Bidirectional CATV/FTTH Transport Systems Based on a RSOA

Conference on Lasers and Electro-Optics 2010, 2010
A bidirectional down-link CATV/fiber-to-the-home (FTTH) and up-link FTTH transport system is proposed. By employing −1 side-mode injection-locked and optoelectronic feedback techniques in our system, brilliant performances are experimentally observed in both downstream and upstream transmissions.

Performance Improvement of RSOA-based Coherent WDM PON Using SBS Suppression and Erasing Frequency-Dithering Tone

Opto-Electronics and Communications Conference, 2018
We experimentally demonstrate the 60-km transmission of 28-Gb/s QPSK signal in RSOA-based coherent WDM-PON system. We suppress the SBS by dithering the seed light’s frequency and erasing the dithering-tone-induced phase fluctuation for carrier phase ...

Horn-Waveguide RSOA-EAM as a Colorless Emitting Source With Reduced Crosstalk

Journal of Lightwave Technology, 2018
We proposed, designed, and fabricated a monolithically integrated horn-waveguide asymmetric reflective semiconductor optical amplifier electro-absorption modulator (RSOA-EAM) to discriminately process down- and up-stream signals for colorless optical ...

RSOA-based self-seeded transmitters: The ERMES project results and offsprings

2017 19th International Conference on Transparent Optical Networks (ICTON), 2017
The EU FP7 ERMES project focused on the development of a wavelength division multiplexed passive optical network (WDM PON) colourless self-tuning transmitter based on reflective semiconductor optical amplifiers (RSOAs) self-seeding. These transmitters represent low cost solutions to achieve self-organized wavelength access networks.

Pulse Width Modulation for Fronthaul in a Broadband-Seeded RSOA WDM PON

IEEE Photonics Technology Letters, 2016
Pulse width modulation (PWM) can support centralized radio access networks in analog optical fronthaul, avoiding the bandwidth expansion of the digital fronthaul. The PWM encodes the analog samples at the transmitter onto the duration of the on-off-keyed optical signal, splitting the sampling and quantization of the radio signal between remote radio ...

A Bidirectional WDM Transport System Based on RSOAs and Optoelectronic Feedback Technique

IEEE Communications Letters, 2010
Abstract-A bidirectional wavelength-division-multiplexing (WDM) transport system base on two reflective semiconductor optical amplifiers (RSOAs) and optoelectronic feedback technique is proposed and experimentally demonstrated. One RSOA is employed as a broadband light source and another RSOA in combination with optoelectronic feedback technique is ...
