Small-Form-Factor All-InP Integrated Laser Vector Modulator Enables the Generation and Transmission of 256-Gb/s PDM-16QAM Modulation Format
Small-Form-Factor All-InP Integrated Laser Vector Modulator Enables the Generation Transmission of 256-Gb/s PDM-16 QAM Modulation Format
2014/11/6
We demonstrate, using a compact InP-based integrated assembly of a tunable laser and a double-nested Mach-Zehnder modulator, generation of Nyquist-prefiltered QPSK and 16-QAM signals at 32-Gbaud. We t...

Fiber design fabrication Fiber optics links subsystems
2015/5/25
A Dispersion compensating fiber working in the LP 02 mode with a figure of merit of 2200 ps/(nm·dB), an effective area of 90 μm 2 , and MPI of -37 dB is reported.
Impact of alfa-factor on SOA Dynamic Range for 20 GBd BPSK, QPSK and 16-QAM Signals
Impact of alfa-factor SOA Dynamic Range 20 GBd BPSK QPSK 16-QAM Signals
2015/5/20
Impact of SOA α-factor on dynamic range limitation decreases for higher-order modulation formats leading to undistinguishable performances of bulk and QD SOAs. Results are supported by experiments at ...
Demonstration of GMPLS lightpaths diagnosis using an all-optical sampling-based Q-factor Monitor in a network testbed
GMPLS lightpaths diagnosis all-optical sampling-based Q-factor Monitor network testbed
2015/8/6
An all-optical sampling-based Q-factor monitor applicable to multi-bitrated and formatted signals was successfully demonstrated in a network testbed. Quality of GMPLS lightpaths could be diagnosed cor...
