This manuscript tackles the issue of circuit parasitics of reflective semiconductor optical amplifiers (RSOAs), which has been often identified as the main culprit for their relatively poor modulation performance. Building upon the findings related t

We present a small-signal model of the multiple quantum well (MQW) reflective semiconductor optical amplifier (RSOA) with the accompanying parasitic circuit, followed by a numerical simulation of its modulation response. We analyze the corresponding

Reflective semiconductor optical amplifiers (RSOAs) in a fiber cavity are attractive self-seeding optical sources for wavelength division multiplexed (WDM) access networks. This paper presents an analytical model of this fiber cavity laser (FCL). The

In this paper, we present and theoretically investigate a simple and power efficient scheme for dual optical frequency comb generation residing on a single directly modulated semiconductor laser driven by two superimposed current waveforms. Our detai

In this paper we present the design and a numerical proof-of-concept of an RSOA-based colorless multilevel transmitter, suitable for use in optical network units at user premises. Simple electrical predistortion of the M-QAM modulation signal theoret

In this paper we present a wideband model of the polarization insensitive traveling-wave and reflective semiconductor optical amplifiers, with the active regions based on the bulk material and the multiple-quantum well structure. We characterize the

We present an approach for the generation of an adaptive sigmoid-like and PReLU nonlinear activation function of an all-optical perceptron, exploiting the bistability of an injection-locked Fabry–Perot semiconductor laser. The profile of the activa

Theoretical study of switching of a bistable injection-locked Fabry–Perot laser by frequency detuning variation is performed and presented. It has been found that the shortest switching time of the master laser, which allows for the slave laser to

An analytical expression for the photon lifetime in index-coupled distributed feedback laser is derived and studied at, and below, the threshold condition. It is shown that the photon lifetime considerably varies with the frequency detuning in the vi
