“…However, it was observed that a trade-off relationship existed between the jitter reduction and pulse width shortening of the gain-switched LDs. Recently, timing-jitter reduction as well as pulse width shortening, pulse amplitude enhancement, spectral linewidth narrowing, and pulse amplitude increase of gainswitched pulses from a 1.55 μm wavelength single-mode VCSEL was observed experimentally with an optimized injection laser beam wavelength [3]. Figure 1 shows the experimental setup used for timing-jitter reduction of the gain-switched VCSEL pulses with a tunable laser beam injection.…”

“…Dynamical laser output of the vertical-cavity surfaceemitting lasers (VCSELs) under injection of an external laser beam has been investigated widely for potential application to pulse timing-jitter reduction, polarization switching, alloptical flip-flop operation, and long-distance fiber transmissions [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. VCSELs are known to be low power-consuming optical signal sources compared to the existing edge-emitting laser diodes (LDs) and to be potentially useful all-optical logic gate devices in a two-dimensional array.…”

“…Beside the conventional signal source application of the stand-alone VCSELs for relatively short-distance optical communications or interconnects, the injection locking of an external optical beam to the VCSELs allows new application areas of the VCSELs possible and improves fiber transmission properties of the VCSELs' output. Weak continuous-wave (CW) laser beam injection to a gain-switched VCSEL lowered its pulse timing jitter [2,3]. Laser pulse beam injection of an orthogonal or circular polarization into a VCSEL caused a high-speed polarization switching (PS) [4][5][6][7] or spininduced polarization oscillation [8,9].…”

We review the temporal dynamics of the laser output spectrum and polarization state of 1.55 μm wavelength single-mode (SM) vertical-cavity surface-emitting lasers (VCSELs) induced by external optical beam injection. Injection of an external continuous-wave laser beam to a gain-switched SM VCSEL near the resonance wavelength corresponding to its main polarization-mode output was critical for improvement of its laser pulse generation characteristics, such as pulse timing-jitter reduction, linewidth narrowing, pulse amplitude enhancement, and pulse width shortening. Pulse injection of pulse width shorter than the cavity photon lifetime into the SM VCSEL in the orthogonal polarization direction with respect to its main polarization mode caused temporal delay of the polarization recovery after polarization switching (PS), and its delay was found to be the minimum at an optimized bias current. Polarization-mode bistability was observed even in the laser output of an SM VCSEL of a standard circularly cylindrical shape and used for all-optical flip-flop operations with set and reset injection pulses of very low pulse energy of order of the 3.5~4.5 fJ.

“…10 External optical injection into the GSL overcomes the impairments mentioned above. 11 Previous reports have shown that optical injection locking (OIL) from a spectrally pure master laser impinges its spectral characteristics (frequency and phase) onto the slave GSL. 12 This enhances several OFC spectral parameters such as optical linewidth, 13 relative intensity noise (RIN) 14 and frequency response.…”

The authors present the complete characterization of two cost-efficient photonically integrated slotted lasers that offer regrowth free manufacturing. Furthermore, the application of these devices, as multi-carrier transmitters is also investigated. In particular, the authors employ gain switching, an optical frequency comb (OFC) generation technique based on the direct modulation. The first device used is a dual section discrete mode index patterned device. It comprises two sections, implemented in a master-slave configuration to achieve optical injection locking (OIL) of the slave section. The second, a foursection device, consists of two regrowth-free Fabry-Perot lasers, also forming a master-slave configuration. The authors demonstrate that the additional sections give finer control over the OIL parameters of the device. Results show that the OIL leads to the enhancement of the modulation bandwidth, which in turn can be used to generate a broader OFC. The generated OFC is characterized to demonstrate additional improvements brought

“…However according to the analysis above, the jitters for an SLED should be less than that of a DFB or FP laser as more ASE components in the output laser for an SLED. Introducing external seeding signal has been proposed to be an effective way to reduce the jitters [156].…”
