Experimental demonstration of two methods for controlling the group delay in a system with photonic-crystal resonators coupled to a waveguide
two methods controlling group delay system photonic-crystal resonators coupled waveguide
2015/8/10
We measure the group delay in an on-chip photonic-crystal device with two resonators side coupled to a waveguide.We demonstrate that such a group delay can be controlled by tuning either the propagati...

Fiber optics communications Computer holography Multiplexing
2015/5/21
Specific fibre modes are deliberately excited in a few-mode and multimode fibre using holography. The same system is also used to demonstrate holography’s ability to detect and route individual fibre ...
Improvement of Chromatic Dispersion and Differential Group Delay Tolerance of Incoherent Multilevel Signaling with Receiver-side Digital Signal Processing
Fiber optics communications Modulation
2015/6/10
Chromatic dispersion and differential group delay tolerance of 30-Gbit/s 8DPSK and 8QAM signaling is investigated experimentally, and we show 1.7 and 1.25 times enhancement of them in 8QAM signaling b...
Phase to Intensity Modulation Conversion by Third-Order Dispersion and Its Effect on Group Velocity Dispersion Measurement Using Phase-Modulated CW Light
Dispersion Phase modulation
2015/6/9
We show that phase to intensity modulation conversion induced by third-order dispersion doubles the modulation frequency, and therefore, the third-order dispersion does not affect group velocity dispe...
