چکیده

Optical quadrature amplitude modulation (QAM) is experimentally demonstrated with a low-complexity modulator based on a semiconductor optical amplifier and electroabsorption modulator. Flexible amplitude/phase format transmission is achieved. The applicability of octary QAM for coherent optical access networks with sustainable 3 Gb/s per-user bandwidth is investigated for a long reach of 100 km, and its compatibility with a potentially high split is verified.

Sampled-grating DBR laser integrated with SOA and tandem electroabsorption modulator for chirp-control - Electronics Letters

Chirp-controlled optical modulation is demonstrated using a voltage division scheme applied to a long-section phase modulator to compensate for the positive chirp of an electroabsorption modulator arranged in a tandem configuration. Both modulators are integrated with a semiconductor optical amplifier (SOA) and a sampled-grating distributed Bragg reflector (DBR) laser. The effective chirp facto...

Optical Label Encoding Using Electroabsorption Modulators and Investigation of Chirp Properties

A novel scheme of optical label encoding by wavelength conversion based on electroabsorption modulators (EAMs) is reported. Based on the experimental observations, the chirp properties of the wavelength-converted signal are discussed and a wide dynamic range of the chirp -parameter is found allowed. Compared with cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA), the EAM ha...

Colorless FSK Demodulation and Detection With Integrated Fabry–Pérot-Type SOA/REAM

A receiver for optical frequency modulated signals, based on colorless demodulation and detection, is presented. An integrated combination of semiconductor optical amplifier (SOA) and reflective electroabsorption modulator (REAM) is designed to obtain a comb-like spectral detection function, replacing the typically required costly frequency discrimination filter. The spectral properties of the ...

Analog Characterization of Low-Voltage MQW Traveling-Wave Electroabsorption Modulators

In this paper, high-speed traveling-wave electroabsorption modulators (TW-EAMs) with strain-compensated InGaAsP multiple quantum wells as the absorption region for analog optical links have been developed. A record-high slope efficiency of 4/V, which is equivalent to a Mach–Zehnder modulator with a of 0.37 V and a high extinction ratio of 30 dB/V have been measured. A detailed study of the nonl...

Sampled-Grating DBR Laser-Based Analog Optical Transmitters

Sampled-grating distributed Bragg grating (SGDBR) laser-based widely tunable optical transmitters are investigated for application in high-performance analog links. More than 45 nm tuning range, 40 dB sidemode suppression ratio, and peak relative intensity noise below 153 dB/Hz is measured. SGDBR lasers integrated with semiconductor optical amplifiers and electroabsorption modulators (EAMs) are...
