“…In addition, we showed that Eqs. ( 1) and (2) were unresolved after 1250 mA in previous studies [25]. In this case, the 1st and 2nd regions are appropriate for practical applications of the laser diode.…”

“…The state of the optical output power is specifically important due to the effects of intermodulation distortion on applications and subcarrier systems. One especially important feature is the effect and fluctuation of optical power, which is more evident and greater when a low DC supply current (I o ) is applied [24][25][26][27][28][29][30][31]. As the amount of power increases to a certain level, the power fluctuation may be reduced significantly.…”

Abstract:In this study, the rate equation analysis of a BH-laser diode was performed for output carrier density ( No) using the zero-degree solution of the Volterra series. The carrier rate equation of the laser diode was analyzed in terms of input carrier density ( Ni) and output carrier density modeling ( Ni − No) , with respect to the DC current ( Io) .The polynomial root, which is obtained from the zero-degree solution ( No) and limit values of Io , was found. For the linear operation of the laser diode, the range of Io current was also determined using a linearization approach and the maximum value of No .

“…This limits the application of OIL lasers in practical applications. A high damping ratio and low settling time must be required for high-speed digital modulation [30]. To meet the requirements, we propose the preprocessing of a direct modulation signal for the OIL laser.…”

Modulation Performance Enhancement of Directly Modulated Injection-Locked Semiconductor Lasers Using an Equivalent Electrical Circuit

We propose an equivalent electrical circuit model to evaluate the direct modulation performance of optically injection-locked (OIL) semiconductor lasers. We modeled the equivalent circuit of the OIL laser based on alternating complex envelope representations, simulated it using the Simulation Program with Integrated Circuit Emphasis (SPICE), and analyzed the frequency response of the OIL laser. Although the frequency response of the OIL laser is better than that of a free-running laser, its 3-dB modulation performance is degraded by the relaxation oscillation that occurs during direct modulation of the semiconductor laser. To overcome this limitation and maintain the maximum modulation performance within the entire locking range, we also designed an electrical filter to preprocess the electrical modulation signal and compensate for the non-flat modulation output of the OIL laser. The damping ratio of the directly modulated OIL laser increased by 0.101 (280%) and its settling time decreased by >0.037 (44%) when the electrical compensation circuit was added, exhibiting a flat 3-dB modulation bandwidth of 28.79 GHz.

Four-tone small signal analysis was performed for a nonlinear optoelectronic feedback laser diode system. In the analysis, Volterra power series up to second-order opening, the second kernel for the output intermodulation distortion (IMD) analysis was performed. The components of the alternative IMD frequency were selected for analysis. These are the four IMD frequency components. The variation of IMD frequency component amplitudes was investigated under various values of delay-time (t0) and the feedback gain constant (K). The feedback values and the critical frequencies, at which the coherence collapse or chaos occur, were also determined.
