As a fundamental optical approach to interferometry, Sagnac interference has been widely
used for reflection manipulation, precision measurements, and spectral engineering in …

Nowadays, optical devices and circuits are becoming fundamental components in several
application fields such as medicine, biotechnology, automotive, aerospace, food quality …

Low-cost chip-scale optoelectronic gyroscopes having a resolution≤ 10°/h and a good
reliability also in harsh environments could have a strong impact on the medium/high …

Synchronisation of two unidirectionally coupled semiconductor ring lasers working in a
chaotic regime (transmitter and receiver) is studied numerically. Two different configurations …

We study semiconductor ring lasers subject to delayed optical feedback from one or two
short external cavities. In case of two cavities we consider the feedback strengths and …

We report transmission spectra and mode-field distributions of a waveguide-coupled spiral-
shaped microdisk resonator on a silicon nitride-on-silica substrate. Our measured and …

Integrated ring laser gyroscopes are perfect candidates for small-sized and high-
performance gyroscopes. However, the performance of the ring laser gyroscope (RLG) near …

The insensitivity to optical feedback is experimentally measured for a semiconductor ring
laser (SRL) and compared to that of a Fabry–Perot laser (FPL) fabricated with the same …

We report fabrication and characterization of semiconductor ring lasers with quantum-dot
active region. The In As∕ In Ga As∕ Ga As “dots-in-a-well” ridge-waveguide ring lasers are …

We propose and demonstrate a selection scheme of lasing direction by imposing a loss
imbalance structure into the single mode square ring cavity. The control of the traveling …
