We use a new rate-equation model for the propagation of sub-picosecond polarized optical pulses in a semiconductor optical amplifier (SOA). This model is based on the decomposition of the polarized optical field into TE and TM components that interact via the gain saturation, and accounts for two-photon absorption, free-carrier absorption, selfand cross-phase modulation, carrier heating, and sp...

This work describes the construction of an ultra-compact narrowband fiber laser source for coherent anti-Stokes Raman scattering microscopy tags, that is, addressing resonances deuterated molecules and alkyne tags in spectral range from 2080 to 2220 cm?1. A fast electronically tunable cw seed based on a semiconductor optical amplifier (SOA) emitting around 1335 nm has been employed four-wave mi...

Coherent-Optical OFDM systems are known to be sensitive to large peak-to-average power ratio (PAPR) at the transmitter output, due to nonlinear properties of some components involved in the transmission link. In this paper, we investigate the impact of an amplification of such signals via a semiconductor optical amplifier (SOA), considering some recent experimental results. An efficient tradeof...

Wavelength conversion has been suggested as one of the key functions for wavelengthdivision-multiplexing (WDM) optical networks and photonic switch blocks. Several methods, such as a self-phase modulation (SPM), a cross-gain modulation (XGM), and crossphase modulation (XPM), can be used to realize all optical wavelength conversion (AOWC) [1-29]. However, four-wave mixing (FWM) based on nonlinea...

In this paper, we demonstrate a novel multi-section directly modulated laser transmitter for upstream operation in the application of time wavelength division multiplexing (TWDM) architecture. The photonic integrated circuit (PIC) is fabricated using regrowth-free process that favors simplified and fast manufacturing. PIC based on master-slave configuration, with an addition variable optical at...

In this paper 16 channels DWDM system at 10Gbps has been investigated with Semiconductor optical amplifier at 0.8 nm channel spacing and the performance has been calculated on the basis of bit error rate, quality factor and optical output power. It is observed that the signal can be transmitted with acceptable BER and Q-factor using Semiconductor optical amplifier at low signal input power of -...

Electronic Content Addressable Memories (CAM) implement Address Look-Up (AL) table functionalities of network routers; however, they typically operate in the MHz regime, turning AL into a critical network bottleneck. In this communication, we demonstrate the first steps towards developing optical CAM alternatives to enable a re-engineering of AL memories. Firstly, we report on the photonic inte...

We demonstrate a novel approach for generating a stable and low polarization-sensitive mode-locked fiber ring laser by using a low-cost Fabry-Perot laser diode (FPLD) as both the intracavity mode-locker and the band-pass filter. The FPLD pulses is seeded into a close-loop semiconductor optical amplifier (SOA) based fiber ring laser for harmonic and rational harmonic mode-locking operation. The ...

This paper presents our work carried out in the colorless-component technologies for high bit-rate optical access networks, which are based on WDM-PON (wavelength division multiplexed passive optical networks). The colorless concept consists in using identical and wavelength-independent components that will act as the generic transmitter in WDM-PON systems. The transmitted wavelength is imposed...

Abstract Fourier domain mode-locked (FDML) lasers are frequency-swept that operate in the near-infrared region and allow for attainment of a large sweep-bandwidth, high sweep-rate, narrow instantaneous linewidth, all which usually quite desirable characteristics laser. They used various sensing imaging applications but most commonly noted their practical use optical coherence tomography (OCT). ...
