Dynamic power and chirp measurements of amplified 19 ps pulses in traveling-wave and reflective semiconductor optical amplifiers using a linear pulse characterization technique
Autor: Aidan Meehan, Javier Romero-Vivas, Michael J. Connelly, Lukasz Krzczanowicz
Publikováno v: Optical and Quantum Electronics. 51
The dynamic chirp and power of amplified pulses in semiconductor optical amplifiers is of importance in the application of these devices as conventional amplifiers and in optical signal processing. Non-linear measurement techniques are appropriate fo

Dynamic power and chirp measurements of electroabsorption and Mach-Zehnder modulator pulse generators and chirp factor extraction using a linear pulse characterization technique
Autor: Aidan Meehan, Javier Romero-Vivas, Michael J. Connelly, Lukasz Krzczanowicz
Publikováno v: Optics & Laser Technology. 121:105783
Electroabsorption and Mach-Zehnder modulators are routinely used to generate optical pulses for use in optical transmission systems. Both types of modulator impose dynamic frequency chirp on the generated pulses, which can lead to significant pulse b

Modeling of Mach-Zehnder and electroabsorption modulator pulse generators and extraction of the chirp factor
Autor: Javier Romero-Vivas, Michael J. Connelly, Lukasz Krzczanowicz, Aidan Meehan
Publikováno v: 2015 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD).
The chirp factor of optical modulators is an important parameter that relates how the induced phase varies with the instantaneous power of a generated optical pulse, from which the dynamic chirp can be obtained. The two most common modulators are Lit

Enhancement of the low-frequency response of a reflective semiconductor optical amplifier slow light-based microwave phase shifter by forced coherent population oscillations
Autor: Aidan Meehan, Michael J. Connelly
Publikováno v: SPIE Proceedings.
The enhancement of the low frequency gain response of a microwave phase shifter based on slow light in a bulk reflective semiconductor optical amplifier (RSOA), by using forced coherent population oscillations (FCPO), is experimentally demonstrated.

Linear pulse characterization as a tool for all-optical signal processing
Autor: Javier Romero-Vivas, Michael J. Connelly, Aidan Meehan, Lukasz Krzczanowicz
Publikováno v: 25th IET Irish Signals & Systems Conference 2014 and 2014 China-Ireland International Conference on Information and Communities Technologies (ISSC 2014/CIICT 2014).
Semiconductor Optical Amplifiers are very promising devices for application in optical communication systems. Some of their applications include wavelength conversion, all-optical switching, optical logic, optical time division demultiplexing, etc. F

Slow light based microwave photonic phase shifter using coherent population oscillations in a bulk tensile-strained semiconductor optical amplifier
Autor: Michael J. Connelly, Aidan Meehan
Publikováno v: 25th IET Irish Signals & Systems Conference 2014 and 2014 China-Ireland International Conference on Information and Communities Technologies (ISSC 2014/CIICT 2014).
We experimentally demonstrate a microwave photonic phase shifter based on SFL in a commercially available tensile strained bulk SOA using CPO. Controllable phase shifts of up to 50 degrees are achieved through changes in both the bias current and opt
