We evaluate the system performance degraded by first-order polarization-mode dispersion (PMD) for non-return-to-zero (NRZ) or return-to-zero (RZ) differential phase-shift keying (DPSK) signals.

A polarisation-insensitive optical heterodyne receiver, in which two signals with orthogonal polarisations are independently detected and demodulated, and subsequently combined, has been demonstrat

A polarisation-independent wavelength converter using cascaded nonlinearities in periodically-poled LiNbO3 waveguides has been developed.

Well-organised harmonic madelocking with up to 12 pulses in a 1.5 mum polarisation-maintaining erbium soliton fibre laser is achieved.

Polarisation-mode dispersion (PMD) induced system outages in dispersion-managed (DM) soliton systems are investigated.

The effect of a classical electron gas on the cavity polariton linewidths is studied experimentally at T = 80 K in a GaAs/AlAs microcavity with an embedded quantum well.

We discuss polariton formation in high-quality stress compensated crack-free A10.13Ga0.87N/A10.56Ga0.44 N microcavities grown by molecular beam epitaxy on thick GaN templates.

We review the spectroscopic and dynamic properties of cavity polaritons in a X-wide GaAs/GaAlAs microcavity (MC) structure having a single GaAs/AlAs quantum well in which a variable density two-dim

All-optical wavelength conversion is demonstrated at 40 Gbit/s, using a single SOA and a bandpass filter.

The threshold behavior of an index-guided distributed feedback semiconductor laser is analyzed theoretically with particular attention paid to the effect of internal stress on the polarization of t
