, including passive photonic devices, generation of Bessel beams, and identifying the mode of the orbital angular momentum, are listed. Finally, several urgent problems of the SSPM with 2D materials, potential applications, and prospects for future development are presented.
